Yes. All of our electric bikes have pedal assist, not simply a throttle. They are fitted with a sensor behind the pedal arm which monitors the speed you are pedalling and applies the appropriate electric assistance to help push you along. The quicker you pedal, the faster the motor will turn. Once you reach 25kph the motor will keep you there while ever your pedals are rotating but if you ever want to go faster (what's the rush?!) the bike will rely 100% on good old leg power.
