ABSTRACT:
A speed-variating device especially for a bike includes a first disk secured to a chain wheel having an integral gear formed on a cylindrical flange thereof, a second disk having at least a planet pinion pivotally formed annularly on the second disk engageable with the internal gear, a central eccentric wheel carrying either disk eccentrically about an axle of a bike wheel, a sun gear rotatably mounted on the axle engageable with the planet pinion and having a ratchet gear forwardly driving the bike wheel for forwardly running of the bike, so that a homogeneous wide speed variation can be effected by a first speed variation from the first disk to the eccentric wheel and a second speed variation from the eccentric wheel to the second disk and by a further speed variation by a planetary gear train comprised of the internal gear, the planet pinion and the sun gear for a wider speed variation.
