Abstract: Electronic bicycles may communicate with each other to provide a communal biking experience to their riders. The electronic bicycles may collect rider data about their riders and may adjust the output parameters of the electronic bicycles based on the rider data. For example, the electronic bicycles may identify a weaker rider of the riders and may adjust the output parameters of the weaker rider's electronic bicycle to minimize a difference in the operation of the weaker rider's electronic bicycle and the stronger rider's electronic bicycle. Additionally, a parent rider may establish rider restrictions on an electronic bicycle ridden by a child.

Abstract: An electronic bicycle includes a torque control system that controls what torque is applied to wheels of the electronic bicycle by electronic hub motors. The torque control system may determine a torque to apply to the wheels based on user input signals. The torque control system also may detect when the wheels of the electronic bicycle are slipping, and adjust the torque to minimize the time that the wheel is slipping. Additionally, the torque control system may determine a coefficient of friction between the wheels and the ground and determine a maximum torque to apply to the wheels based on the coefficient of friction. Furthermore, when braking, the torque control system may determine whether torque is applied to the wheels by passive braking or by active braking.
