‘Breeze Easily’ – December 2020 edition.

Note: This field is developing rapidly,  so I continually update this article. If you aren’t here already, always click on http://www.sheffieldcycleroutes.org/e-bikes/  for the most up to date version before you read on.

This article gives a general explanation and overview of e-bikes and their usage. It describes a wide range of e-bikes available for different purposes.

It is aimed both at people who are new to the idea and contemplating the purchase of an e-bike, and those who already have one and want to know more about its use and care.

Over the several years since our initial dip into electrically assisted cycling the author and his partner have come to find themselves using e-bikes as default everyday transport, valuing their convenience and fun factor.

We have found that in Sheffield, like the trams, a more powerful than average motor system will serve you best, and the occasional bias here towards higher quality, more powerful e-bikes reflects that.

The article also covers cycling resources generally in the hilly Sheffield area and beyond.

The Short version: After 7 yrs of everyday ‘Utility’ transportation on a few different e-bikes in Sheffield (as opposed to mainly leisure or fitness oriented use) my partner and I conclude that:

For comfortable, reliable and breezy day to day e-bike usage around Sheffield, choose a locally sourced upright-ish seating position ‘Hybrid’ style model with a Mid mounted motor (rather than one with the motor in one of the wheels). It should have at least 50Nm of motor power, at least 8 gears, and be fully kitted out with mudguards, lights and a pannier rack. Secure it with a properly serious lock or two at all times, including at home. Top up the battery little and often, and keep it well serviced.

You will find yourself using such a model to do many of the journeys you are currently spending a lot of money on in terms of fuel and running costs, parking charges, or bus, tram and train fares etc, and, like us, you may find yourself unexpectedly selling your 2nd vehicle, or even your first!

1. So what exactly is an ‘e-bike’?  

E-bikes – ‘EAPC’s (Electrically  Assisted Pedal Cycles) or ‘Pedelecs’ come in as many variations as ordinary bikes, and you will find different types described as you read. The type we use for utility and leisure duties around town are essentially just sturdy everyday upright sitting position bicycles built around an electric motor, a battery and a controller.

You still need to pedal before the power cuts in, so it feels just like a ‘normal’ bike. On an e-bike inbuilt sensors detect when and how much you push on the pedal, and then the level of electrical motor power you have pre-selected is automatically added to your efforts.

Note: You have full control over the amount of assistance you want as you pedal. You can choose from low, if you want a good workout, through various levels right up to the top level, which will provide a very welcome ‘ just get me home it’s been a long day’ setting!

Most systems give you 3 or 4 levels of assistance to choose from, or indeed no assistance at all if you prefer, eg if you are running low on battery, or just want a good workout on the pedals.

Under UK law that assistance has to electronically cut out above 15.5mph, but you can then pedal faster than that under your own power, just as on a normal unassisted bike.

On Utility focussed bikes the 30% or so extra weight of the motor, battery, accessories etc,  means you mostly find yourself happily bowling along at a nicely assisted 10-15mph, making e-bikes ideal for local/urban transport and commuting.

Note: As we exit the EU we will have the opportunity to consider increased max assisted speed limits on e-bikes.

Instead of the current EU 15.5mph cut off limit for assistance, we could for example align ourselves with the US, where e-bikes are typically allowed 750watt motors (vs EU 250w) and where 20mph has been the cutoff speed in the majority of states for years.

Faster, more powerful e-bikes would have obvious benefits;

  1. Aligning cycle speeds with traffic speeds on the increasing number of 20mph urban roads, obviating speed inconsistencies and the need for overtaking.
  2. Enabling longer Active Travel journeys to be realistically undertaken by e-bike.
  3. More power means more capacity for load and passenger haulage, improving e-bikes as a car and van alternative for suitable journeys/duties.

2. Why might I think of using an e-bike? What advantages do they have? 

Convenience: E-biking is a great Active Travel option in hilly, traffic choked cities like Sheffield. Here they achieve good average speeds as you are not slowed down by hills. On e-bikes, urban journeys can be quicker door to door than other transport options.

Confidence: E-bike assistance gives you more confidence on the road, having the power and presence to be more part of the traffic flow. E-bike users notice that even the odd bout of ‘weather’ doesn’t feel as discouraging as it usually does.

Better Route Choices: E-bike power flattens hills and shrinks distances, giving you wider route choices. You can choose to avoid busy polluted main routes and streets whenever you wish, regardless of distance and terrain. You will be pleasantly surprised at how much of your journey in and around your area and the city can be done on dedicated cycle routes and lanes, or via parks and quiet back roads you may currently be unaware of. This minimises the time you spend on or near traffic choked roads and rat runs.

NB: The use of Cycle lanes is not mandatory in the UK, rather it is a choice if the cycle lane is convenient, safe to use and suits your needs, but do remember that you are a road user just like any other, so as long as it is safe to do so, cycle within the law and in accordance with the specific rules for cyclists in the Highway code .This will keep you and other road users safer and better tempered.

Health: Statistically e-biking helps you live longer and with better health due to the gentle cardiac exercise. Research says you breathe in less pollution cycling in traffic than when sitting in a vehicle.

