The bicycle stand includes a first rod, a second rod, and a pivot structure. The first rod has a first end, a second end, and a first pivot portion between the first end and the second end. The second rod has a third end, a fourth end, and a second pivot portion between the third end and the fourth end. The pivot structure is pivotally connected to the first pivot portion and the second pivot portion so that the first rod is pivotally connected with the second rod and is able to pivot between a folding position and an opening position. The first rod and the second rod are X-shaped when the first rod and the second rod are at the opening position.

A scooter having a riding platform rotationally engaged to a front steering assembly is provided which significantly increases the ability of riders to perform tricks. The riding platform is rotationally engaged to the steering column which itself may be employed as a riding platform. An optional mechanism may be employed whereby the riding platform is rotated by a spin of the steering column with the handlebars. The scooter may also be equipped with skids to allow employment in the snow or on ice.

A mobile chair apparatus is described that comprises a drive assembly that preferably includes one or more moveable foot pedals, and drive wheels which rotate in response to rotation of the foot pedals by the mobile chair occupant, and a steering assembly which comprises two steering wheels and two armrests, wherein movement of just one armrest will translate into movement of both steering wheels, and wherein the drive assembly and the steering assembly concurrently enable the mobile chair occupant to propel and steer the mobile chair apparatus without assistance from another person.

An apparatus comprising a steering assembly, a drive assembly and a seat, the steering assembly comprises a first armrest connected to a first link arm, and a second armrest connected to a second link arm; a first tie rod connected to the first link arm and a second tie rod connected to the second link arm; a first steering block connected to the first tie rod and a second steering block connected to the second tie rod; a third tie rod interconnecting the first and second steering blocks; and a first and second steering wheel, and/or the drive assembly comprises a first and second drive wheel connected to an axle; a support shaft; foot pedals connected to a crank; a first chain connecting the crank to a gear hub; and a second chain connecting the gear hub to the axles or connecting components of the gear hub.

A blow molded toy cycle has a female bearing area with tapered and recess sections. A fork has a corresponding male bearing area that includes a tapered section and an annular protrusion section. A protrusion spaced at a distance from the annular protrusion extends from the shaft and has a surface to contact a top surface of the body to secure the fork when the male and female bearing areas are in contact. The fork has integrally formed tabs that to bend around an axle to form a bearing area for the axle that allows the axle to rotate within the fork. A blow molded pedal attaches to a section of the axle and has a series of ribs disposed between side sections to form a bearing area that allows the pedal to rotate around the axle. Two rear and one front wheels attach to the body and fork respectively.

A knee walker for use as a walking aid by disabled persons includes multiple wheels operably coupled to a frame and a steering assembly. A knee pad is supported by the frame intermediate front and rear wheels to support a user's bent knee and lower leg thereon. A suspension or shock absorbing assembly is disposed intermediate the knee rest pad and the frame. The knee walker is adjustable to accommodate users of varying sizes.

A drive mechanism for a vehicle is disclosed, said drive mechanism converting the reciprocating clockwise-counterclockwise motion of an input shaft into continuous rotation of an output shaft by means of two one-way clutches mechanically coupled to the input shaft and the output shaft, said one-way clutches having their power stroke in opposite directions of rotation. In an embodiment, said drive mechanism can be contained in a wheel hub and used for human-powered vehicles such as scooters, bicycles, wheelchairs, rollerskates, or other vehicles.

The bicycle stand includes a first rod, a second rod, and a pivot structure. The first rod has a first end, a second end, and a first pivot portion between the first end and the second end. The second rod has a third end, a fourth end, and a second pivot portion between the third end and the fourth end. The pivot structure is pivotally connected to the first pivot portion and the second pivot portion so that the first rod is pivotally connected with the second rod and is able to pivot between a folding position and an opening position. The first rod and the second rod are X-shaped when the first rod and the second rod are at the opening position.

A bicycle trailer brake includes an actuator forming a lever to actuate a brake. The actuator includes a mounting structure to couple the actuator to a bicycle or bicycle trailer and an input interface to receive an input force from a user. Upon attachment of the mounting structure to a bicycle or bicycle trailer, the input interface is positioned in a position behind and above a bicycle seat of a bicycle.

A multi-wheel-drive bicycle that includes a dual chain-and-sprocket drive mechanism mated with a two-opposite-sided paddle-main-sprocket system is provided. The multi-wheel-drive bicycle comprises a frame having first and second opposing sides and having front, rear and lower ends. A front wheel is rotatably mounted on the front end of the frame and a rear wheel is rotatably mounted on the rear end of the frame. The multi-wheel-drive bicycle further comprises a chain-driven rear-drive mechanism configured for transmitting rotational power to the rear wheel. The chain-driven rear-drive mechanism includes a rear main-drive sprocket disposed on the first side of the frame and located at the lower end of the frame. The multi-wheel-drive bicycle further comprises a chain-driven front-drive mechanism configured for transmitting rotational power to the front wheel. The chain-driven front-drive mechanism includes a front main-drive sprocket disposed on the second side of the frame being opposite of the first side of the frame and located at the lower end of the frame.
