Thinking of making the switch to an e-bike?

Whether or not you already cycle, there are many reasons why you might want to buy an e-bike.

E-bikes are cheaper to buy, run and maintain than cars. Research suggests e-bike owners use their cars less, and some go on to get rid of their car completely.

Electric bikes make carrying stuff easier and dramatically extend most people's riding range. On top of that, they're masses of fun.

Whatever the reason for your interest in battery-assisted bikes, here's a list of FAQs:

How much should I spend on an e-bike?

Just like conventional bicycles, e-bikes cost from as little as £300. If you want to make a real saving, you can buy an e-bike direct from the manufacturer. However, it means no bricks-and-mortar dealership to turn to in the event of problems. As a result, most people will want the reassurance offered by a UK-based distributer. If you buy from a domestic outlet, count on spending from £1,200. As with non-electric bikes, look out for sale prices as dealers clear stock to make way for new models.

How heavy is an e-bike?

E-bikes come in all shapes and sizes. For example, the Brompton electric folding bicycle tips the scales at 15.6kg. By contrast, the Babboe Curve electric cargo trike weighs in at 73kg. There's no escaping the fact that e-bikes are heavier than conventional bicycles. However, electric bikes aren't intended to be ridden without assistance from the electric motor, so you're unlikely to notice the extra weight unless or until you have to carry it up stairs. Or you break down.

Luckily, you can get breakdown cover for e-bikes and trikes for only £24 per year.

How fast is an e-bike?

An e-bike motor will help you reach just over 15mph. This doesn't mean you can't faster - it's just your legs will need to work harder. If your e-bike motor is more powerful, in the eyes of the law it's a motorcycle (see below).

Which e-bikes are legal?

UK e-bike law might be easier to navigate if there was a catchy name for road-legal electric bicycles. As it is, the officially recognised acronym EAPC (electric assisted pedal cycle) hardly trips off the tongue. In simple terms, if your cycle has pedals and an electric motor of no more than 250 watts that cuts out once you’re travelling at 15.5mph (25 km/h), then in the eyes of UK law it’s a bicycle, or to be more precise, an EAPC (electrically assisted pedal cycle). It's important to remember that the 250W figure refers to the power of the motor and not the battery.

An e-bike with a motor over 250W, or that doesn't cut out automatically at 15.5mph, is a motorcycle. Some of these e-bikes might look indistinguishable from the EAPCs described above, but their higher performance is usually an obvious giveaway. People have been known to fit official-looking 250W stickers to their over-powered e-bikes, but the police are wise to this. When there's doubt, the e-bike can be confiscated at the roadside and sent for testing.

How much are e-bike servicing costs?

In general, e-bike motors don't need servicing. For example, the Bosch motors fitted to many models of e-bike are sealed for life and if kept dry will do over 50,000 miles (80,000km) without problem. You might find the heavier weight of the bike means you go through a few more consumable items. Luckily, brake pads and tyres are relatively inexpensive items to replace.

How much does it cost to recharge an e-bike?

No simple answer to this one as there are multiple factors to consider such your electricity rate, battery size and its age.

Take your e-bike's battery capacity (Wh) divide by 1,000 to get the kWh (kilowatt hours). If you multiply this figure by the kWh rate you're paying your electricity supplier you'll get the price of a full charge. Assuming the battery is completely empty and you give it a full charge.

For example, if the rate you pay is £0.27 per kWh and your battery is rated at 500Wh, it will cost a tad over 13p for a full charge.

What if my e-bike breaks down?

We launched the UK's first Cycle Rescue service 30 years ago and include it with every cycle insurance policy of ours. Alternatively, we sell it as a standalone service for £24 per year. If your e-bike or electric cargo bike suffers a puncture, mechanical issue, or even a flat battery, we can send a recovery lorry to rescue you.

How long does an e-bike battery last?

E-bikes use the same type of battery as smartphones and laptops so you'll know from experience that as they age, they need to be charged more frequently. In terms of how long a single charge lasts, it depends on the capacity of the battery, how it's being used and its condition.

Is there a fire risk with e-bike batteries?

According to the London Fire Brigade: “Many of the fires we are seeing involve batteries which have been sourced on the internet, which may not meet the correct safety standards. We know that lithium-ion batteries are susceptible to failure if incorrect chargers are used, so it’s important to always use the correct charger for the product and buy an official one from a reputable seller.”

Only buy aftermarket lithium ion batteries from a reputable supplier and always use the correct charger to minimise the risk of the battery overheating.

How far can I ride with an e-bike?

The range of your e-bike on a single charge will vary according to many factors - not least how much assistance from the motor you use. In other words, you can conserve your battery and thereby extend your range by doing more of the pedalling yourself. The most powerful e-bike batteries can deliver as much as 80 miles of range.

Do I need insurance for my e-bike?

E-bikes are expensive to replace and attractive to thieves. Every ETA insurance policy includes theft & accidental cover, no-quibble battery theft cover and Cycle Rescue breakdown cover plus many other benefits. Read a full list of everything we include as standard.

Who can ride an e-bike in the UK?

You don’t need a licence, vehicle tax or insurance to ride an electric bicycle, but must be over 14 years old.

Will I still get exercise?

E-bikes allow you to choose the level of assistance from the motor so it's up to you how much effort you put in. It's not like riding a motorcycle - you'll still have to pedal.

Are e-bikes more likely to be stolen?

Thieves target e-bikes so it's a good idea to protect yourself with a good cycle insurance policy.

What happens if I get a flat battery?

We launched the UK's first Cycle Rescue service 30 years ago and include it with every cycle insurance policy of ours. Alternatively, we sell it as a standalone service for £24 per year. If your e-bike or electric cargo bike suffers a puncture, mechanical issue, or even a flat battery, we can send a recovery lorry to rescue you.

Can I turn my bicycle into an e-bike?

Yes. For almost as long as there have been bicycles, people have been adding motorised assistance. For example, the French Michaux-Perreaux steam velocipede of 1868 pre-dates the first safety bicycle by almost two decades.

Modern electric motors and lithium ion batteries have made motorising your bicycle much easier.

Many riders who want to retrofit an electric motor opt for kits made by Bafang. The kits are available with either hub or mid-drive motors are good value for and easy to fit. However, be aware that many are too powerful to comply with UK law.