You can carry lots of stuff – and even your kids to school! We are starting to see UK parents get the continental habit of cycling to school with their children. They know that they both gain the health benefits, and are one less polluting car queuing up to park near the school. They will either cycle with them, or increasingly. seat them on or in their purpose built Cargo type bike. This they also use as general urban transport for a big shop or stuff that would previously have needed a car boot. (eg  Tern GSD ,  Riese + Muller Multicharger Urban Arrow or similar ‘box in front’ style cargo bikes such as these at the Dutch Cargo Bike shop or by Cube which safely and legally carry two young children).

Equality: e-bikes can help many people have the legs, lungs and confidence to get around their neighbourhood under our own steam, be they previous bike users or not. They lend regular bike users a bit of assistance to help deal with the challenges arising with age or injury, thus ensuring they can still do that cycle tour or keep up with fellow riders on the Derbyshire day ride.

For some people, having assistance might simply mean the difference between being able to use a bike or not.  I have a previously non cycling friend with a chronic back condition and asthma who recently achieved a 100 mile e-bike ride on his local lanes and trails!

Fun: Often those who would not or cannot normally cycle any significant distance on an unassisted bike now choose e-bikes for recreational rides up to 50 miles or more. They love the feeling of easily getting out and exploring their local roads, cycle trails and bridleways, and maybe even keeping up with their children and grandchildren!

You don’t need to look like a ‘cyclist’:  With electric assistance, you can choose to wear everyday clothing, plus waterproofs if needed, and arrive at your destination in a relaxed, non-sweaty state.

E-bikes are cheap to run….  : After the initial outlay, the mile for mile cost of e-biking is favourable compared to other means of getting about. E-bikes can  carry you and any amount of shopping or stuff up to fifty miles or more, door to door, for just a few pence.

Should you wish to, you could use an e-bike to assist you on your journey from Lands End to John O groats and use just £1.50’s worth – yes, that’s one pound and fifty pence of mains electricity – in the process!

…and will Save the World!  Did you know that only 50% of vehicle pollution comes out of the exhaust pipe?

The other 50% is the toxic dust and microplastic particles that come off the brakes, clutch, tyres and the road surface itself? These are then wafted back up for you to inhale as the next vehicle passes and eventually washed to pollute the oceans. Electric vehicles (EV’s) will only rid us of the pollution from the exhaust, nothing else, and still take up a vehicle size footprint…

In contrast, e-bikes produce only a  fraction of these pollutants, and use only a fraction of the earth’s resources for their relatively tiny batteries. E-bike batteries weigh around 3kg, compared to 400 – 600kg (yes hundred) for an EV.

There is increasing interest in the benefits e-bikes bring to us and to the planet, and studies like this one and the  Shared Electric Bike Programme  which include a project in Rotherham are enlightening.

3. But what about the (high) cost? – how much should I pay, and how might I finance it?

Experience suggests that to get a basic e-bike for general but  lighter transport duties in and around hilly Sheffield you will need to spend a minimum of £1000.

However, to get an e-bike that will comfortably and reliably cope with heavier daily utility use you should spend £1500 upwards. Spend £2000 – £2500 for a machine that will have the power, gears and battery capacity for really relaxed everyday and utility useage around Sheffield and beyond.

Yes – that sounds a lot for ‘a bicycle’, but don’t switch off here – we really need now to be thinking of e-bikes in the same ‘transportation costings’ bracket as cars, buses, taxis etc, rather than relative to ‘normal’ (unassisted) bikes.

An e-bike replaces a car – not another conventional bicycle…

Just as with ordinary bikes, you should avoid cheaper ones. They tend to be underpowered, hard to ride, hard to get parts/service and (usually the electrics) will let you down and it will end up abandoned in the shed.

Well made, reliable models like the hub drive EBCO UCR-20 start around £999, however this will only be sufficiently powerful for the flatter routes around the city.

£1500 – £2000+ will buy you a more natural feeling and efficient Mid drive e-bike with high quality parts and equipment, and it will have more oomph for utility work around hilly Sheffield. This is particularly important if you are heavy yourself, and/or loading up with stuff.

Whilst day to day running costs are miniscule compared to a vehicle, this is a significant initial outlay, so maybe have a spin at a trail centre to see how an e-bike feels, or borrow one for a trial period through the Govt/Council funded Cycleboost scheme. Hire one from a local bike shop to see if it meets your needs (see list below), or or get together with family, friends or neighbours and buy shares in a ‘multi-user’ one.

If you decide to buy and want to spread the costs so as to afford a good model, check out dealers and retailers payment schemes (sometimes 0%)

Some organisations like cyclinguk  and britishcycling have discount agreements with retailers like Halfords.

Check if your employer has signed up one of  the Govt funded Cycle to Work (C2W) scheme providers. To get a bike (and accessories) on the scheme, your employer needs to have signed up to a provider. These include independent ‘middlemen’ like  Cycle Scheme , or retailers like Evans Cycles’ Ride to Work scheme (other retailers offer the scheme),  or now direct to the manufacturer, like the Electric Bike Access scheme just launched by the owners of Raleigh/Haibike and Lapierre brands. Employers can also sign up to schemes with longer payments times as well as high limits, such as the  greencommuteinitiative .

