Hi there, The U-750 is equipped with a torque sensor system. This means the pedal assist level is determined by how much force you apply to the pedals, rather than only relying on cadence or speed. The harder you pedal, the more assistance the motor provides, resulting in a more natural and responsive riding experience. Addmotor Tech see less
