Bicycle Trainer with Variable Resistance to Pedaling
First Claim
1. A bicycle trainer for providing variable resistance to pedaling, comprising:
- a lifting mechanism adapted to engage a front tire of a bicycle, wherein said lifting mechanism comprises a height controller for raising and lowering the front tire;
a frame lifting a rear tire of the bicycle;
a resistance cylinder attached to said frame for engaging the rear tire of a bicycle, said resistance cylinder being at least partially filled with resistance fluid for providing variable resistance to rear tire movement, wherein said resistance cylinder comprises a means for moving resistance fluid into and out of said resistance cylinder.

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.