If you’re self-employed, you can make use of the scheme if you’re set up in a way which means you’re technically employed by your own limited company. Alternatively, you can buy the bike and claim the VAT back via the business.

The C2W scheme has worked really well for promoting the use of unpowered bikes, and many schemes have recently removed the old £1000 upper limit. This makes the purchase of a good quality e-bike or one of the more costly cargo style bikes a reality.

Note: C2W is a ‘Salary sacrifice’ scheme, meaning monthly payments are taken from your pay before tax is deducted, which benefits you to the tune of 32 – 42% reduction in the bikes RRP, depending which side of £50k salary you are. It also benefits your employer through reduced NI payments. One less attractive implication is that any benefits you have that might be salary based may be reduced proportionately in accordance with the amount being ‘sacrificed’ monthly as bike payment. For example this author was unexpectedly lucky enough to be offered early retirement during the payment period, however his final salary based pension was reduced proportionately, for ever ….

Full details on all this can be found in the very clear Gov doc here

Note, whilst the scheme also has the attraction of reducing the hassle of choosing and buying an e-bike to a minimum, if you are prepared to put in some time yourself you will have a wider choice, and you may well find a model to suit you at an overall discount similar to that this scheme offers……

4. Is it still a bicycle? 

Yes. Despite the welcome benefit of this assistance to waft you along, e-bikes are legally classed as bicycles, so you can use the many cycle-only cut throughs, cycle lanes, bus lanes and ‘shared use’ pavements to speed up your commute or shopping run, avoiding traffic queues and busy roads, and all with no parking hassles on arrival.

The UK legal rated ‘nominal’ or  ‘continuous power for one hour’ limit for a standard e-bike system (for public highway use) is 250 watts (peak power can be twice this or more – as much as a pro cyclist in fact!). The maximum assisted speed allowed is 15.5mph. More than 250 watts nominal power or 15.5mph assisted speed and it ceases to be legally classed as a bicycle and effectively becomes a moped, requiring a relevant licence, vehicle registration, helmet wear, insurance etc. Penalties for illegal acts committed on such a bike would then apply to your vehicle licence!

In practice, all e-bikes sold by mainstream UK retailers for use on the public highway are legal, just be careful to check there has been no aftermarket power or speed modifications if buying a used bike. If buying a bike or a DIY system via the internet check that they meet legal requirements.

Speed or ‘S’ Pedelec e-bikes like this look the same as UK legal ones, but top out at 28mph due to more powerful motors and different gearing. You can buy one in the UK, but it needs to be registered/insured/taxed etc  just like a moped. Good article on this from e-bike tips here

Note: The one area where the UK deviates from the EU is in allowing the fitting of a ‘Throttle’. In both the UK and the EU a powered ‘’Walk’ function – up to 6km/h – is allowed. (And is sometimes very useful, like when walking the bike up ramps) but in the UK an e-bike may also be fitted with a press button or twist grip throttle, provided it only works when the pedals are being turned, and assistance cuts out at 15.5mph .

6. What type of e-bike will suit my needs (incl folding and cargo e-bikes)? 

For reliable everyday utility use, buy an e-bike  that is powerful, efficient, reliable, feels manageable and pleasant to ride and is equipped for your purposes. Utility e-bikes are relatively heavy at 18 – 25 kg, but pricier ones have a better quality frame and cycle parts, and so are easier and more pleasant to ride with the assistance switched off or using lower levels of assistance when you choose to.

Consider the best frame type for your purposes. The ‘trapeze’ (see Cube bikes recommended below) or deeper ‘step through’ frame types are a great Unisex option for hopping on and off around town. They generally offer more adjustability of saddle height  than the more usual ‘crossbar’ style frame, and so are better able to be adjusted for multiple users with different rider/saddle heights.

The deeper ‘Dutch style’ unisex step through models (sometimes archaically marketed as Womens’ models) tend to have higher set handlebars and a more upright sitting position giving good control and visibility – ideal for urban duties, whatever your gender!

Other bike types:

Cargo Bikes:

e-bike power is particularly suitable for shifting heavy or bulky stuff in the guise of  electrically assisted Cargo bikes. Cargo bikes present a flexible and green option for ‘last mile’  Urban deliveries and  delivery/hire schemes are sprouting up in the UK using Cargo bikes. One manufacturer is offering direct rent/buy  options to businesses.

Bosch have even produced an extra beefy motor  for cargo bike duties.

You can ferry the kids to school in comfort, or legally carry a passenger, besides a car boot full of stuff, or a Christmas tree…

A 60Kg or a (legal) passenger capacity ‘Cargo’ e-bike!!

Cargo models include the   Urban Arrow   and the amazing  Bullit.

Models that will also do passenger duties include the    Urban Arrow ,  Riese + Muller Multicharger , the Tern GSD or HSD , the kona ute and the cute Benno  bikes.

