This device is a reverse mechanism for a motorcycle with a sidecar. It is related to a motorcycle conversion assembly whereby the sidecar is outfitted with a mechanism to allow the motorcycle and sidecar combination apparatus to move in a rearward direction. The device is comprised of a retractable wheel, a drive system, a control mechanism, a battery power source and a structure to removably connect the drive and wheel to both the motorcycle and sidecar.

A convertible bicycle has separable front and rear wheel units. The convertible bicycle can operate in individual or in tandem mode as a tricycle unit. The rear wheel unit has a vertical interlocking gear which can interface with a frontal interlocking gear of the frontal wheel unit. The front wheel unit of an auxiliary bicycle can be detached and the remaining rear wheel unit attached to the rear wheel unit of another bicycle in order to form a tandem tricycle.

A bicycle carrier for towing a second bicycle behind a first bicycle is provided. A carrier base has carrier wheels and is adapted to carry a wheel of the second bicycle. The carrier base is articulated to arms at their ends remote from the rear hub of the first bicycle. Clamping means are provided for clamping the wheel of the second bicycle in place on the base. The base can be carried above a rear wheel of the first bicycle when the carrier is not in use. A passenger carrier for a bicycle includes a carrier base having wheels, and handlebars on a member attached to the carrier base and foldable with respect thereto. Side sections of the base are locatable within a footprint of the central section when the carrier is not in use.

A pet and human tricycle device is provided. The device is comprised of a tricycle comprised of a secondary frame. The secondary frame is comprised of a rotating belt that can be used as a manual treadmill for a pet to run alongside the user while the user pedals the tricycle. The pet can further be secured to the secondary frame during use. The device is self-propelled by the pet such that the pet can run at its own pace, and wherein rotation of the belt can be inhibited by the user as desired via at least one mechanism.
