I always walk my bike backward unless I'm backing down hill and it rolls on its own
I laugh my ass off watching riders paddle walk backward cause their to lazy to back it up before they get on the bike, its the same riders that are too lazy to dismount when they gas up
you shouldn't be "backing up into a spot unless your backing down hill
if your backing even on a slight upgrade yer asking for the bike to roll off it's sidestand, first gear is not a parking brake
