<p>A cycle that has two fixed frame arms extending down on each side of the head tube axis, and a steering arm rotatably mounted in the head tube extends down between the frame arms and has a laterally off-set lower portion. A mounting member is fixed to the lower end of the steering arm and has a hollow cylindrical wheel support section which carries the inner portion of a bearing or bearings for the front wheel, allowing this wheel to rotate while being steerable by the steering arm. A fixed pedal axle extends freely through the hollow wheel support section and is rotatably supported by lower ends of the frame arms, this axle being connected by drive means to one of the cycle's front or rear wheels. Parts of the mounting member have an enlarged interior space relative to that in the wheel support section to accommodate steering movement of the mounting means relative to the pedal axle.</p> |
