Electric bikes explained: what they are and how they work

http://ift.tt/28JRIcZ

One bike trend that’s hard to ignore is electric bikes, also known as e-bikes. The promise of being able to rider further, faster, for longer appeals to many people, but how do e-bikes work? How fast can e-bikes go and what’s the legality of them? Here’s our guide.

E-bikes are winning lots of fans in Continental Europe, though the UK and USA are a little slower to catch on. That could be partly because of worries that it’s “not really cycling”, or simply confusion over how they work. Let’s dive in.

What is an e-bike?

Put simply, it’s an electric bike that will provide extra power when you’re pedalling. Most e-bikes lack a throttle and won’t assist you if you’re just coasting, so abandon the idea of zooming up hills without pedalling at all. Electric bikes are usually made from specific frames and components that are built to handle the extra stresses caused by heavier, more powerful drivetrains.

E-bike vs normal bike

So how do they compare? Well an e-bike is heavier, more expensive and more complex than a regular push bike. That can be a problem if you run out of battery far from home or need to lift it, as they often weigh more than 15kg (30lbs). That means you’ll struggle to push it up a hill without motorised assistance.

Want to get it repaired? The components are more expensive than those found on “normal” bikes, and bike shops won’t be able to help if it’s motor or battery-related. That means going back to the shop you bought it from, or else hoping that there’s a dealer nearby willing to help, and asking them to help with a warranty claim.
