Horizontal Forces at the wheels for a bicycle (rear wheel)

Description

Though longitudinally stable when stationary, a bike may become longitudinally unstable under sufficient acceleration or deceleration. The horizontal reaction forces at the wheels for a bike can be calculated by the vertical forces at the wheels and the coefficient of friction, , which is an empirical property of the contacting materials.
