ABSTRACT:
A vehicle called a snow cycle vehicle due to its structural as well as operational resemblance with a motor cycle. This snow cycle distinctively includes a body of the bicycle or motor cycle type, a compact endless track and drive unit with the latter being longitudinally and resiliently pivotable and carrying the rear portion of the body, a steering having a steering reduction ratio between the handle bar and a front ski, and adjustable connection between the body and the endless track and drive unit, and a manually-adjustable suspension between the body and the endless track unit. This snow cycle vehicle also includes spring-biased suspension arms and a manually-adjustable spring resiliently supporting the rear portion of the body and the steering reduction ratio is produced by pivoting the ski through a crank arm about an axis parallel to the pivot axis of the handle bar.
