Abstract
The present invention is a bicycle having a frame capable of flexing under downward force so that when downward force is applied a front spring assembly and a rear spring assembly are able to store and release the energy allowing the bike to jump in the air. The spring assemblies of the present invention use bow springs made from fiberglass/epoxy, graphite/epoxy, or fiberglass/nylon instead of traditional coil springs. The bow springs allow the spring assemblies to return a greater amount of energy than their coil spring counterparts while keeping overall weight of the spring assembly down.
Claims13
A bicycle comprising:
- a two piece frame defined by a front end having a front wheel assembly constructed and arrange to permit vertical movement of said front wheel in relation to front end, said wheel assembly including a front axle to permit front wheel rotation, a rear end having a pivot attached to said front end and a rotatable rear wheel mounted thereto;
- at least one bow spring having a first end pivotally attached to said front end and a second end pivotally attached to said front end wheel assembly, said bow spring bendable to store potential energy when a downward force is applied to said frame;
- and
- at least one rear spring located a distance from said pivot, said rear spring having a first end secured to said front end and a second end secured to said rear end, said rear spring compressible for purposes of storing potential energy when a downward force is applied to said frame;
- wherein a downward force on said front and rear end of said frame induces said spring assemblies to store potential energy whereby removal of the downward force results in a release of said energy propelling said frame to jump into the air.

A bicycle fork comprising:
- a steering tube with a top end and a bottom end;
- an upper bracket coupled to a bottom end of said steering tube;
- a right tube and a left tube with a top end and a bottom end, said top end of said right and left tubes connected to said upper bracket;
- a U-shaped base arc having a right lower housing and a left lower housing and a top arc connecting them, said bottom side of said right and left tubes slideably connected to said right lower housing and said left lower housing, wherein said right and left tubes can slide within said right and left lower housings;
- a right bracket coupled to said right lower housing, a left bracket coupled to said left lower housing;
- at least one bow spring having an upper end and a lower end, said lower end of said bow spring connected to said lower bracket, said upper end of said bow spring connected to said upper bracket, said bow spring constructed and arranged to store and return energy when compressed.