All these can be found locally at adifferentgear   (Previously Recycle bikes) here in Sheffield, where you also have the option to rent cargo bikes very reasonably for odd jobs, or to try them out before committing.

Our own small wheel ‘Butchers bike’ style Orbea ‘Katu’ is proving ideal for shared use by differing height riders who want a nimble, versatile ‘do it all’ urban e-bike. In most respects it replaces a small car, including carrying a small car boot sized pile of shopping!

Note: The Katu-E is now (2020) only available in its least powerful form, and therefore less suitable for serious work in hillier parts of Sheffield. However Cube do a similar model, the well reviewed  Compact Sport Hybrid – the Sport variant having sufficient oomph from the Bosch Performance motor and with 10 lowish gears (as opposed to the base 5 speed variant)

Folding bikes: 

Which folder you want depends on what it’s for – do you need lightweight multi modal personal transport, does it need to do everyday duties carrying stuff around utility/leisure duties as well?

However generally speaking, I guess people choosing a folding e-bike are more likely to be looking to use it as lightly laden personal transport rather than to perform heavy lifting utility type duties. As such, a less powerful model than the bikes generally described in this article may suffice.

Also, is it actually an access/storage space issue that is suggesting a folding or compact e-bike may be the best choice?….

The 20kg raleigh stow-e-way  is a reasonably capable and good value everyday folding bike. A friend of mine loves his and so did e-bike tips when they  tested it  . The same bike is also sold by Halfords as the Evo. (don’t forget UK cycling discount)

A major advantage is that it can be bought readily and locally, so you have backup if there are any warranty issues. It can be bought for £1275 or so, making for good value.

Going up the Raleigh ladder we have the well reviewed  motus kompact  – although you will want to test ride and ensure the combination of the entry level Active Line bosch motor and Nexus 7 speed gears suffice for your usual routes if they are hilly.

A high quality but heavy do anything everyday folder with good power for breezing the hillier parts of Sheffield would be the Tern Vektron  –  highly rated  here in its Q9 model form by e-bike tips, and available as the more powerful, wider geared S10 model which will prove easier in the hillier parts of Sheffield.

These are all around the 22kg mark, so hard work to carry far, but you may want to check out their various design formats that allow them to be wheeled when folded.

If leaping on and off busy  trains or lugging your bike up stairs etc you need lightness and especially compactness when folded, and nothing beats a Brompton if these attributes are needed.

Consider a genuine electric brompton but note that users have experienced issues, such as those noted by Brompton themselves , and some local users have had to have bikes replaced under warranty.

Here are great reviews comparing the electric and ‘acoustic’ Bromptons by Brilliant bikes

OR consider one of the Brompton conversions (but first buy your Brompton, and be sure it is a  6 speed model, and with the lower 44T chainring gearing option for hillier parts of Sheffield !)

See these 2 reports at electricbikereport 1  and electricbikereport2   for Brompton conversion reviews.

The latest light and efficient  cytronex brompton kit is well received at atob edition 127  and ebiketips

The sparticle  and nano Brompton conversions are solid well known performers. A friend loves his Nano converted Brommy, he and his wife both use it They value its ‘throttle’ function, and its use of everyday tool batteries.. He had his converted at popupbikes in Manchester

Woosh bikes have just released what looks like a well developed and good value Brompton conversion kit  that fits straight into the front wheel, with smaller batteries in the pipeline.

If money is no object, and maximum utility is not a priority, consider the  top end low weight folders from gocycle, reviewed here  but note this will be less Sheffield friendly as power doesn’t kick in till the bike reaches 4 mph – potentially problematic on a steep hill start.

or from hummingbird – reviewed here Note that you’d need to consider  the 4 speed model for hilly Sheffield, and even then try to test it’s suitability for your routes/purposes.

If you want a semi folding compact(ish) car replacement type bike and  need to move your kids or loads of stuff around consider the very clever (parks on its backside!) tern hsd-p9  (Not to be confused with the heftier GSD model)

Rent the Tern hsd to try it or buy it locally at adifferentgear

BUT If it’s space or storage issues you are trying to address and you just want a good non folding but compact bike consider a cube compact-hybrid sport, tested  here . It has clever ‘Speedlifter twist’ fold sideways handlebars – just add folding or detachable pedals and you’ve got a virtually 2 dimensional bike to park in a hallway, put on a vehicle bike rack, lay flat in a hatchback etc. eg:

Cheap n cheerful folding ones: Decathlon folding-pedals

OR personally i’d go for better quality ones that come off completely for a real slimline result: Tredz.co.uk/.MKS-XP-Ezy-Removable (but means you have to remember to take them with the bike – just hang them on the bars when you remove them!) – good anti theft measure too!

Both pairs have the legally required relectors fitted!

Electrically assisted Mountain bikes (e-mtb’s) are also now popular, and whilst most retail models are road legal (ie standard 250watt motors) more powerful machines can legally be used off road on ‘private land’.

Electrical assist is also well suited to Tandems, to Recumbents, and to those cycles adapted for users who have particular needs beyond a usual bike.

