<p>An internally mounted bicycle transmission includes a hub axle (3), a drive member (10) rotatably mounted around the hub axle, a hub body (2) rotatably mounted around the hub axle (3), and a gear mechanism coupled between the drive member (10) and the hub body (2) for communicating rotational force from the drive member to the hub body through multiple transmission paths. The gear mechanism includes a sun gear (31) rotatably supported around the axle (3), a planet gear (21) supported by a planet gear carrier (26) for rotation around the hub axle (3) and for engaging the sun gear (31), and a ring gear (29) engaging the planet gear (21). According to the invention, the ring gear is integrally formed with the drive member.</p> |
