Abstract

An increasing demand for non-polluting mechanized transportation has increased the interest in the use of electrical power for personal transportation. A low cost alternative to an automobile is a bicycle. The rate of improvements in technology is at an exponential level despite that, the electric bicycle is a concept that has been very feasible for years but has not been fully explored yet. The electric bicycle is designed to provide electromagnetic propulsions to a bicycle thereby relieving the user from having to produce the energy required to run the bicycle. The system design is based on mechanically coupled dc motor which is used as the primary power source to drive the bicycle and electrically wiring the motor together with a rechargeable dc battery. In a PMDC brushed motor, the machine can also run as a generator while pedalling. This energy can be used to charge the battery and can be for either run-time energy needs like phone-charging or either motoring. For more efficient and better charging of the battery, solar panel assembly is provided such that the run-time charging duration is reduced. The term hybrid usually implies that more than one energy source is used to power all or part of a vehicle's propulsion. Rechargeable battery with long life is used for charging. DC electric motor is used in this project. The hybrid bicycle is a project that can promote both cleaner technologies as well as reduce the dependence on oil. It runs on clean electric power with rechargable ability, it runs on the power from the pedals of the bicycle and also through the solar energy.
