Our electric bikes are designed to be ridden under power all the time. Ideally, they are 50/50 pedal assist bikes. You do half the work. With the system switched ON when you pedal off the rotation sensor behind the chain wheel switches the motor on so you go faster and more easily than if you are just pedalling. On our 2014 bikes, the controller operating the pedal assist also varies the power depending on how fast you pedal, which means you can either amble along or if you pedal fast you will get more assistance out of the motor.
