Abstract
A low center of gravity scooter using a standard bicycle pedal system for initial forward motion. The front wheel of the scooter is pivotally mounted to a frame and includes an upwardly extended shaft supporting a chopper style handlebar, for steering. A rear wheel pedal system including a pedal crank, sprocket, and chain drive, mounted to the scooter frame. The rear wheel assembly includes a sprocket with free wheeling chain drive hub for forward motion and free wheel coasting. This unique Scooter-Bike uses a bicycle pedal system to provide forward motion on a stand-up scooter vehicle that can be ridden as a bicycle until sufficient speed is attained. The rider then can maneuver it in the stand-up position as a very maneuverable scooter.
Claims2
A Scooter-Bike, compromising in combination:
- a. A scooter frame assembly having a large flat standing platform for upright drive capability, a front fork assembly, and rear frame extenders, supporting the rear wheel assembly. Refer to FIGS. 1-5.
- b. A bike pedal system mounted rearward on the scooter frame, consisting of left and right pedals and cranks, with chain sprocket.
- c. A front bike seat mounted 10 degrees rearward of vertical above the pedal system, with an adjustable height provision.
- d. A front wheel and steering system, that includes an extender tube connecting the chopper style handle bars to the lower wheel fork.
- e. A rear wheel system consisting of a drive chain sprocket, free wheeling hub, mounted to the rear scooter frame extenders.
- f. A front and rear caliper braking system with braking control levers mounted on the left and right ends of the handle bars.
A Scooter-Bike, comprising of the following combination of design features:
- a. A frame design constructed of electrically welded steel tubing for strength and weight stability. Refer to FIGS. 1-3.
- b. A frame design with a twin tubing neck, encompassing a sheet steel center web, connecting the steering (head set tube) to the base frame, for strength and stability.
- c. A low center of gravity rounded rectangular platform base constructed of steel tubing, connected to the neck from three points (center, left, right) and the rear frame extenders.
- d. The platform base is constructed of sheet aluminum or plastic and is attached to the top of the tubular steel frame. The platform provides a large surface to operate the vehicle from.
- e. The large wide base platform also enables the operator to apply downward pressure at rear or front, left or right, for fast and unique scooter maneuverability and tricks.
- f. A twelve inch front and rear wheel with high speed steel bearings and pneumatic tires, steel spokes and wheels, provide for low rolling resistance and high speed.
- g. A front fork and handlebar design consisting of a long handle bar extender tube for operation when standing, chopper style handle bars for a unique feel and amplified steering operation while standing or sitting.
- h. A high compression seat with adjustable height provisions mounted slightly rearward of the pedal assembly, toward the rear wheel, to allow the operator's body weight to be over the rear wheel, thus enabling the operator to more easily lift the front wheel for scooter tricks. The seat is mounted on a strong steel tubular shaft with stabilizer bars welded to the rear frame assembly.
- i. A pedal, crank and drive sprocket mechanism mounted directly to the scooter base frame.
- j. A free wheeling rear sprocket is used for very low rolling resistance.
- k. A front and rear caliper breaking system is used with left and right hand grips mounted to the handle bar, thus providing an efficient breaking system.
- l. A single action kick stand is used, mounted under the left side of the scooter platform for vertical support when parked. This stand easily tucks away neatly under the base platform when the scooter is ridden for ease of operation and safety.
