Design and fabrication of dual chargeable bicycle

Abstract

With the increase in fuel prices, pollution content in atmosphere and due to gradual end of the non renewable sources of energy we have to alter the source of our energy in our vehicles. Considering all these reasons we have to switch over to other sources of energy instead of using conventional sources such as petrol which in future will be going to extinct. One way to alter the energy source is to go for electric vehicles or e bikes. Electric driven vehicles uses battery as a source of energy which provide power to motor which in turn provide  torque to wheels .The old design of electric bicycle was having only a single mode of charging, it was just capable to travel 15 km through battery and was not ergonomically good. The new design uses a low rpm alternator for charging the battery by keeping it in contact with front wheel .A Motor of 0.5hp provides torque to the rear wheel and the gear ratio is kept 5:2 .battery discharging time is approximately 2 hrs and charging time through alternator is 1 hour and the bicycle can attain a maximum speed of 15 km/hr. This work is more beneficial in hilly region and confined areas like college campus and schools, generating zero pollution, zero noise effect and no fuel consumption.
