This is the skibike that won the 1991 North American Skibike Championships. It is also one of the most sophisticated skibikes ever built. Sleek in style and functional in design, this machine represents the high-water mark of skibike evolution. Built in 1990, this skibike contains all the best features developed over the previous fifteen years.
This skibike used, what has by now become, the standard single-steering column with quick release spring and the spring steel shock absorber for the handlebars. The frame is also made from 3/4 inch square steel tubing for the main compression member and small diameter steel rod for the lower tension member. But it is the overall geometry of this skibike that sets it apart. Long and lean, this is an efficient, carefully crafted and well balanced machine.
To take advantage of this, a handlebar grip was attached to the lower frame member just below the seat which made this skibike easy to lift with one hand. Because of its unique geometry, the center of gravity was just behind the hand grip, which allowed the skibike to tilt up slightly when carried, making it very easy to get on chairlifts.
Another notable aspect of this skibike are the mounts for the front and rear skis. The ski mounts use a shaped piece of hardened spring steel that is bolted to the frame. The flat section of spring steel on the rear ski is set into a shaped sleeve and held down by three vertical bolts attached to the sleeve. The spring steel is cushioned on the top and bottom by two thick rubber pieces the same shape as the mount. This arrangement guarantees that the rear ski always remains aligned with the front ski and is always perpendicular to the frame. This rubber cushioned bracket allows the rear ski to be solid, yet flexible and very responsive.
With this configuration on the rear ski, this skibike holds the contours of the hill remarkably well and carves like a dream.
The front ski uses a similar arrangement except that a small rubber cushioned rectangular flange is slid over the center restraining bolt beneath the flat section of spring steel (not visible) to act as a pivot point. This hinge arrangement allows for a wider range of motion of the front ski. Similar to the way the rear ski is attached, the top of the spring steel is cushioned with a thick piece of rubber and held in place with large washers and wingnuts.
Also, because of the added stress on the front ski, especially in deep powder snow, a double piece of shaped spring steel was used in this forward mounting for added support. In addition, the front ski has been reinforced with aluminum side channels just in front of the attachment point.
All together, these features add up to make this one fast, responsive and highly manouverable skibike. This favorite machine is lightweight and strong and one of the coolest skibikes ever built.
