What is pedal assist?

Pedal Assist automatically turns on the motor when you pedal. With pedal assist, you do not need to use a throttle to control the motor. 

There are two types of Pedal Assist: Cadence Sensor Type, which measures IF you are pedaling and a Torque Sensor Type, which measures HOW HARD you are pedaling. 

D-Class, X-Class ebikes are equipped with cadence sensors, while the other models have torque sensors.
