Front wheel drive vehicles, bicycles or motorized scooters, include an enclosed drive belt connected to provide power to the front wheel through a chain, where the vehicle is steered by way of a front fork extending outside and over the head tube of the frame, and methods of use thereof. Movable linkages, which may be belts, chains, or other linkages, provide power generated using pedals or a motor to the front wheel. The belts are preferably enclosed within the frame or the front fork to prevent interference or damage. A chain is preferably used to drive the front wheel. Having the front fork outside the head tube allows for the head tube to route the linkage from the frame to the front fork without interference by the steering connection to the front wheel, allowing for a full range of motion of the front wheel.

The vehicle of claim 6, wherein the plurality of movable linkages includes one or more belts in series with one or more chains. 10. The vehicle of claim 1, wherein the fixed head tube divides the front fork above the front wheel. 11. The vehicle of claim 1, wherein the front fork partially encloses the fixed head tube. 12. The vehicle of claim 1, further comprising: a motor coupled to the crank, wherein the vehicle is a motorized scooter. 13. A method of operating a vehicle, the method comprising: providing power to a crank operably coupled to a front wheel, wherein the crank is positioned between the front wheel and a back wheel;transferring the power through a moving linkage to the front wheel, wherein the moving linkage is at least partially enclosed within a frame between the crank and the front wheel, wherein the moving linkage is enclosed within a fixed head tube of the frame; andsteering the vehicle through a front fork that moves the front wheel, wherein the front fork passes around the fixed head tube above the front wheel. 14. The method of claim 13, wherein said steering the vehicle through the front fork that moves the front wheel, wherein the front fork passes around the fixed head tube above the front wheel comprises steering the vehicle through the front fork that moves the front wheel, wherein the front fork is connected around the fixed head tube with a plurality of connectors passing through holes in a plurality of plates. 15. The method of claim 13, wherein said steering the vehicle through the front fork that moves the front wheel, wherein the front fork passes around the fixed head tube above the front wheel comprises steering the vehicle through the front fork that moves the front wheel, wherein the front fork is connected around the fixed head tube with a plurality of connectors passing through holes in a plurality of curved plates. 16. The method of claim 13, wherein said transferring the power through the moving linkage to the front wheel, wherein the moving linkage is at least partially enclosed within the frame between the crank and the front wheel, wherein the moving linkage is enclosed within the fixed head tube of the frame comprises transferring the power through a plurality of moving linkage in series to the front wheel, wherein at least one of the plurality of moving linkages is at least partially enclosed within the frame between the crank and the front wheel, and wherein at least one of the plurality of moving linkages is enclosed within the fixed head tube of the frame. 17. The method of claim 16, wherein said transferring the power through the plurality of moving linkage in series to the front wheel, wherein at least one of the plurality of moving linkages is at least partially enclosed within the frame between the crank and the front wheel, and wherein at least one of the plurality of moving linkages is enclosed within the fixed head tube of the frame comprises transferring the power through one or more belts and a chain in series to the front wheel, wherein one belt is enclosed within the frame between the crank and the front wheel, and wherein one belt is enclosed within the fixed head tube of the frame. 18. The method of claim 13, wherein said providing power to a crank operably coupled to the front wheel comprises operating a motor operably coupled to the crank, wherein the vehicle is a motorized scooter. 19. A bicycle, comprising: a front wheel and a back wheel;a frame, including a fixed head tube, to which the front wheel and the back wheel are operably coupled;a crank for providing power to the front wheel, wherein the crank is positioned between the front wheel and the back wheel, wherein a plurality of movable linkages convey the power to the front wheel, and wherein one of the plurality of linkages is enclosed within the frame between the crank and the front wheel, wherein one of the plurality of linkages is enclosed within a front fork operable for steering the vehicle by moving the front wheel, wherein the front fork connects the frame and the front wheel, wherein the front fork passes around the fixed head tube, wherein the front fork is mounted to the fixed head tube using at least one connector joining a plurality of plates.
