Abstract (en)
[origin: WO2022129026A1] There is provided a gear system (100) for a pedal cycle (150). The gear system (100) comprises an epicyclic gear set (102) having a sun gear (104), one or more planet gears (106) meshed with the sun gear (104), and a ring gear (112) meshed with the one or more planet gears (106). Each of the planet gears (106) is connected to a planet carrier (110). The sun gear (104) has a connecting portion (118) for connecting to a component (122) of the pedal cycle (150). The gear (100) system comprises a control arrangement that is arranged to control a speed of rotation of the ring gear (112), so as to provide a variable gear ratio to the gear (100) system.
