Abstract
Abstract 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.

Claim 1
Independent Claim
193 words
A frame for an exercycle of the type having a seat, pedals and a handle bar in an arrangement similar to that found on a bicycle, and with the pedals connecting with a wheel at the front of the unit beneath the handle bars, said frame including in combination therewith: (a) a single longitudinally extended, continuous body tube inclined from the floor level at the rear of the unit upwardly and forwardly to a point above the aforesaid front wheel; (b) a pair of laterally, spaced-apart frame forks connecting with the front end of the body tube to extend downwardly and forwardly therefrom to the floor level; (c) a rear, transverse stabilizer tube at the floor level end of the body tube; (d) a front transverse stabilizer tube at the bottom of the frame forks; (e) a tubular member upstanding from and connected to the top of the continuous body tube to carry a seat thereabove; (f) a transverse pedal-bearing-retainer tube secured to the underside of the continuous body tube; (g) means to support a wheel between the frame forks; and (h) means to support handle bars within and above the frame forks.
