Abstract: An autonomous electronic bicycle comprises a frame, a wheel that can be powered by a first electronic motor, and a pedal assembly connected to a pedal motor. The pedal assembly is not mechanically connected to the wheel, but the autonomous electronic bicycle simulates a mechanical connection by powering the rear wheel proportional to the user's pedaling force. The autonomous electronic bicycle uses a virtual gear ratio based on the cadence of the rider, the current incline of the bicycle, and the current speed of the bicycle. The virtual gear ratio can be a ratio between a torque of the set of pedals and a torque of the wheel.

Abstract: An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. Similarly, the autonomous electronic bicycle can comprise a set of sensors used for balance. The autonomous electronic bicycle can use the balance sensors to determine a current state of the autonomous electronic bicycle and drive the electronic motors to balance the autonomous electronic bicycle and achieve a target pose of the autonomous electronic bicycle. A neural network can be trained to determine one or more motor outputs of the autonomous electronic bicycle based on the target pose and the current state.

Abstract: An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. The autonomous electronic bicycle can operate autonomously, traveling to a chosen destination. When operating autonomously the autonomous electronic bicycle can shift between a set of balance modes, including a mode used when moving and a mode used when stationary but balanced. To transition between modes, a transition sequence of control commands can be selected and used.

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.