Note 1: Bear in mind where you are planning to use and keep the bike. Not everyone will be able to lift a heavier e-bike model plus accessories up steps/on to trains etc. If for example if you are likely to be putting your e-bike on a train as part of a tour you may want to give serious thought to getting one of the lighter models.

Note 2: Be aware that the few remaining older style e-bikes with batteries mounted between the seat post and the back wheel are a bit longer overall. With these storage or using dedicated train spaces and lifts etc can be an issue.

7. Lighter weight e-bikes:

Not everyone needs or wants an e-bike just to do everyday utility duties, and an increasing number of manufacturers are offering much lighter weight  Road (‘racing’) and Gravel (road+off road capable) bikes with Drop handlebars, or more upright seated Urban and fast commute bikes.

These bikes weigh around 12 – 18kg or so in total, rather than the 20 – 25kg of full fat e-bikes, and are kitted out with differing contact points (saddles/handlebars etc) and different gears, wheels and tyres to suit their purpose – be that fast road use, exploring tracks and bridleways or urban/commuter use respectively.

These lighter models offer you the possibility of choosing to cycle with low levels of assistance or just ‘as and when needed’  rather than dialling in frequent and/or meatier assistance as you are likely to do on a heavier e-bike, so achieving greater assisted range than you might expect from their smaller, lighter batteries. All presently use either the innovative and strong (60Nm) Fazua removable ‘mid drive’ motor and battery system, or slightly less powerful (40Nm) Ebikemotion X35 fixed rear wheel ‘hub drive’ system.

Review of the Ebikemotion X35 M1 hub drive, clarifying its pros and cons  here  , and the Fazua here 

Examples employing the Mid drive Fazua system include the Boardman bikes range – great value and only 16 kg all up – so only 13kg ish if you opt to use it without the removeable motor and battery – models like the hybrid has fittings for mudguards, a luggage rack, has sturdy tyres, a good gear range and a removable battery for easy charging or using a second one to extend your range. Or check out the classy locally produced Forme Thorpe E Road .

Examples employing the Ebikemotion X35 drive system include the Orbea Gain range, the cannondale treadwell neo and the very high value ribblecycles range, offered in both Road and ? touring suitable  Gravel bike and hybrid versions. Note however that on the ebikemotion system the main battery is not removable,  the charger is small and compact so good to take with you, but on the other hand you’ll need to be somewhere where you can plug the whole bike in as you can’t remove the battery and take it inside to charge.

Either way, with their smaller, lighter motors and batteries and absence of motor ‘drag’ present on mid motors when the motor is off, these systems can more easily be ridden without power, or with lower levels of assistance, extending the range per charge. Such bikes will suit moderate riders looking to extend their mileage/time out on the bike, and may also better suit older experienced cyclists looking for less overall weight and a judicious level of assistance as and when required, or even those who prefer to be a little covert about their use of an electrically assisted bike!

Range wise, a local user reckons to comfortably get around 55 miles out of his Ebikemotion powered Orbea road bike on a hilly Derbyshire outing.

Another local notes that the same system on the Cannondale Treadwell makes for a nice light leisure oriented e-bike that feels great to ride on moderate terrain with assistance on or off, but that struggles to give sufficient support on significant hills, suggesting that in its current incarnation at least, it would make for hard work on a utility bike around Sheffield.

Need extra juice for longer rides with these small battery systems, and ? even goTouring?

On the Fazua system you can take a (1.38kg) spare battery along to swap out when needed.

On the X35 system, an additional  range-extender-battery  pack which tops up the fixed main battery may be taken along for a longer ride.

It is worth considering whether these bikes may be a good ‘e’ choice for touring, given that it will be more portable when using narrow cubicle style ‘hang up on a hook that won’t take larger tyres or wide handlebars’ train spaces, heaving it into B+B’s etc…..or even to carry/store at home if your storage solution is a tricky one….

(For a good example of a longer ride on this type of e-bike see Laura’s e-bike LeJog , incl a 120 mile day in 45mph headwinds!)

Otherwise go for a beefier but heavier road bike with stronger support and bigger batteries – something like the Bianchi impulso e road or Giant Road-E 

8. Which type of electric motor system is best for a utility bike in Sheffield – Hub motor (in one of the wheels) or a Mid motor (in the frame)? And how powerful does it need to be for my needs?

An e-bike consists of a bike with a fitted Battery, Controller and electric ‘engine’ – the Motor.

There are 2 main types of these;  either small electric motors in the front or rear wheels (Hub drive) and those with the electric motor positioned down in the frame and putting their power through the pedal axle as you pedal (Mid-drive). This type of drive is also called Chain, Centre or Crank drive. Mid-drives models are generally more expensive as the bike is specifically built around the motor.

To help you decide which is best for you, consider what you want the bike for and where you are going to use it.

Mid-Drive:

In our experience, and in the view of testers and users, the Mid-drive type, although more expensive, is generally more suitable for utility bikes being used in hilly areas. The electric motor drives through the bike’s gears as you pedal. This means that with the right gear selected the motor is kept running at its optimum speed. This uses the power more effectively and efficiently, particularly on steeper hills.

