The goal of the project is to convert a standard twenty inch bicycle wheel into a retrofit hydraulic powered wheel. The wheel will harness energy in a self-contained storage unit (the high-pressure accumulator) which will drive a power train including various gears, a motor and a pump.

The bike wheel converts braking energy from deceleration to fluid energy at high pressure. Energy is released through the conversion of mechanical energy when acceleration is desired after the bicycle comes to a stop. The high pressure fluid energy drives a mechanical motor which conve1ts fluid energy to mechanical energy by the use of gears, which tum the wheel. The fluid energy is used to accelerate the bike along with the rider to between ten and fifteen miles per hour.

High pressure (4000 psi) fluid energy is about seventy percent efficient as calculated by the Environmental Protection Agency (EPA), and it is much higher compared to the efficiency of technologically advanced gasoline combustion engines, which is about thirty percent at best.

A battery powered rear drive wheel is incorporated into the bicycle to maintain cruising speed. Lead-acid batteries, speed control, and supporting harness are to be mounted to the bicycle frame.
