No need to explain that :( My option is 'several trips with backpack', hehe... but most my cases is cycling for fun rather than to the market, I prefer less weight of th bike. See, my home doesnt have an elevator - any time I want to go out with a cycle, I have to carry it on my back for five floors down ... and then, carry it back at the end of the trip. Thus, weight of the bike is of no small importance to me.
