I know that I am talking about a folding bike, and an electric one at that, but the salient part of this question is about towing a small trailer with a folding bike, so I thought I would put it in the touring section.
I going to either put a small hub motor in the front of my Dahon (economy option) or a 500 watt hub in the rear (power option) In either case I am going exceed the weight capacity of the bike...actually, if I eat one Frito I will exceed the capacity, never mind the motor, controller and battery The motor/controller/battery combo I am thinking of will check in at about 25 pounds. I have been looking at luggage carriers to use to help me carry my dahon through subway and train stations...As I was pondering this problem I realized that if the luggage carrier had larger wheels, I could use it as a trailer to carry the battery, and then put the folding bike on it (folded up) and use it to tote my bike around. Will the objects put on the trailer be considered a part of the weight of the bicycle? Any ideas about this? It sounds like it would kill 2 birds with one stone...or luggage carrier, I should say.
