Patent ID: 7470220

Claim:
A bicycle-mounted exercise device comprising: an adjustable clamp, an upper flame, a middle frame, a lower frame, a friction wheel, a braking wheel, a brake pad, and a brake application mechanism; said adjustable clamp being configured to fixedly grasp the post of a bicycle seat; said upper frame being connected to said clamp and extending downwardly to terminate at a lower end; said middle frame being pivotably attached to said lower end of said upper frame and extending rearwardly, said lower frame being pivotably attached to a rearward portion of said middle frame and having a pin extending through said middle frame and said lower frame, said lower frame having a rearmost portion with an opening therethrough, said lower frame supporting brake assembly comprising a brake cable and said brake pad; an axle extending through said opening in said lower frame, said axle supporting said friction wheel and said braking wheel, said friction wheel and said braking wheel being rigidly connected and rotatable relative to said lower frame, said friction wheel being positioned adjacent a bicycle tire, said braking wheel comprising a hub and a cylindrical surface, said hub and said cylindrical surface being rigidly attached, said cylindrical surface having an inner surface and an outer surface; said brake cable having a first end connected to a brake activation mechanism and a second end connected to said brake application mechanism, said brake activation mechanism comprising a brake piston and a brake cylinder, said brake piston extending through said brake cylinder and being movable with respect to said brake cylinder, said brake piston terminating at said brake pad and being securely attached thereto, said brake pad being positioned within said inner cylindrical surface of said braking wheel and radially movable in relation to said inner cylindrical surface, said brake pad moving into contact with said inner cylindrical surface and applying a retarding force against the rotational motion of said braking wheel upon said brake cable being tightened; said braking wheel transmitting said retarding force to said friction wheel, said friction wheel transmitting a retarding force to the tire of a bicycle.
