摘要： Embodiments herein relate to a wheelchair gearshift arrangement (10), which comprises an axle tube (20) and a pair of wheel attachment adaptors (30) inserted into a respective end (21, 22) of the axle tube (20). The wheel attachment adaptors (30) further includes a respective axle sleeve (40) adapted to receive and hold a respective wheel axle (51) of a respective complete wheelchair wheel (50). Each complete wheelchair wheel (50) having a respective wheel axle centric, axially translatable, gear change mechanism (52). One or more gear change actuators (80) are arranged within the axle tube (20) such that they are operative to selectively, upon user manipulation of an associated gear selector (60), axially translate the associated gear change mechanisms (52) of the respective complete wheelchair wheels (50). Such translation will affect a change of gear ratio between a push-rim (55) and wheel-rim (56) of each respective complete wheelchair wheel (50).
