A powertrain for an electric bicycle has: an electric motor; a motor gear driven by the electric motor; a crankshaft adapted for connecting to crank arms; an input shaft having first and second end portions, the second end portion driven by the crankshaft; an input gear connected to the first end portion and being driven by the motor gear, the input gear driving the input shaft; at least one first gear mounted to the input shaft; an output shaft; at least one second gear mounted to the output shaft and being driven by the at least one first gear; a drive sprocket driven by the output shaft; and a torque sensor disposed between the second end portion and the at least one first gear for sensing torque applied to the input shaft. The electric motor is controlled based at least in part on torque sensed by the torque sensor.
