Washington, Jan 14 : Taiwan researchers are developing a bicycle that would tell the riders when to change the gear.

They are designing a computer for pedal cyclists that tells them when to change gear to optimise the power they develop while maintaining comfort.

While riding a bicycle, few people know how to adjust the gears to get the most power out of their pedalling without becoming uncomfortable either through having to pedal too fast in a low gear on level roads or straining when going up hill or to maintain a high speed.

Researchers from National Defense University, Tashi, Taiwan, ROC have developed a computerised system that would tell exactly when to change gear.

They have devised a computer algorithm that gives a cyclist a gearshift strategy to cope with almost any cycling conditions and maintain this optimal state without reducing comfort.

The tests have shown that by simulation of a 12-speed bicycle provides a gear-shifting sequence with minimal power losses and gear shifts.

"By following the sequence, riders can operate the derailleur system more easily," said the researchers.

"Riders will also feel comfortable because all gear-ratios can be used, and gear-shifting actions will be smoother," they added.

The computer will automatically adjust to riding conditions, satisfying the human element. (ANI)
