Abstract
A rider-propelled vehicle comprising a rear wheel assembly, a front wheel assembly, a dual drive and steering assembly, and a drive train. The rear wheel assembly and the front wheel assembly include 24 inch (ISO 507 mm) or larger wheels. Pedals of the dual drive and steering assembly extend laterally exterior from drive links of the dual drive and steering assembly so that feet of the rider straddle the left and right drive link. A steering train of the dual drive and steering assembly is configured so that the front wheel assembly turns entirely forward of the range of motion of left and right handlebar assemblies of the dual drive and steering assembly.
Claims19
A rider-propelled vehicle comprising:
- a frame;
- a rear wheel assembly rotatably connected to the frame;
- a front wheel assembly rotatably connected to the frame and spaced forward from the rear wheel assembly;
- and
- a dual drive and steering assembly that coalesces forces from leg and arm mechanics and accommodates steering inputs without affecting the leg and arm mechanics,
- the rear wheel assembly and the front wheel assembly including wheels having a minimum 24 inch (ISO 507 mm) size.
