12mm bolt style thru axle combined with 37mm double row angular contact bearings, and a right side 3mm thick, stainless steel 220mm brake rotor , make this wheel the last one you'll probably ever have to buy for your All terrain motorized bike! It also comes laced into a high quality double wall, alloy rim, with 11g spokes, and is equipped with a hydraulic pitbike style caliper. Brake lever and hose is not included. The All terrain requires a 1900-2000mm long brake hose, for the rear brake. The hub is machined from billet 6061 aluminum, and has a dedicated mounting surface and bolt holes for a CNC engine sprocket. Sprocket mounting bolts and other hardware are included. Just add your own pedal side freewheel and engine sprocket.
NOTE!- like all our rear wheels, it has a12mm axle. Most, if not all, rear drop outs will need to have 2mm filed from the bottom of each side of the drop outs. This is done quite easily with a flat file or if your careful, a Dremel tool.
