Folding the BYB With a Pack Rack or Luggage Truss CMT

The BYB can fold even if the bike is fitted with a Pack Rack or Luggage Truss CMT. Before folding, first align the rubber strap perpendicular to the bike frame, as seen in the video. Then fold the bike. For the final step, you should find the rubber strap positioned so that you can firmly pull it over the mount for the Pack Rack or the Luggage Truss CMT and attach it to the ball head pin.
