An introduction to e-bikes E-bikes are like normal bikes given super powers: you still pedal them, but they have an electric motor that gives you some extra help. It feels rather like having bionic legs: you can pull away from traffic lights quickly and easily tackle steep hills. That makes them brilliant for commuting and urban cycling, and a great choice for people who want to improve their fitness and haven’t been on a bike for years. What kind of e-bikes are there? Commuter bikes are all-rounders while MTBs are mountain bikes and road bikes are racing bikes. The former have big tyres and great suspension, while the latter use super-light materials and aggressive geometry to achieve high speeds. Cargo bikes are for carrying loads that are too big for panniers or a backpack, and usually have bigger tyres and better brakes. Cube Cargo 2021, £4,599 from Cube.eu
How do I get the right e-bike size? E-bike sizes are usually expressed as S, M, L and XL. Small bikes are generally suitable for riders up to 5’5” while XL bikes are designed for six footers and above. Some e-bikes have very adjustable seats and handlebars that enable them to skip between sizes. Is there more than one kind of e-bike motor? Crank drives connect directly to the bike chain, while hub drives sit in the wheel hub – usually the rear wheel. Crank drives are more energy efficient and feel more natural when pedalling but hub drives are usually much cheaper. What about gears? E-bikes come with the same kind of gear systems as ordinary bikes and the gears adjust how much pedalling is needed – in higher gears you pedal less because Volt Metro Folding Commuter Bike, £1,599 from Voltbikes.co.uk

you’re going faster. With e-bikes you’ll usually be able to control the assistance level the motor gives you. You might choose Turbo for fast pulling away from traffic lights but Eco (or equivalent) when on a relaxing country ride. How do I know what battery to choose? Most manufacturers provide a battery range estimate, or you can calculate the range by dividing the battery’s power by 20 – a battery with a 400Wh rating should give about 20 miles on full assist, which is when the electric motor is operating at full power. Most e-bikes have a little bike computer that shows battery charge and the range remaining before recharging is needed. When the battery runs out of power, your e-bike behaves like a normal bike, albeit a heavier one. Typical recharge time is three to four hours and batteries typically last for two to four years. How much should I spend? You can get perfectly decent e-bikes for around £500, or you can spend over £4,000 on a carbon road bike. The more you spend the lighter the bikes become and the better the hardware: where cheaper e-bikes are designed for everyday use, the most expensive e-bikes are serious bits of sporting equipment with matching price tags. Whatever you buy, make sure you also acquire a very good U-lock: sadly, all e-bikes are targets for bike thieves. Swifty E-Mountain Bike, £799 from Amazon.co.uk
