Bicycle trainer with variable resistance to pedaling
First Claim
1. A bicycle trainer for removably attaching a bicycle and providing variable resistance to pedaling, comprising:
- a lifting mechanism adapted to engage a front tire of the bicycle, wherein the lifting mechanism comprises a height controller;
a frame adapted to engage a rear tire of the bicycle, said frame comprising a rear tire support lifting the rear tire and allowing the bicycle to translate backward and forward as the lifting mechanism raises and lowers the front tire;
a resistance cylinder attached to said frame and providing a source of resistance to said rear tire; and
wherein the translation of the bicycle creates the variable resistance as a function of the rear tire pressure against the resistance cylinder as determined by the height of the lifting mechanism.

Abstract
The invention is a bicycle trainer to which a standard bicycle temporarily attaches for exercise and simulated rides. A lifting mechanism raises and lowers the front tire, and in preferred embodiments, a frame engages the rear tire to hold the rear tire in an elevated position against a resistance cylinder. The resistance cylinder provides a force against rear tire revolution and varies the resistance to pedaling. The resistance cylinder can vary resistance against back tire revolution by pumping a resistance fluid into and out of the cylinder, by changing the position of the resistance cylinder in relation to the back tire, or by translation of the bicycle back and forth. In other embodiments, the trainer is electronically controlled to simulate real-world geographical courses programmed into a readable format for electronically maneuvering front tire and back tire positions as necessary to provide resistance to pedaling.
