ABSTRACT:
A foldable multipurpose bicycle includes a foldable main frame, a foldable handlebar assembly, a removable seat assembly, a pair of foldable pedal assemblies, a front brake assembly, and a foldable rear brake assembly. By using a pair of quick-release lock mechanisms, a pair of wheels can be connected quickly to the main frame to form a bicycle for riding on land. Alternatively, a front wheel and a tripod can be connected to the main frame to form an exercise bicycle. Or, a float assembly and a propeller assembly can be connected to the main frame to form an hydro-bicycle for riding on smooth surfaced water. The float assembly and the propeller assembly can be mounted removably on the rear portion of the main frame. The bicycle can be folded into a relatively small wheel-like unit which is capable of being conveniently pushed on the ground.
