  • Page 14: Using Gears

    Using Gears Some model bicycles are equipped with gears. Gears are used to change the ratio between rotations of the rear wheel and the crank set. This enables you to pedal less and travel faster on flat or downhill sections, or pedal faster and travel slower to climb hills. Gearing is independent to pedal assistance, so pedal assistance operates the same regardless of selected gear.

  • Page 15: Using Brakes

    Using Brakes All bicycle models are equipped with a front and rear wheel braking system. Brakes are used to slow the bicycle down. The braking systems may use different mechanics; however,the functionality is the same, and that is to change the energy of the moving bicycle into heat energy（“friction”): For disc brakes, this means pads made from a special friction material pinching against a disc mounted to the centre of the bicycle wheel.
