The bicycle crank is the central part of the transmission system, including two cranks (cranks) and one or more toothed discs (disks). It receives the pedaling force from the rider and transmits that force through the chain to rotate the rear wheel, helping the bike move.
Main function
Converting pedaling force: Converting kinetic energy from pedaling force into rotational force to pull the chain and rear wheel.
Changing speed: The number and size of the discs on the crank combined with the rear cassette will determine the gear ratio, affecting the speed and weight when pedaling.
Optimizing performance: Helping the cyclist choose the right gear for the terrain conditions (climbing hills or traveling on flat roads), thereby optimizing pedaling performance and comfort when moving.
