A bicycle and method and bicycle assembly for a bicycle including a control device and at least one bicycle component whose operating state is variable during operation. An acoustic device with a sound converter is included for outputting information, controlled by the control device, on the operating state of the bicycle component by means of the acoustic device, and/or for capturing noises by means of the acoustic device and converting these to noise signals and utilizing them for controlling.

A method for controlling an electric motor as a drive motor of a bicycle. The method includes: a sensor-based detection of pushing of the bicycle by the user; acquiring an input of a user for activating the push-assistance operating mode, the acquisition taking place as a function of the detected pushing of the bicycle; and generating a motor torque for driving the bicycle in the push-assistance operating mode as a function of the detected pushing and the acquired input of the user.

The bike (10) comprises a frame provided with a front wheel (12) oriented by a handlebar, a saddle (39) and a crankset. The bike (10) further comprises two pivoting rear uprights (18, 19) each carrying a rear wheel (22, 23), the pivoting rear uprights being mounted by independent pivot links on the frame.

The crankset actuates two drive means (26, 27, 59, 60) independent of the rear wheels. The drive means of each rear wheel comprises a free wheel (59, 60). The drive means are configured such that, in a bend, only the rear wheel located on the inside of the bend is driven by the crankset, the rear wheel located on the outside of the bend freewheeling and not being driven by the crankset.

An electric assist vehicle is described, which may have a cargo area, a drivetrain including an external crankset and an electric motor, and a speed control system. The speed control system automatically limits the maximum operating speed of the vehicle based, at least in part, on a load mass (e.g., a gross weight) of the vehicle and/or the cargo area of the vehicle. Limiting the speed includes, for example, reducing the power of the electric motor and/or increasing a braking force on the vehicle.

This measurement device for measuring the angular velocity or acceleration of a two-wheel vehicle, is provided with a main detection unit which detects the three-axis angular velocity or three-axis acceleration, a support unit which can support the main detection unit on the body of the two-wheel vehicle, and a correction unit which cancels the lean of the body to the left and right in the main detection unit.

There is provided a method comprising receiving at a controller an input comprising a channel output from an input channel of a vehicle. The input is triggered by an operation of the vehicle by an operator. The input channel has a corresponding direct operational manifestation. The method also comprises comparing at the controller the input with a set of input patterns to select from the set of input patterns a target input pattern corresponding to the input, and generating at the controller a control output corresponding to the target input pattern. The control output is configured to cause in the vehicle a target operational manifestation different than the direct operational manifestation. Furthermore, the method comprises sending the control output from the controller to the vehicle.
