I just started putting together an HT engine, just to get into the hobby. I chose it at first so I'd at least be able to run some errands with the pannier bags on my rear rack and the low startup cost. If everything works out I'll probably want to move to something more reliable. As of now it looks like that means a rack mounted engine, which brings up a potential drawback of not being able to carry much in the way of groceries or other items. How do you all deal with this? I don't want to have to pull a trailer and I'd only want to be able to carry a couple paper grocery bags at most.
