Definitions

  • the present invention relates to a unicycle having a double acceleration function, which includes two pairs of sprockets connected by two endless chains that can perform double acceleration of the unicycle, a one-way clutch that can continuously move the unicycle foreward even if the operation of pedals is terminated, a height adjustment member adjusting the height of a saddle, a brake member controlling the speed of the unicycle, and a folding member folding the saddle.
  • the bicycle includes a frame, front and rear wheels rotatably fixed to the frame, a sprocket rotated by pedals, an endless chain connecting the rear wheel and the sprocket, and a handlebar attached to a fork.
