发明名称 Exercycle frame
摘要 An exercycle frame for an exercycle having a rider's seat, pedals and handle bars in a conventional arrangement, with the pedals driving a drag wheel below the handle bars through a conventional, sprocket-chain connection. The framework, formed of tubular members welded together, includes a longitudinal body tube extending from the rear floor point to frame forks at the front which carry the wheel. The seat structure upstands from this body tube and a pedal-bearing-retainer tube is attached to the underside of this body tube. Transversely disposed stabilizer tubes with extending arms at the base of this framework holds it in an upright, stable position.
