A general bicycle includes a rear wheel sprocket formed in a multi-stage by a chain so as to enable the rear wheel to be run forward along the road while rotating when a driver rotates a crank by applying leg power to a crank shaft. In a structure that a general bearing is installed on a wheel shaft and a hub of a bicycle with two wheels, the bearing is arranged at two stages, and a stay bar of the rear wheel is coupled to a bearing housing for protecting the two-stage bearing. Moreover, a fork is coupled to the bearing housing of a front wheel, and the bearing is arranged in two stages on the wheel shaft and the hub. Accordingly, flexible rotation can be provided so that the two-stage bearing provides a driver with improved comfort.

    통상 자전거에 있어서 운전자가 크랭크 축을 발 다리의 힘으로 크랭크를 회전하면 체인에 의해 다단으로 구성되는 후륜 스프로킷을 포함하여 후륜이 회전하면서 전방으로 도로를 따라 달리게 된다. 두 바퀴로 달리는 자전거의 바퀴 축과 허브에 통상 베어링이 축에 축설되는 구조를 상기 베어링을 2단으로 배열하고 상기 2단 베어링을 보호하는 베어링 하우징에 후륜의 스테이 바와 결합하고, 전륜의 베어링 하우징에 핸들의 포크를 결합 바퀴 축과 허브에 베어링을 2단으로 배열하므로 회전의 유연성으로 운전자의 승차감의 만족도를 향상한다.
