A drive apparatus 30 for a human powered vehicle (HPV) comprising a housing 20 attachable to the HPV, a motor carried by the housing, a drive-wheel 25 for providing drive from the motor to the HPV, and a drive belt 24. The drive belt 24 has a bias to adopt, when de-tensioned, a curve with a radius larger than that of the drive-wheel 25. The apparatus further comprises a tensioner 76 being operable to apply tension to the belt 24 whereby the belt 24 can couple the motor to the drive-wheel 25. The tensioner 76 is operable to release tension from the belt 24 whereby the belt 24 can follow a path which is free of the drive-wheel 25. The apparatus further comprises a guide 78a, 78b for restraining the belt 24 outboard of the drive-wheel 25 along the path where the belt 24 is free of the drive-wheel 25.
