Coaster hub

(1)
It is a special bicycle brake system, also known as a chain brake or reverse brake. Its working principle is to use the chain to drive the brake mechanism when it rotates in the reverse direction to achieve the braking of the bicycle. This design allows the bicycle to move forward when rotating forward, brake when rotating in reverse, and glide when not rotating. The bicycle can be controlled by turning forward and backward, and it can slow down by gently reversing, so it is particularly suitable for use in many bridge slopes and hilly areas. Due to the lack of a flywheel and a pound structure, the bicycle is silent when it stops and glides, which is its unique feature. The coaster hub has the advantages of a wide braking range and good effect, smooth and smooth deceleration, easy disassembly and assembly of the bicycle, quiet gliding, good reliability, etc. At the same time, it does not require warranty wire pipes and operating systems such as brake handles and transmission rods.
