Modern pedal cycle transmission systems comprise a chain and multiple sprockets, wherein the chain is moved between each sprocket by a derailleur. Whilst these systems are readily accessible by the user for maintenance, they are also prone to failure such as chain detachment or the derailleur mechanically failing. A gearbox for a bicycle is presented that addresses at least this problem, the gearbox 2 comprising an input gear 8 configured to receive a drive input and rotate about a first rotation axis in a first plane; an output gear 4 configured to rotate about a second rotation axis in a second plane different to the first plane; a plurality of drive transfer arrangements 26 intermediate the input gear 8 and output gear 4, each of the drive transfer arrangements 26 comprising a first gear 44 engaged with the input gear 8, a second gear 46 engaged with the output gear 4 and a shaft 58 therebetween, each drive transfer arrangement 26 configurable between a locked configuration whereby rotation of one of the first 44 and second 46 gears causes rotation of the other of the first 44 and second 46 gears such that drive between the input gear 8 and output gear 4 is enabled and an unlocked configuration whereby the first 44 and second 46 gears rotate independently of one another thereby disabling drive from the input gear 8 to the output gear 4; and a selection arrangement 71for selecting one of the plurality of drive transfer arrangements 26 and causing reconfiguration of the selected drive transfer arrangement 26 between the unlocked and the locked configuration.