Our current e-bikes are the Mid-drive type, and we use them as everyday transport for short, often well-loaded utility journeys to work, the shops, the allotment and for social visits in hilly Sheffield.

Note that mid-drive motors offer varying degrees of ‘motor drag’ – that is because you are pedalling ‘via’ the motor, and so you are turning the internal cogs and widgets of the engine even when the assistance is switched off. Of course this is irrelevant when you are using the power, but it does mean you will find yourself having to make a bit more effort than on an unassisted bike if you are pedalling with the power off, ie over the 15.5mph legal assistance cut-off point, or if you have switched off to extend the range.

Manufacturers are reducing this resistance with each new iteration of motors, but it is a good idea to try riding any test bike with the power off to see how it feels if you plan to use it like this for any significant period.

Hub Drive: 

There are two types of hub motor. Geared and Gearless. The geared hub motor has planetary gears that step down the RPM of the motor to a much slower speed to drive the wheel.

These can be quite powerful, and may be fine for leisure and commute use around Sheffield.

The gearless hub motor directly connects to the wheel, driving it directly. This type is essentially ‘single geared’ and so as your own and the wheel’s speed drops on hills so does the motor power and efficiency. Fine for less arduous routes, but on longer climbs can become strained, inefficient and eventually overheat/cutout.

Hub drives broadly fall into two categories:  ‘Full time’ where the user may have the assistance switched on for sustained periods of time, more like a mid-motor user would. This type system will be relatively heavy, including a chunky battery of a similar capacity to a mid-motor system. The other is a more on demand ‘power-boost’ system brought into use less frequently and for shorter periods of time as and when conditions dictate, and so will have smaller and lighter components (motor/battery).

Good article on the difference between Mid-drive and Hub motors  here .

Note: Power (Torque) claims for Hub motors need to be treated with care: See ebikereviewer  hub-motor-review-and-comparison

How Powerful a motor should I go for? – You need a powerful enough motor to meet your needs and make for safe and relaxed around Sheffield.  In our experience in hilly Sheffield, a rider using an e-bike for relatively light duties like commuting and is not themselves very heavy will manage most gradients with a bit of effort using a mid drive system delivering a minimum of 40 Nm of torque (assistance).

However most riders, particularly those using the bike’s potential to carry loads in hilly areas, really will need a minimum of around 50 Nm.

If you plan to really load up, tow a trailer, or would just prefer a really relaxed ride where your journey involves proper Sheffield hills, 60Nm and upwards will serve you well.

(Nm is a measure of Torque, the assistance that helps you. It is the motor’s pulling/accelerating/climbing power, expressed in Newton metres – hence ‘Nm’.  Legal 250w e-bike Hub and Mid drive motors can produce varying levels of torque.  Hub drives produce around 30 – 60Nm, Crank drives 40Nm up to as much as 100Nm or more, similar to a Ford Fiesta! These levels are set by the manufacturer when the motor is built.)

Motor brands:

You will often come across the strong and reliable Bosch  range of Mid drive motors in its various latest (Generation 4) iterations. The basic ‘Active Line’ offers modest power (40Nm) for general duties and leisure in flatter areas, the Active Line+ a bit more oomph (50Nm)  for heavier/hillier utility use, and the Performance Line/Performance Line CX (65 and 75 Nm respectively) for heavy duty use/super relaxed riding in and around Sheffield.

Note that these Bosch motors have different starting characteristics (from a standstill).  For example Bosch describe the basic Active Line’s starting characteristics as ‘Harmonius’ which in practice means very gentle, and this can be an issue when trying to set off on a Sheffield hill, particularly if you are loaded.

The two Bosch Performance Line motors (Performance Line and Performance line CX) offer two distinct advantages  over the less powerful Active and Active+Line variants for users in hilly Sheffield, or indeed out in such as the Peak district.

First is the aforementioned confidence inspiring alacrity as you set off, thanks to the ‘Sporty’ start up algorithm (but still retaining full and nuanced control) and the second is the clever variable support level algorithm embedded in the ‘Sport’ assistance setting. (This algorithm is also called the ’emtb’ setting, it and ‘sport’ are one and the same setting.)

This algorithm automatically supplies variable assistance levels depending on your pedal pressure, from the ‘Tour’ level right up to the ‘Turbo’ level.

In practice this means that you can leave it in this setting and either pootle along with just light pedal pressures, or, if circumstances or the mood takes you, pedal harder and be given full power for the maneuver in hand (or hill, headwind etc)

So less distraction choosing levels, and easier and safer startoffs!

Excellent and comprehensive overview of the latest (4th Generation) Bosch range of systems by Cyclerepublic here

Shimano offer similarly rated and very efficient/reliable motors – currently for urban/tour use the e5000 (40Nm), e6000 (50Nm) and e61000 (60Nm), and for MTB’s the e7000 (60Nm) and e8000 (70Nm), however you might want to check if the slight delay on pressing the pedals on the e6100 before the power comes in that one reviewer noted suits you.

