In order to improve a wheel unit, in particular for a vehicle, comprising a wheel having a hub and a wheel rim which are connected to one another by spokes and are arranged for rotation about an axis of rotation, it is proposed that the wheel have connected thereto a disc unit arranged coaxially with respect to the axis of rotation, said disc unit carrying a brake ring for a disc brake and a sensor ring for detecting a rotary movement of the wheel unit.

A bicycle hub assembly includes a hub shell including a braking surface. A coaster brake shoe is accommodated in the hub shell and cooperates with the braking surface to generate braking force. A motor is accommodated in the hub shell and configured to be controlled for at least changing or maintaining a gear ratio.

A method for assisting a driver of a two-wheeled vehicle. The method includes sensing and evaluating a driving environment of the motorcycle as a function of a driving state of the motorcycle, especially an inclination of the motorcycle, in order to detect objects in the driving environment; determining a hazard potential as a function of the detected objects and the driving state; and warning the driver and/or triggering a driver assistance system and/or a vehicle safety system of the motorcycle as a function of the determined hazard potential.

A straddled vehicle includes a battery, a front wheel mounted on an axle, a motor including a stator and a rotor rotatable around the axle together with the front wheel, the motor being supplied with electric power from the battery to generate motive power, and a front suspension supporting, in a cantilever manner, the axle being inserted through the front wheel and the motor.

A foldable cargo trike equipped with at least four drive train configurations and an advanced stability control system (herein referred to as the 'trike) is disclosed. A first embodiment features a frame-mounted drive motor with a mechanical differential for the rear two wheels. A second embodiment utilizes an electronic differential with dual, independently-controlled hub motors on each rear wheel. In this embodiment, each drive motor is dynamically-adjusted by artificial intelligence algorithms. These algorithms analyze user driving habits and enable the trike to adapt in real-time for improved performance and safety. These first two embodiments have an anti-tip braking system controlled by two front-mounted sensors to detect lateral tilt or roll conditions and automatically applying braking to prevent tipping. A third embodiment includes two, frame-mounted electric motors connected to each wheel. A fourth embodiment includes a frame-mounted, electric drive motor having a planetary gear set which mimics a conventional differential.
