There's an awful lot of cool looking trailers here. Here's the one I'm working on. This is the beta prototype of a trailer I'm developing to sell in the Twin Cities area (Mpls and St. Paul MN) I've been testing testing several wheels and this is the one I have on my bike at home. So far it's been working great. I designed it with the urban user in mind - the box is designed to carry 4-bags of groceries and it's made from recycled materials.
