ABSTRACT:
A foldable bicycle including a frame having a seat structure and a handlebar structure thereon. A front wheel is rotatably mounted on the frame structure through a front column, and a rear wheel is mounted on the frame structure and is powered through a pedal structure including a sprocket connected to the rear wheel by a chain drive. The main frame is foldable about a hinge point in the area of the sprocket through a unique hinge release and locking mechanism. Moreover, the front wheel is rotatable through the front column in a 180.degree. arc so that the front and back wheels become axially aligned when the hinge locking mechanism is released so that a front portion of the frame section can swing about in a 180.degree. arc to become somewhat parallel to a rear portion thereof. In addition, the present invention provides a unique seat structure which can be collapsed and raised to a desired level. Moreover, the fenders can be constructed with relatively light weight and can be easily attached to and removed from the bicycle by a snap fitting action.
