ABSTRACT:
A bicycle has a front frame portion including a front wheel and handlebars and a rear frame portion including a crank housing, a pedal crank, a rear wheel, and a seat with a flexible fiberglass spring plate removably mounted between upper portions of the front and rear frame portion and a steel cable extending from the crank housing of the rear frame portion to the upper portion of the front frame portion. During operation of the bicycle, the front frame portion can flex with respect to the rear frame portion by flexing the fiberglass spring plate and tensioning the cable against the bias of compression springs holding the cable in tensioned condition. The fiberglass spring plate can be removed and replaced with another plate having different flexibility characteristics for accommodating rider of varying weights.
