ABSTRACT:
A two-wheel drive hand and foot powered bicycle in accordance with the present invention includes a rear wheel that is driven by a foot pedal via a chain and derailleur mechanism. A front wheel is rotatably mounted to the bottom portions of first and second yokes. The first yoke is pivotally mounted to the front portion of the bicycle frame and the upper portion of the second yoke is rigidly mounted to the first yoke by a steering coupling member, wherein a steering torque applied to second yoke pivots the first yoke to turn the front wheel. A hand crank assembly is rotatably mounted to the steering coupling member and the upper portion of the second yoke. Power generated by operation of the hand crank assembly is transmitted by a chain to a sprocket assembly mounted to the front wheel. The operator may selectively power the front wheel, the rear wheel, or both wheels simultaneously. The lengths of the second yoke and the steering coupling member may be adjusted to properly position the hand crank assembly for a specific driver by telescopically moving an inner segment into or out of a tubular outer segment. The selected length is fixed by inserting a bolt through complementary apertures in the inner and outer segments and attaching a lock-nut.
