  • Publication number: 20240076010
    Abstract: An apparatus to convert a motorcycle into a snow bike includes a front ski assembly with a universal fork clamp assembly and a universal axle clamp assembly. The universal fork clamp assembly is configured to: fasten to fork tubes of the motorcycle from a back side of the front ski assembly; is selectively positionable relative to a spindle body; and is configurable to accommodate a range of fork tube diameters and fork tube spacings. The universal axle clamp assembly is mechanically moveable relative to the spindle body, selectively tightenable to accommodate a range of axle diameters, and selectively positionable to accommodate axles that vary by distance from the fork tubes. The universal axle and fork clamp assemblies couple to an upper portion of the spindle body, and a lower portion of the spindle body couples to a spindle of at least one ski.

  • Publication number: 20240076011
    Abstract: An apparatus to convert a motorcycle into a snow bike is disclosed. In one or more examples, the apparatus includes a tunnel and a mount plate coupled to the tunnel. In certain examples, the apparatus also includes a pair of mount legs, where each of the pair of mount legs is positionably coupled to the mount plate at a first end and rotationally coupled at a second end to a frame of the motorcycle, and where each of the pair of mount legs is positionable independent of the other mount leg.

  • Publication number: 20160280331
    Abstract: A snow vehicle suspension is provided for a snow vehicle. The suspension includes a motorcycle frame, and a rear suspension system pivotally coupled with the motorcycle frame, where the rear suspension system supports an endless track. The suspension also includes a suspension strut pivotally coupled at a first end with the motorcycle frame and at a second end pivotally coupled with the rear suspension system, and at least one shock absorber disposed within the endless track.

  • Publication number: 20150259032
    Abstract: A system and device are provided for a snow vehicle ski. The system includes a snow ski with a bottom surface for gliding over snow and ice, where the base extends longitudinally from a tip to a tail. The snow ski also includes a first keel extending along a first lateral edge of the base, a second keel extending along a second lateral edge of the base, and a third keel extending along a longitudinal axis of the base, and where the third keel extends downwardly from the base a distance greater than the first keel. The system includes wear bars coupled to each of the first, second, and third keels. The device includes a wear bar for attachment to a bottom of a snow vehicle ski, where the wear bar comprises a pair of downwardly extending ridges forming a concave region extending along a length of the wear bar.

  • Patent number: 8910738
    Abstract: A snow bike system includes a motorcycle converted for use in the snow with a rear suspension and belt track system. The belt track is relatively very wide and driven by a front wheel sprocket through a jackshaft. Matching shocks and struts in the rear suspension independently equalize the pressure applied to the ground. The rear strut is a sliding extension type that causes the front of the sliders to kick up when fully compressed during acceleration or climbing uphill. Increased weight on the rear track is shifted forward to keep the front ski down. The jackshaft provides both disc braking and moves the motorcycle engine drive power outboard to accommodate the wider belt track. A tubular subframe and tunnel rigidly mounts to the motorcycle's original rear swing arm pivots and shock mounts.
