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.

A two-wheeled cart is especially adapted for use as a game cart and may be easily towed by a conventional mountain bike. The cart has two interchangeable wheel positions. In the first wheel position the wheels are attached to the frame at opposite lateral sides of the cart and in this position the center of mass of a load carried on the bed of the cart is relatively low. In the second wheel position the wheels are aligned one in front of the other along the direction of travel as the cart is moved; in this position, the bed of the cart is raised to a relatively higher position than the position of the bed when the wheels are in the first wheel position so the center of mass of a load carried on the bed is relatively higher than when the wheels are in the first wheel position.

A drive module for a bicycle according to an aspect of the present invention, the drive module including a bicycle frame comprising a beam insertion hole into which a connecting beam is removably inserted, a main shaft rotatably provided on the bicycle frame, a rear wheel rotatably supported on the bicycle frame and configured to be rotated by rotational force from the main shaft, and a fork rotatably coupled to the bicycle frame.

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.

A multi-purpose cart includes a frame that defines a volume. At a bottom rear of the frame there are rear wheels disposed on opposite sides of the frame. One or more freely turning front wheels are located at the front of the frame. The bottom or floor of the frame is sloped downward from front to back to encourage placing items into the frame towards the back of the frame. A handle extension is provided at the rear of the cart that alternatively allows connection of a handle to facilitate pushing the multi-purpose cart by a person, as well as to connect to a towing assembly to allow the multi-purpose cart to be towed behind a bicycle and maintain the multi-purpose cart in a tilted position so that the rear wheels remain on the ground and the front wheels are raised above, and not touching the ground.

Apparatus and associated methods relate to a multi-axial offset side car. In an illustrative example, the side car may include a wheel with an axis of rotation along an axis adjacent to and between a front wheel axis of rotation of a vehicle and a rear wheel axis of rotation of the vehicle. Some embodiments may include a configuration where the axis of rotation of the wheel is centered below a center of a rear wheel axis of rotation of the vehicle. The sidecar frame may be coupled to a vehicle frame by at least three arms. The configuration of the placement of the axis of rotation of the side car wheel between the axis of rotation of the front and back wheel of the vehicle may advantageously prevent tipping and instability. Various embodiments may improve the suspension of the vehicle-side car system.
