Robert Axle Project’s M12x1.25 adapter for Kid Trailers and Cargo Trailers are designed specifically to fit your Rad Power bike or Mahle/EBIKEMOTION Equipped E-Bikes. It allows attachment of any hitch-mounted trailer. These Hitch Adapters fit any trailer that has two wheels and a single point of attachment to the axle. This includes all the two-wheeled child, pet and cargo trailers such as: Thule, Chariot, Burley, Instep, Carry Freedom, and many more.

This adaptor threads onto any rear axle, with a thread pitch or M12 x 1.25mm. It is the most common rear axle sized found on hub motor e-bikes with slotted axles. Retain your anti turn washers. Thread the adaptor/ receiver on the non-drive side hub motor axle. This hitch mount will replace the OEM M12 axle nut.
