Abstract: The present invention 10 discloses a new and novel tricycle with adjustable linkage 48, 54 for varying the drive power for either foot or hand power. Furthermore, the linkage 44, 52 can also be used to vary the wheelbase. Moving the front wheel 14 toward the rear wheels 22 provides for a tighter turning radius. Moving the front wheel 14 away from the rear wheels 22 provides for greater stability at high speed. In addition, the linkage 48, 54 provides for the selective placement along a horizontal and/or vertical plane relative to the seat 24 allowing persons of varying size to comfortably position the pedal assembly 16. Additionally, the present invention 10 has a cantilevered seat frame 30 with the seat 24 at one distal end and the other end forming a yoke 32 connected to the front wheel steering pivot column 34 whereby left movement of the seat 24 results in a right turn of the front wheel 14 and a right movement of the seat 24 results in a left turn of the front wheel 14.
