I absolutely agree that the best mtbike hauler is motorcycle. I carry 2 bikes and ride 2 up (gf rides with me). When everyone else’s ride is over and they squeeze back into their leg cramping cage for the trip home, our ride continues on. We ride to the riding spot, ride, then ride home. No disassembly of the bcycles and we often take the scenic route back to civilation.
