How do electric bikes work?

Modern electric bicycles are powered by a lithium long-life battery that runs an electric motor attached to either the wheel (hub motor) or the cranks (center drive/crank motor.) You engage the motor by simply pedalling, you can adjust how much push the motor will give you (usually 4 levels of power/push), if you stop pedalling the bike will slow done like a normal non electric bike. You have full control of how much or little power assistance you receive it’s that easy.
