A continuously variable reversible transmission including an input shaft (2), a housing (1), an input arm (4), first and second CVT shafts (5.6), a fixed input wheel (35), a ratio selector mechanism, an overall output wheel (36) and an output shaft (24). The input arm (4) is fixed to the input shaft (2) and extends substantially perpendicular to the input shaft. At each end of the input arm, a first (5) and second (6) CVT shaft is rotatably mounted, with the axes of the CVT shafts extending parallel to the input shaft. The fixed input wheel (35) may be aligned with the axis of the input shaft. The first CVT shaft (5) is coupled with the fixed input wheel (35), the second CVT shaft (6) is coupled with the first CVT shaft (5) and the output wheel (36) which is fixed to the output shaft (24) is coupled with the second CVT shaft. The first and second CVT shafts may orbit around the axis of the input shaft, such that changing the ratio of at least one of the couplings produces a variation of the speed of the output shaft from forwards, through zero to reverse.
