Abstract:
A number of variations may include a product comprising: an electric cycle powertrain comprising: a motor; at least one gear set operatively connected to the motor; a chain ring operatively connected to the at least one gear set and a chain; a rear sprocket operatively connected to the chain ring and a rear hub; a crank operatively connected to the chain ring and a first pedal assembly and a second pedal assembly; at least one controller and at least one sensor, wherein the at least one controller is constructed and arranged to process one or more signals from the at least one sensor to apply a torque to the motor to compensate for inertial and spin loss associated with the electric cycle powertrain.
