Considering to a buffering efficiency to the pushing force and a velocity when pushing the drivingshaft 72 back, the spring 74 needs to have a moderate coefficient of elasticity. Furthermore, the coefficient of elasticity of the spring 74 is unadjustable to fit the user's need. - The main objective of the present invention is to provide a brake device for an exercise bicycle. The brake device for an exercise bicycle has a main tube, a resilient assembly and a driving assembly mounted axially in the main tube, a end cap mounted on an open end of the main tube, and a button attached to the driving assembly. The resilient assembly has a first resilient element and a second resilient element having a second coefficient of elasticity less than a first coefficient of elasticity of the first resilient element.
- The driving assembly presses against the first resilient element and is able to obviously and quickly adjust a pressure of the resilient element. The second resilient element quickly pushes the resilient assembly back and a resistance force applied to a wheel of the exercise bicycle is released.
