Bicycle Girl

Track bicycles do not have dedicated brakes. Brakes are not required for riding on a track because all riders ride in the same direction around a track which does not necessitate sharp deceleration. Track riders are still able to slow down because all track bicycles are fixed-gear, meaning that there is no freewheel. Without a freewheel, coasting is impossible, so when the rear wheel is moving, the crank is moving. To slow down, the rider applies resistance to the pedals – this acts as a braking system which can be as effective as a friction-based rear wheel brake, but not as effective as a front wheel brake.
• Suspension
Bicycle suspension refers to the system or systems used to suspend the rider and all or part of the bicycle. This serves two purposes:
To keep the wheels in continuous contact with rough surfaces to improve control.
