PROBLEM TO BE SOLVED: To provide an on-snow bicycle which does not spoil ski-feeling on the snow and is excellent in traveling performance. SOLUTION: A sled plate 2 is fitted in place of a front wheel of a bicycle, and a wheel-shaped sled 3 is fitted in place of a rear wheel. The wheel-shaped sled 3 is of the structure where a plurality of sleds of the same shape are arranged in a circumference, and when not in rotation, the wheel-shaped sled plays a role similar to that of a regular sled plate. When in rotation, a V-shaped rear part 6 is bitten in snow, and pushes the snow backward to obtain the propulsion. A gear 7 is fixed to an axle of the wheel-shaped sled 3 to agree the rotational direction of a pedal with the rotational direction of the wheel- shaped sled 3. The propulsion is obtained by stepping on the pedal. After the advancing speed is obtained, the pedal is stopped, and the skiing on the snow can be enjoyed with the wheel-shaped sled 3 forming a regular sled.
