Bicycle trailers and bicycles with a bicycle trailer

摘要

The invention relates to a bicycle trailer (1), comprising a chassis (2) with at least one wheel (3), with a drive module (5) for driving the at least one wheel (3) and a control and regulating unit ( 7) are arranged to control the drive module (5), further comprising a coupling (4) for at least indirect attachment of the chassis (2) to a bicycle (15), the coupling (4) having a receptacle (8) which is used for this purpose is designed to at least partially receive a ball head (9) attached to the bicycle (15), the receptacle (8) being axially displaceable to a limited extent relative to the ball head (9), or vice versa, the receptacle (8) being a sensor system (10) for detecting the displacement of the ball head (9) relative to the receptacle (8), or vice versa, and wherein the control and regulation unit (7) controls the drive module (5) taking into account the sensor data of the sensor system (10) in such a way that an axial position the on assumption (8) is relative to the ball head (9) within a load-neutral area (11). The invention also relates to a bicycle carriage (14) with a bicycle (15) and a bicycle trailer (1) of the aforementioned type coupled to it.
