Abstract: A shock absorbing device for a bicycle, which includes a front fork and two cylinders, the front fork including a frame and two columns each of which has a slot defined therein, the frame having two side plates each of which has at least two rollers rotatably disposed thereto and the column movably disposed and guided between the two rollers by extending a bolt through one end of the cylinder, the slot of the column and being engaged to the side plate, the other end of the cylinder fixedly disposed to the column such that when shocks transferred from a wheel of the bicycle the columns moved upwardly and depress the cylinders to absorb the shocks.

Abstract: Vertical and longitudinal shocks imparted to a bicycle seat are absorbed by a compression spring disposed between the seat and the seat strut, with one end of the spring being mounted to a seat retainer that is moveably secured to a pair of slide plates which are in turn slidably engaged with a stationary strut head. A semi round seat secured to the strut head permits the angle of inclination of the bicycle seat to be adjusted. The compression strength of the spring may also be adjusted by urging a cover towards and away from the moveable end of the spring.
