1/6/2023 0 Comments Bicycle average speedIf every athlete has an equal chance of winning the challenge for engineers and scientists then is to focus on the technology the cyclist uses to obtain a competitive advantage. The resistant forces that slow a cyclist are mainly air resistance, total mass and any frictional losses, such as the drivetrain or the rolling resistance of the wheels against the ground. The rider’s ability to produce power is generally down to their physiology and biomechanics. The ability to improve speed on a bicycle comes down to two fundamental factors: you either increase the power that propels the rider forwards or you decrease the resistant forces that are holding that rider back. Though we’ve stuck to the basics, man and his machine have increased in speed from the 14.5 km per hour reportedly achieved by Karl von Drais in 1817 to a mind-blowing 55km in a Tour de France time trial nearly 200 years later. A modern bicycle is still made up of a double diamond shaped frame, two wheels with air-inflated tyres and a chain-based drivetrain – the mechanism through which the whole system runs.
