My daughter has a paper route and I would like to build a trailer that would carry her papers with decent stability. She is only ten years old so I was thinking of incorporting some sort of small scooter motor or something as a little bit of assist into the trailer for conquering the inclines. I plan on spending the winter months in the planning/building of it, and hey if it works out well, maybe build one for to pull behind my Evox 140.
BTW, The Evox is a great bike, I have loaded her panniers down quite a bit and attached the daughters bundle buggy (loaded with newspapers) and pulled all that extra weight with hardly a problem! Once daughter is a little bigger, I will be giving her the Evox and getting a Burley.

Any thoughts or links etc to help me come up with a good trailer design would be appreciated...
