The cult of cycling is strong (I admit I'm a fully paid up member), which begs the question: how will it react if a new breed of cyclists comes along with artificial power in its pedals? What happens when bikes get plugged in?
Just like riding a bike

While some e-bikes have a throttle that works like a motorbike, most use torque sensors to assist your movement. This means that once you start pedalling, the motor kicks in and helps you on your way. Pedal harder and it pushes harder; stop pedalling altogether and the motor switches off. There's nothing 'new' to learn here, your exertion is simply accentuated.
As a result, riding an e-bike for the first time feels bizarre for about 30 seconds, and then it becomes second nature. It really is just like riding a bike from the Telegraph, by Jonny Cooper
