A motorcycle trailer that includes a box trailer bed. The motorcycle trailer also includes a hinged lift lid, the lift lid including aerodynamic curvature on the front top and rear top. The motorcycle trailer additionally includes at least one lid latch positioned and structured on the off-road side of the hinged lift lid for fastening and unfastening the hinged lift lid closed selectively and the hinged lift lid having lid curvature corresponding to the aerodynamic curvature of the front top and the aerodynamic curvature of the rear top of the box trailer bed. The motorcycle trailer also includes the box trailer bed being affixed to a trailer frame, a road-side wheel suspended from the roadway side of the trailer frame with a road-side spring member and an off-road-side wheel suspended from the off-road side of the trailer frame with an off-road-side spring member.

The invention relates to a trailer (2) for a bicycle (1), having a braking device acting on wheel(s) (4) of the trailer (2); a sensor device (12) which supplies a measured variable, which is a measure of an acceleration force acting on the trailer (2) via a tow bar (5); a controller (18) for controlling the braking device and that is configured to act on the braking device, depending on the measured variable determined by the sensor device (12), such that an inertial force of the trailer (2) generated in the pulling mode or during braking of the bicycle (1) is compensated for or is at least reduced; and a decoupling device (10; 410; 510) which is configured for the partial mechanical decoupling of a movement of the bicycle trailer (2) with respect to the bicycle (1) in the longitudinal direction of the bicycle trailer (L).

A tilt control system for a sidecar and a motorcycle. The tilt control system can include a main frame, a tilting frame, and an actuator. The actuator can be coupled to the main frame and to the tilting frame, and can be configured to control tilting of the tilting frame relative to the main frame. The tilt control system can include a sensor, and a controller in communication with the actuator and the sensor. The controller can be configured to determine an operating parameter (e.g., a pressure) based on sensor data received from the sensor, compare the operating parameter to a threshold criteria, and cause the actuator to control the orientation of the tilting frame relative to the main frame, based on the comparison of the operating parameter to the threshold criteria.
