c. Adjusting coaster brake

Diagram Description: Illustration showing the coaster brake mechanism. Braking is achieved by rotating the pedals backward; more pressure results in more braking force.

Rotate the pedals backwards to brake. The more pressure you apply, the more braking force.

Appendix 2: Recommended Tightening Torque

Always tighten fasteners to the correct torque. Bolts that are too loose can move and fatigue. Bolts that are too tight can stretch and deform.
