Abrégé
(EN) The invention relates to a transmission unit with a planetary gearing system, optionally for bicycles or for trailer bicycles. The transmission unit, which is developed for driving small rear wheels, contains a planetary gearing system with a ring gear (7) which is connected to the bicycle frame (9), a planet carrier (3b) with planet gears (6a, 6b), and one or two sun gears (10, 11). The transmission unit further contains a rear wheel shaft (12) which is coaxial with respect to the sun gears or a rear wheel shaft which has the aforementioned sun gear, and the transmission unit contains a driving mechanism (3) which is coupled to the planet carrier or a driving mechanism (3) which is designed as a planet carrier (3b). The invention is characterized in that a bearing (35) internally bears the rear wheel shaft (12) with respect to the bicycle frame (9) from a radial perspective and between the seat of the rear wheel (40) and the planetary gearing system from an axial perspective, wherein the planetary gearing system and an upstream gear unit, for example a chain drive (1, 2), lie on the same side of the bicycle frame. Thus, upstream belt drives, short distances between the rear wheel and the bottom bracket, and single-arm suspensions in the bicycle frame can be implemented. The transmission unit provides one or two gear ratios.
