ABSTRACT:
A sprocket-actuated bike brake includes a brake shoe swingable against the rear tire by an actuator engaged by the sprocket teeth when the pedal sprocket is rotated in reverse. Using a small number of parts, the brake couples a maximum amount of force from the sprocket to the brake shoe and imparts a drag on the tire which is proportional to the force on the pedals so that the bike has a stop length versus pedal force characteristic which is substantially linear.
