An automatic gear shift system is provided for an E-bicycle that maximizes the contribution of the electric motor assist of the bicycle while minimizing the instances in which the electric motor assist is invoked. A control system monitors several sensors and particularly the change in sensor data at discrete intervals. If the change in certain sensor data exceeds predetermined thresholds the control system directs an electronic shifting device to execute an upshift or downshift of the bicycle's gearing, as appropriate for the conditions. The control system also determines whether additional thresholds are exceeded, in which case the control system activated the electric motor to assist the rider.
