Bicycle (Road Bike)
The efficient two-wheeled human-powered vehicle/Transportation
A standard road bicycle is one of the most energy-efficient vehicles ever devised, converting human pedaling into forward motion at roughly 99% mechanical efficiency. A typical modern road bike measures about 1.7 m long, has a seat height of approximately 0.75-0.90 m, and weighs 7-10 kg for a high-end carbon frame model. The standard wheel diameter is 700c (approximately 0.622 m rim diameter). More people worldwide use bicycles for daily transportation than any other vehicle.
