This trailer’s hitch fits most standard drop outs with quick release or bolt on axles. It cannot attach to bikes with thru axles or hooded dropouts. For more information on what type of drop out and axle your have, please click here. The Cycle Haus carries a standard steel hitch. Please note that we are unable to attach trailers to electric bikes with rear hub motors. If you have a rear hub motor, please be prepared to make this attachment. Bike not compatible? Try one of our bike-trailer combos that are guaranteed to work.
