Gen 5 motor mounting screw OBSOLETE - BDU31YY, BDU38YY

This is the OBSOLETE Gen 5 motor mount screw. It needs the old node insert to work properly. This screw will not work with the newer hard bushings. Two screws are needed per bike. Sold individually.

There are two versions: short and wide. Short is mm long and long is mm.

Every frame uses at least one short screw. Check with your frame manufacturer to see which combination you'll need. If your frame uses an external battery, there's a good chance that you'll use two short screws. If you have a battery that is internal in the downtube, and you have to remove the motor to access it, you'll use one short and one long screw. If you have a tilt-out downtube, it could be either.
