A bicycle frame 10 for an electric-motor-powered bicycle, the frame 10 being provided with a motor mount 14 comprising two arms 14a,14b defining a mounting space therebetween for reception of an electric motor 11 and each having motor fixing means 16 for fixing the motor 11 at a respective one of a fixing points. The arms 14a,14b are of substantially identical construction and rigidly joined together in mirror image with respect to a plane 15 bisecting the mount 14. The mount 14 may be located at the junction of a seat tube 12 and a downtube 13 of a bicycle frame, with the fixing means orientated generally vertically one above the other. Each arm 14a,14b may be formed from two halves which are each of integral construction and which are rigidly joined together in mirror image with respect to a further plane 21 bisecting the mount 14, the further plane 21 intersecting the junction of the arms perpendicularly to the first-mentioned plane 15. Consequently, the mount 14 can be produced from a number of relatively small components rather than a single larger component, so as to simplify component construction and reduce component size.
