Abstract
The modified gear configuration of the bicycle drive system ultimately allows the rider to operate the bicycle in a very efficient manner. The gears allow for increased torque and power distribution to the bike's rear wheel. In turn, this reduces the amount of effort required to power the bicycle. This allows the rider to conserve energy, particularly when traveling long distances, which makes it easier for the rider to reach faster speeds and climb hills more easily. The bicycle also features taller wheel rims and tires which allow the rider to cover more distance with each pedal rotation in addition to providing a smoother ride.

Referring to the invention in FIG. 1, the Bicycle Drive System frame is constructed from industry standard light weight steel tubing. The frame is similar in design to a mountain bike frame and measures 80⅝ inches overall 15, the seat height 12 is 36½ inches. The frame features a head tube complete with a front fork and handle bars, as well as a top cross tube 4, down tube 5, and seat tube 6 in its center. The bike also includes a rear wheel structural support 7. In further detail, still referring to the invention in FIG. 1 the bicycle includes features typically found on a mountain bike, such as an adjustable seat post, as well as handgrips on its handle bars and the appropriate types of front and rear brakes.
The Bicycle Drive System features a pedal and crankset assembly 9, 10 in its lower central portion. This crankset consists of a single, 28-tooth torque-multiplying primary chain ring sprocket 1. The 28-tooth chain ring sprocket engages an additional geared sprocket assembly 2, which is secured to a crankset incorporated into the frame 13. The modified section of the frame features a lengthened design and includes an angled 7½ inch angled support 8, connecting the frames seat tube 6 to the second crankset housing.
The configuration of sprockets and cranksets allow the operator to impart 1.7 times the torque to the rear wheel with substantially reduced pedal effort. This, combined with larger wheel rims and tires allows for a more efficient use of energy, and enables the rider to reach faster speeds FIG. 3, and travel farther distances with less effort.
