Definitions

  • the present invention relates to a board type bicycle, and more particularly, to a board type bicycle which can be driven using both feet and both legs, thereby improving exercise effect.
  • the board type bicycle includes a foot plate on which one foot can be placed, a front wheel which is installed adjacent to the front end of the foot plate, a rear wheel which is installed adjacent to the rear end of the foot plate, and a handle for enabling the steering of the front wheel.
  • the board type bicycle is driven by kicking the ground using the other foot while placing one foot on the foot plate. The traveling direction of the board type bicycle can be changed by maneuvering the front wheel using the handle.
  • the board type bicycle provides advantages in that it can be easily handled since it has a small size, it can be driven even in a narrow space, and rider can feel adequate speed.
  • the present invention has been made in an effort to solve the problems occurring in the related art, and an object of the present invention is to provide a board type bicycle which is constructed to allow both feet and both legs to be used so that balanced exercise effect can be anticipated on the human body.
  • Another object of the present invention is to provide a board type bicycle which can be quickly braked while traveling on a road, so that the occurrence of an accident can be prevented.
  • a board type bicycle comprising a frame; a front wheel rotatably installed on a front portion of the frame to support the front portion of the frame on the ground, and capable of being steered by a steering shaft; a handle connected to the steering shaft to steer the front wheel; a rear wheel rotatably installed on a rear portion of the frame to support the rear portion of the frame on the ground; and a pedal device for driving the rear wheel using force inputted from both feet of a rider.
  • the pedal device comprises a first pedal pressed by the rider's left foot; a second pedal pressed by the rider's right foot; first power transmission means for transmitting to the rear wheel the force inputted as the rider presses the first pedal; and second power transmission means for transmitting to the rear wheel the force inputted as the rider presses the second pedal.
  • the board type bicycle according to the present invention provides advantages in that, since the board type bicycle is constructed to be driven by both feet, both feet and both legs can be used. Therefore, balanced exercise effect can be anticipated on the human body. [13] Also, because the board type bicycle has a brake device for braking a wheel, it can be quickly braked while traveling on a road, so that the occurrence of an accident can be prevented. [14] Further, due to the fact that the board type bicycle can be driven in a stopped state, it is possible to take exercise even in a narrow indoor space.