Giant utilize the proven Yamaha motor in both 60Nm and 80Nm formats to suit their urban and trekking style bikes, although the utility focussed  ‘Entour’ models have the high mounted battery, and it appears you need to buy the premium ‘DailytourE+1’ model to get neccessary 8 hub gears for Sheffield.

Brose,TranzX and Bafang Crank drive motors are all capable and reliable.

e-bike tips have a good article comparing the major motor systems here , and Tredz bikes offer a good motor overview here .

These mid motors are found in premium models, along with high quality, reliable cycle parts, and all variants of 50Nm or more will be suitable for heavy duty/hilly use. Shimano even offer Di2 electronic gear operation as they try to woo a whole new cycle public.

Convert your own bike?

There are moderately strong mid-drive kits to convert your own bike, e.g Bafang or Tongsheng motor powered kits from such as the well regarded  Woosh bikes. Whilst relatively inexpensive and capable these won’t offer quite the same experience of integration as the major systems, and the electrics may need good care to remain reliable.

Good value hub-drive kits are available from Woosh bikes and locally from ebikenow

(The author has just fitted a Whoosh bikes supplied Tongsheng 48V 250W TSDZ2 torque sensing mid drive kit to a friend’s MTB, and initial experience is very good.)

The excellent lightweight and reliable  Cytronex system features a more on demand ‘power-boost’ facility, rather than full time power, and will be well suited to converting more nimble commuting and leisure cycles, including the road bike tested by e-bike tips here

Note: Although often assumed, in real life there seems to be no real gain from the odd model such as the Elby that ‘regenerates’ electric as you freewheel, all of which are Hub drive anyway.

9. But might it run away with me?

No – A good quality e-bike leaves you in control at all times – you choose how much assistance you want (if any) before you even start pedalling, and it only starts to help when you pedal, and even then sensors mean that assistance is only added in proportion to how firmly you push on the pedals.

Assistance stops as soon as you stop pushing the pedals or apply the brakes, and you can alter how much it helps you pedal using the handlebar control whenever you want to, even on the move.

That said, it is however sensible to take some time away from busy areas to familiarise yourself with the assistance that e-bikes offer you, and local groups like Pedalready offer introductory courses to help you find out how to ride an e-bike to best effect.

10. What sort of gears do I need, and how should I use them on an e-bike?

Like normal bikes, e-bikes either have enclosed low maintenance ‘Hub’ type gears in the back wheel (handy because you can change gears at a standstill) or open derailleur gears. Cheaper bikes have 7 speeds, up to 11 or more expensive models. With the exception of the Yamaha motor, they all have just a single front chainwheel, as the electrical assistance obviates the need for lots of gears.

Both gear types are fine if properly serviced, but either way a decent range of gears with a reasonably low first gear is needed in hilly areas.

So that is at least 8 gears for a Derailleur model, and minimum 8 for a hub geared model.

Interesting comparison of the gear types here

As regards Derailleur gears, 8 and 9 speed geared bikes really need an 11-34 tooth range cassette (rear gear cluster) as a minimum for hilly Sheffield use, and an 11-36 tooth cassette will make life considerably easier. 10 and 11 speed models can offer a more ideal 11-42 tooth range, or even 11-46 for a really low 1st gear to tackle stupidly steep hills in comfort.

Hub gear wise Shimano ‘Nexus’ 8 speed is ok for Sheff, but the 7 speed will be hard work, offering a 244% gearing range, equivalent to an 11-27 tooth 7-speed (cog) cassette. Thus with a typical chainring and rear hub sprocket combination of 40/19 the bottom gear is a high 36 inches, enough only for modestly hilly terrain, and the top is a nicely functional 88 inches.  The Nexus Inter-8 hub has all the same benefits but with an extra gear for a wider 307% range, equivalent to an 11-34 cassette, so better for hillier terrain, although some of the gear steps are a little wider as a result. The same 40/19 ratio gives a bottom gear of 30 inches and a top of 92 inches. With rear sprockets of up to a max of 22 teeth fitted to the hub 1st gear can be made as low as 26 inches, great for steeper hill territory. (thanks to Edinburgh cycles for those details.)

Shimano’s ‘Alfine’ 8 speed  hub is the premium option – same gearing as the Nexus but stronger for e-bike use and a more user friendly trigger action. (An Alfine 11 speed is – rarely – also available on a few expensive models.)

It is important to use the gears sympathetically and change down to lower gears when loaded, on hills or cycling against a headwind. This keeps your legs working at a reasonable lick, reducing strain on the motor, just as you would on an unassisted bike when you are making life easier for your own leg/lung ‘motor’.

This makes  the most of the battery power and maximises the mileage available from each charge.

11. What sort of batteries do e-bikes have? – How far will it take me?

(Note that larger capacity (Wh) batteries only mean longer range, not more power or speed!)

e-bike’s Lithium-Ion batteries come in different sizes. Their size or capacity, and so how far they can take you, is expressed in Watt Hours (Wh), arrived at by multiplying the more usual 36 volt electric motor x the number of Amp hours (Ah) the battery holds. So for example a 36 volt motor with a 10Ah battery makes for a 360Wh battery – ie: 36(v)x10(Ah) = 360Wh.

