An auxiliary wheel device for a bike capable of providing the stable ride comfort by effectively absorbing shock and improving the driving stability is disclosed. The auxiliary wheel device for a bike includes an auxiliary wheel unit which is connected to a body of the bike to be rotated; a buffering unit for buffering the shock transmitted to the body of the body of the bike through the auxiliary wheel unit; and a stopper which makes the rotation of the auxiliary wheel unit around the body of the bike temporarily stop. When the shock larger than the shock which the buffering unit endures is applied to the auxiliary wheel unit, the control by the stopper unit is released so that the auxiliary wheel unit rotates around the body of the bike. |
