A bikeboard is provided to gain power easily and to enhance speed by using a gear and a chain which are similar to a conventional bicycle gear and the chain conveniently. A bikeboard includes two front wheels(1), a main body(2), a wire-typed brake(3), a flat board(4), a joint(5), a connecting part(6), a pedal(9), a large gear(13), a crank shaft(12), a small gear(15), a chain(14), a rear wheel, and a spring(16). A front wheel is made of a urethane wheel. The joint converts a direction and obtains propulsive force with a paddling mode. The crank shaft delivers movement of the pedal to the large gear. The chain delivers power to the small gear.