You consume around 5 – 20 of the batteries watts Wh for every mile you are cycling with power. Factors like your own weight, the weight you are carrying, how well maintained your bike is (especially the tyres being properly inflated), hills, wind direction and speed will all make a significant difference to the level of assistance you choose to select and therefore the amount of battery power you use and how far it will take you.

(You choosing to pedal vigorously at energy hungry moments like accelerating or hill climbing will help increase the range nicely.).

250Wh, 300Wh, 400Wh  and 500Wh batteries are the most common sizes, and even bigger ones are becoming available.

Batteries are increasingly becoming ‘hidden’ by integrating them into the frame to a greater or lesser extent.

So a battery will provide you with power for around 20 to 50+ miles, depending on its size, the assistance level chosen and how willing you are to cycle with the power off or on a low setting for the easier parts of the journey, thus eking out the battery.

Bosch have a helpful ‘Range assistant’ here but it’s a bit optimistic for Sheffield’s hillier routes! You can halve these predicted figures if you are heavy and/or loaded.

Battery warranties/eventual life expectancies are based on the overall number of charging cycles performed. They also deteriorate with age and use (giving fewer miles per charge) and are expensive to buy as an aftermarket purchase.(Bosch batteries say the cells they use will still have a capacity of at least 60% after two years or 500 charge cycles – depending on which happens first, and could give usable service for as long as 10 years.)

Accordingly it makes sense to go for the largest one you can at the time of purchase (say a 400wh rather than a 300wh, or a 500wh if possible.)

Mostly this means buying a more expensive model of a given range, or you may be able to negotiate a battery uplift on purchase.

Good overview re batteries from Cycling UK here and from also from electricbikereport

12. How do I charge and take care of my battery?

Charging is via the portable mains charger and cable specifically supplied for your battery and is straightforward, just like your phone.

The time taken varies, depending on the power (number of Amps) of the charger, and ranges from 4 – 6 hrs for a full charge, but the good news is these batteries take charge fastest from low, so are 50-80% charged quite quickly if you need a top up. Most batteries can be charged on or off the bike, but charge best at around room temperature.

They will give their best if used and charged regularly, prefer to be working at between 1/4 to 3/4 of their capacity most of the time, and don’t like to be either flattened or left on charge for long once full.

If yours is going to be out of use for a good time the advice is to store it somewhere cool at around 1/2 charge and top it up just a little up every few weeks.

They are temperature sensitive, preferring to be parked in the shade rather than full sun if possible, and must never be allowed to freeze. (Something to bear in mind if your bike lives in a shed or parked out overnight anytime) Range drops with lower temperatures, so you might consider buying your battery a cosy Neoprene Jacket to maximize the range in colder weather (good for absorbing knocks too)

Lithium batteries, particularly cheaper ones, can pack up after a year or two at worst if misused (that includes not being used and left uncharged). The more expensive mainstream ones fitted to good quality e-bikes should last for at least 5 years or longer if used fairly frequently and kept reasonably well charged, but all will gradually lose their capacity and therefore range as they are used and as they age.

If your battery is getting old and tired it may be worth checking out a re-cell from such as https://ebikebatteries.co.uk/

13. What Accessories do I need?

Actually in our view these are essentials: Go for a bike all kitted out with a rear pannier rack, mudguards, a strong centre or side stand and ideally with good fitted LED lights, powered by the main power battery or sometimes a front wheel dynamo. If these items are absent on your chosen model get some fitted at purchase, and get a pannier or two to go on the rear rack to make carrying stuff convenient, much safer than in a backpack.

14. How do I keep it secure?

This is an issue whatever we ride, but personally I try to hold with the view that, although it is my primary means of transport, it is just a bike, to be used whenever, and just locked up in such a manner that it really is too much trouble/risk to nick! That said, and whilst I haven’t checked the statistics on this, I suspect it may be worth considering what sort of e-bike you use in riskier areas like town centres.

I think it is pretty evident that thieves, presented with a parked ‘boring’ Utility bike, and a sexy e-mtb, will go for the latter, not least as it is possibly easier to sell on.

At the end of the day ours are insured on our house policy – other stand alone ones like ETA are available – might sound expensive but it is effectively my ‘car’ so what would I have to pay to insure that against theft?

I’m a big fan of the modern incarnation of the Frame or ‘nurses lock’ – the frame mounted lock that basically puts a bar through the wheel. These are standard on some models, and can be retrofitted if not. Choose one that has a plug in chain option and get a chain to suit – quick, flexible and convenient for every shop stop and a good start for longer stops, and given my cargo style bike and customary pannier contents weigh in at about 30kg  it would be difficult to waltz off with if one wheel is locked.

Something like the AXA-defender-rl-frame-lock and AXA-plug-in-chain-lock – buy them together at Decathlon:Defender-bike-frame-lock and Plug-in-chain-bike-lock-for-the-defender-frame-lock  (Also available at
