Claim:
1. 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 and a rear hub; a crank operatively connected to the chain ring and a first pedal assembly and a second pedal assembly; and 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 estimate a first spin loss torque of the motor, a second spin loss torque of the at least one gear set, and an inertial torque of the motor and the at least one gear set, and summing the first spin loss torque of the motor, the second spin loss torque of the at least one gear set, and the inertial torque of the motor and the at least one gear set to apply a torque to the motor to compensate for the first spin loss torque of the motor, the second spin loss torque of the at least one gear set, and the inertial torque of the motor and the at least one gear set.
