- the invention further relates to a bicycle or pedelec with the bottom bracket gear.
- the transmission includes at least two planetary gear sets, of which at least one planetary gear set is necessarily designed as a space-intensive plus planetary gear set. Furthermore, at least four switching elements are required. In a further embodiment variant of the transmission, four additional gears are achieved by adding two additional switching elements and an additional planetary gear set. Due to the intended interconnection or connection of the various planetary gear sets, the known transmission has a space-intensive design.
- the present invention is based on the object of realizing a bottom bracket gear of the type described above with as little construction effort as possible and with as few components as possible.
