ABSTRACT:
A bicycle hub transmission basically includes a hub axle, a driver, a hub shell, a power transmission mechanism and a shift mechanism. The driver is rotatably supported relative to the hub axle. The hub shell is rotatably supported relative to the driver. The power transmission mechanism includes a downstream planetary gear unit and an upstream planetary gear unit disposed between the driver and the hub shell to selectively transmit rotational power from the driver to the hub shell through one a plurality of power transmission paths. The shift mechanism is operatively coupled to the power transmission mechanism to select one of the power transmission paths. The downstream planetary gear unit includes at least a planetary gear carrier that meshes with planetary gears of the upstream planetary gear unit.
