Abstract: A plastic wheel assembly comprises a wheel, a hub assembly and a rim having two side walls adopted to hold a tire onto the rim. Preferably the wheel is made of two molded plastic wheel halves, each having a wheel flange extending outwardly from the circumference of the wheel and contacting the rim side walls. The rim fits between the wheel flanges and is preferably made of metal. The wheel halves are preferably riveted to the flanges on the hub assembly. A method of making the wheel assembly involves connecting the first wheel half to the rim and then connecting the second wheel half to the combination of the rim and first wheel half.

Abstract: A bicycle with simulated motorcycle parts includes a shroud attachable to the bicycle. The shroud has a center portion simulating a gas tank and a rear fender portion extending over the rear wheel. The shroud is configured to fit around the seat tube of the bicycle and preferably covers the top tube of the bicycle. In one embodiment, a fairing mounted in front of the handlebars simulates a fairing on a motorcycle. In another embodiment, chrome plated plastic parts are used to simulate a motorcycle engine and a sound system is included that replicates the sound of a motorcycle.

Abstract: A synchronous/asynchronous exercise machine is changeable between a synchronous exercise mode wherein a user's limbs, such as his legs, oppositely reciprocate, and an asynchronous exercise mode wherein the user's limbs move independently. The synchronous/asynchronous exercise machine may comprise a first movable element for accepting a user's limb, and a second movable element for accepting another limb. A load source against which the user can exercise may also be provided. A first drive belt operatively connects the first movable element to the load source, and a second drive belt operatively connects the second movable element to the load source. A quick change mechanism, which may be connected to the first movable element, is releasably engagable with the second drive belt for changing the synchronous/asynchronous exercise machine between the synchronous exercise mode and the asynchronous exercise mode.

Abstract: A bicycle with simulated motorcycle parts includes a shroud attachable to the bicycle. The shroud has a center portion simulating a gas tank and a rear fender portion extending over the rear wheel. The shroud is configured to fit around the seat tube of the bicycle and preferably completely covers the top tube of the bicycle. In one embodiment, a fairing mounted in front of the handlebars simulates a fairing on a motorcycle.

Abstract: A stationary exercise device has an elongated base frame, a seat supported by the base frame adjacent one end and a non-circular upright support adjacent the other end of the frame, and an exercise cycle assembly removably mounted on the support. The device preferably doubles as a rowing machine, the handle bars of the rowing machine serving a dual purpose.
