ABSTRACT:
A frame structure for exercise bikes consisting of a plurality of generally tubes for constituting a main frame or seat post of the exercise bike. Each elliptical tube includes two planar walls arranged in a parallel manner with their lateral sides joined by two curved walls to form an elliptical, tubular structure with curved sides. The elliptical frame structure has good structural strength and smooth surfaces to ensure safety. It also simplifies and facilitates assembly, and enlarges contact surfaces between tubes thereby reinforcing the connections.
