A kit for converting a conventional bicycle to a self-propelled snow bike. The kit includes a ski, an elongated member for mounting the ski to the front fork of a bicycle and a bias means for urging the ski to maintain a proper orientation as the ski pitches with respect to the elongated member. When the kit is attached to the front fork, the front end of the bicycle is raised so as to place more weight over the rear wheel for improved traction. Elevating the front end also provides greater ground clearance for the bicycle pedals so the bicycle may be pedaled even though the bike may settle into snow covered ground.

1. A kit for converting a conventional bicycle to a snow bicycle, the bicycle including generally upright head and seat tubes connected by a top tube, a front steering fork journaled to the head tube, handlebars for turning the steering fork, and the steering fork having and a pair of wheel dropouts at a lower end for receiving the axle of a bicycle wheel and a pair of bosses for mounting a front wheel brake to the fork, said kit comprising:a) an elongated ski support member having a lower end and an upper end; b) a ski attachable to a journal at said elongated member lower end such that said ski is free to pitch relative to said elongated member lower end: c) said elongated member having mounting means attachable to the front steering fork including a transverse bracket fixed to said elongated member upper end and being attachable to the steering fork at a location above the wheel dropouts and a transverse rod fixed to said elongated member intermediate the ends thereof and being attachable to the wheel dropouts such that said elongated member lower end extends below the wheel dropouts to extend the length of the steering fork; d) said elongated member having a length as measured from the dropouts to said elongated member lower end that is greater in length than the radius of a bicycle wheel normally supported in the wheel dropouts and said kit when mounted to the fork elevating the head tube of the bicycle to a position higher than the position of the head tube when the fork is supported by a bicycle wheel; and e) bias means extending between said elongated member and said ski that is reactive to the pitch of said ski about said journal to Hen the pitch of said ski and urge said ski to a generally horizontal orientation.
