Pedal-powered means of transportation has rotatable saddle support construction consisting of different materials and construction elements to guarantee function and rigidity of overall construction

摘要

The pedal-powered means of transportation in the form of a bicycle has a seat rotatable around the bottom bracket bearing in the vertical longitudinal plane of the frame and guided and retained by other elements of the frame. The saddle support construction (101) with a rotatable mounting on the bottom bracket bearing axis or bearing bush consists of different materials and construction elements which guarantee the function and rigidity of the overall construction, and is formed so that its rotational movement despite other functioning elements of the bicycle is not impaired in the required angular range.
