ABSTRACT:
A brake assembly for braking a wheel of a bicycle includes left and right brake arms and left and right brake shoes. Each brake shoe includes a holder mounted to the respective brake arm, a pad unit mounted on the holder and having a friction surface that is brought to frictionally engage a rim side of a wheel rim of the wheel, and a magnetically attracting unit mounted on the holder for establishing a magnetic field such that, in the course of a braking action, the strength of the established magnetic field is gradually increased to be of a magnitude sufficient to generate a dragging force to decelerate the running speed of the wheel rim until the friction surface frictionally engages the rim side.
