I've wanted a bike trailer for a while, nothing fancy just suitable for occasional hauling. A few weeks ago I survived four miles with a microwave bungeed to my rack but it was a fairly silly thing to do so I looked again and found this, which is cheap, foldable and has reasonable reviews on amazon. Child trailers are a lot more prevalent though and I could probably get a second-hand one really cheap with a bit of patience. I know they won't carry 100kg, but I really don't think that would be a problem. Has anyone tried using a child trailer for cargo, and is there any reason not to? (I wouldn't be putting kids in it at any point.)
