Abstract

A dicycle includes a pair of parallel wheels, a crankshaft to whose end portions the wheels are attached, upwardly extending control rods connected to and pivotable about the axles, and lever members which extend downwardly and contact the ground at a point which differs from the point of intersection of the vertical to the axles and the ground. When riding the dicycle, a turn can be accomplished easily by pulling a control rod and thereby raising a wheel from the ground.

Claims

1. A dicycle comprising a pair of parallel wheels, a crankshaft having coaxially extending end portions defining wheel axles, said wheels attached to said axles, a means for changing vehicle direction comprising generally upwardly extending control rods connected to and pivotable about said axles, lever members having longitudinal axes, said lever members attached to said control rods, wherein said axes of said lever members intersect the ground at a point which differs from the point of intersection of the vertical through said axle and the ground each of, said lever members being independently pivotable about said axles, whereby steering of the dicycle is effected by pulling one of said control rods, such that a bottom end of the lever member on the side of the pulled control rod touches the ground and the wheel on the side of the pulled control rod is raised from the ground and rotates idly.

2. The dicycle set forth in claim 1, comprising foot pedals mounted on and freely rotatable relative to said crankshaft.

3. The dicycle set forth in claim 1, comprising an upwardly extending leg member attached to the center of said crankshaft, and a saddle mounted on the top of said leg member.

4. The dicycle according to claim 1, wherein said control rod and said lever members include an obtuse angle.

5. The dicycle according to claim 1, wherein said control rod and said lever members are aligned in a straight line.

6. The dicycle according to claim 1, wherein said control rod and said lever members are aligned to form a curved line.

7. The dicycle according to claim 1, comprising castors attached to the bottom ends of said lever members.
