Charge Your Mobile Phone as You Exercise!

Bhaskar Ajgaonkar, a third-year information technology engineering student of Rajendra Mane College of Engineering and Technology, Ratnagiri, has developed a bicycle that when pedaled produces electricity and charges mobile phones of any brand.

This 19-year old resident of Dombivli, a distant suburb of Mumbai, was inspired by the two-seater cycle ridden by Shashi Kapoor and Amitabh Bachchan in the movie Shaan. He was in Class VII then. It was his father Vijay Ajgaonkar, an electronics engineer, who encouraged him. The bicycle with mobile charging facility took nearly two years and around a thousand rupees to build.

Bhaskar describes his device: "The circuit is so flexible that you can connect a cell phone of any brand for charging. The electricity generated through a dynamo is regulated through the circuit. Therefore your riding speed will not affect the current flow."

An extra chain is attached to the rear wheel, which is connected to a micro-dynamo attached to the cycle carrier. As the cycle is pedaled, the dynamo rotates to generate electricity. The electricity is then passed towards the circuit fixed on the bell attached to the handle. The circuit has an LED that confirms reception of electricity.

A cable coming out from the circuit has a plug, which can be connected to a mobile phone to charge it. A chain is connected to the micro dynamo and cycle’s gear box. As you pedal the cycle forward, the chain rotates the gear box. The invention thus not only saves electricity but also helps the rider stay fit while he charges his mobile phone.

Bhaskar’s skills have brought him three national awards and several state awards. His most recent award is the KDMC mayor’s award. He has more than 25 innovative cycle designs to his credit. He has won a national award for presenting a prototype of this bicycle at a seminar conducted for Alternative Energy Sources at VPM Polytechnic in Thane in 2005. He took his project further by designing the micro-dynamo with the help of industry experts.

When asked why he decided to work on a cycle instead of cars, Bhaskar said, "The Wright brothers had a vision. They wanted to fly. Similarly, I felt there should be some innovation in cycles too."

By December this year, Bhaskar hopes to complete the prototype of a talking cycle, which will have photo sensors fixed on it. "The bicycle will warn cyclists about potholes ahead and will say sorry to the rider if it misses one. In addition, this talking cycle will caution riders against unnecessary jerks and accidents.

Though his father Vijay Ajgaonkar is currently undergoing medication for cancer, it hasn't deterred Bhaskar from pursuing his dream. He has written a book titled Cyclecha Zagat Mi which is due for release in December.

The budding inventor now hopes to to come up with a flying bicycle based on the airplane model created by the Wright Brothers.
