The present invention is generally directed towards systems for securely retaining an electric motor in a cycle fork, including: a surface feature and a slot, a motor with an axle positioned in the dropout, and a substantially flat insert disposed at least in part in the surface feature and including an opening into which the axle is at least in part positioned. Some embodiments may include a hub motor having an axle with a diameter of 12-14 mm with a non-round cross section with two flats on opposite sides, the axle being threaded; an aluminum fork including a dropout with a slot keyed to accept the axle, and a depression; a substantially flat metal plate 2-4 mm thick, positioned at least in part in the depression, and including an opening keyed to accept the axle; and a nut, threaded onto the axle.
