A multi-speed hub for a bicycle that includes a hub shell, a hub shaft
nonrotatably mounted to the bicycle, a driver, a planetary gearing system
for providing a plurality of gear ratios and a control device for
selecting the desired gear ratio. The planetary gearing system includes
first, second and third planetary gear mechanism. The first planetary
gear mechanism includes a first sun gear, a first planet carrier and a
first ring gear, The first ring gear also functions as the planet carrier
for the second planetary gear mechanism. A second sun gear of the second
planetary gear mechanism is connected to the first planet carrier. The
second planetary mechanism includes a second ring gear that substantially
surrounds the planetary gearing system. A pawl carrier including a
plurality of pawls that connect the driver to the planetary gearing
system to provide different gear ratios. A stepped planet gear functions
as the second and third planet gears. The stepped planet gear alternately
engages the second and third sun gears via control pawls.
