ABSTRACT:
A speed-variating means for bicycle or the like includes a sliding roller carrier means sandwiched between two driving disks of which one driving disk is rotatably coupled with a hub of a bike wheel and the other driving disk is secured with a chain wheel, each driving disk being provided with radial slots engageable with a plurality of sliding rollers of the roller carrier means, whereby a driving of a bike chain, a first speed variating ratio can be effected between the chain-wheel-secured driving disk and the sandwiched roller carrier means and a second speed variating ratio can be effected between the hub-coupled driving disk and the sandwiched roller carrier means, thereby obtaining a synergetic speed-variating effect by multiplying the first and the second speed variating ratio by means of such a compact mechanism of the sandwiched roller carrier means.
