A bicycle includes a transmission having two switchable drives between a driver body on which rear sprockets are positioned and a wheel hub of a rear wheel. The bicycle has actuation elements for switching between drives and operating elements for operating the actuation elements. The bicycle includes only a single front sprocket. The actuation elements are embodied in an electrical version and the operating elements are electrically coupled to the actuation elements. By advantageously selecting the drives of the driver between the cassette housing and wheel hub, a front derailleur may be omitted. The driver allows operation with only little energy, since the chain need not be shifted. consequently, the actuation elements require little energy for changing the drive between the crank axle and the wheel hub of the bicycle, so that it is pre-eminently suitable for these actuation elements and their operation to be executed as an electrical version.

A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

An electronic device includes an artificial intelligence processor that is configured to generate second information for controlling an electric component including at least one of a drive unit that applies propulsion force to a human-powered vehicle, an electric adjustable seatpost, and an electric suspension in accordance with first information related to at least one of the human-powered vehicle, a rider of the human-powered vehicle, and an environment of the human-powered vehicle. The artificial intelligence processor changes a process for generating the second information in accordance with the first information and in accordance with an operation of a first operation unit for operating the at least one of the drive unit, the electric adjustable seatpost, and the electric suspension.
