A dream bike that speeds away without fuel
- Hazaribagh engineer’s hydraulically powered ‘mutated bicycle’ clocks 82kmph smooth ride

If you don’t mind planting your feet firmly on the pedal, here comes a bike that satisfies your need for speed, boasts a look inspired by American cruisers, runs on zero fuel and doesn’t puff out any smoke.

Santosh Kumar Gupta, a techie from Hazaribagh, has designed and patented what he calls the “mutated bicycle” — an advanced version of the humble two-wheeler aimed for youngsters and professionals who love a swift ride without adding to pollution.

The new generation green “bike” is different, as there is no need to pour fuel or charge any battery, said the inventor, who works for a Bangalore-based photocopy company.

“The chain of the conventional bicycle has been replaced with a hydraulic coil. This bicycle has three gears, which allow the rider to touch high speeds without pedalling much,” Santosh told The Telegraph on Thursday.

The bicycle, which lacks a chain, transfers manual power to the rear axle of the wheel by means of the hydraulic drive or cylinder. The design of the mutated bicycle — named so “because it was technically and structurally altered” — is a quaint throwback to the cruiser bikes made popular by the likes of Harley Davidson.

Santosh added that one could even coast uphill with minimal effort on his bicycle. “Besides being environmental-friendly and low-maintenance, it can work up a speed of 82km per hour if one pedals at the rate of 40 revolutions per minute, thanks to its hydraulic coil and air pressure mechanism,” he promised.

The hydraulic system takes care of shaky terrain with few jerks, said the 25-year-old, adding that the bicycle would also reduce strain on knees.

“It makes low noise even on bad roads and has height-adjustable seat to suit all age groups,” pointed out Santosh, who spent Rs 35,000 on developing his model.

It was his dream since his days as a student of DAV Public School, Hazaribagh, to develop “a bike without engine and zero fuel consumption”.

After pursuing intermediate in 2006, Santosh joined JSS Academy of Technical Education, Bangalore, as mechanical engineering student.

On December 23, 2010, he decided to work on his dream bicycle project.

“After four months of research and hard work. I made my first model and named it mutated bicycle.” He was dissatisfied with two successive attempts, with the models drawing criticism from his peers.

In July 2011 as he graduated, Santosh decided against taking up a job so that he could fulfil his dream project. “I redesigned the bike this April and finally my invention was ready in the first week of October,” Santosh said.

He also obtained a patent for his innovation in April this year.

Now, he is eager to talk to interested companies to start mass production of the cycle and bring its cost down to Rs 30,000.

Santosh admitted that though he joined a photocopy company as mechanical engineer only recently, his father Sheo Prasad, chief insurance advisor with LIC, and mother Meena Devi, a homemaker, backed him throughout.
