EVERYTHING ABOUT VIETNAM MOTORBIKE TOURS

Any options for 2 backpacks or if we match almost everything in one, what to do with one other backpack these twenty days - perhaps doable to leave it from the rental motorbike dwelling in Hanoi? And can even 1 backpack suit with two of us over the bike haha? Thanks Again for taking the time to read through, Consider and with any luck , reply :)Reg
