A bicycle seat comprised of a seat body having a sitting surface and a nose, a base, means for attaching the base to a seat post, and means for attaching the seat body to the base such that the seat body is free to move along the longitudinal axis of the base when a locking mechanism is unlocked. In one embodiment, the unlocking is accomplished by lifting the nose of the seat body away from the base, thus providing the capability of dynamic adjustment of longitudinal or fore-aft seat position while riding. In an alternative embodiment, a bolt protruding from the seat body is retracted to disengage the locking mechanism and allow dynamic adjustment of longitudinal seat position without lifting the nose. A vertical adjustment corresponding to the longitudinal position of the seat is taught to maintain, if desired, the same distance between bike seat and peddles for any longitudinal position of the seat. |
