Pedal Assist Torque Sensor Crank Shaft

With a torque sensor pedal assistance, there is sensor measuring how much force the rider is putting on the pedals. That allows you the rider to control the ebike motor with your legs; the harder you pedal the more power you get from the hub.

This kind of control can feel very slick and helps encourage more human power input, since you are made to ‘earn’ your motor power.
