The world’s lightest bicycle with a 10-speed gearbox has gone on sale in the Japanese city of Nagano. The Maruyama Company has designed the two-wheel vehicle weighing 5.8 kilograms. The new bicycle has been named Takumi or “smart”. Its small weight is achieved by using high-strength carbon.
The diameter of the wheels is slightly over 50 centimetres. The vehicle is convenient in operation. The bicycle is incredibly small and one can take it on public transport that have a no-bicycle policy. It utilises automotive grade, engineering polymers for its structural components, saddle and handlebars and has a level of stiffness, fatigue and impact resistance comparable with aero-grade aluminum.
It has a highly efficient, two-stage chain transmission that incorporates a high quality freewheel and is totally enclosed to protect clothing from grease. It also has very small pneumatic tyres, which is based on recent valve developments, offer an extremely comfortable ride. The only disadvantage is its price. So far, the Takumi is much more expensive than standard models. The carbon novelty is being sold at around $5,000 (around Rs 2.5 lakh) in retail at the local Nagano market. By comparison, a medium-class two-wheel bicycle costs $200-300 in Japan.
