Hello, hoping to get more commuting type riding into my life. I have an old kid's pull behind trailer I plan on repurposing for this. It is currently setup to clamp on the chainstay, and has two wheels like every other kids trailer I've seen. I have the tools/abilities to weld whatever type of frame I want and use parts off this trailer. But what's the benefit of the single wheeled trailers compared to a two wheeled trailer? I also plan on making a mount so I can clamp my mountain bike to it and tow it with my roadie to the trails and eliminate having to drive to ride the dirt.. see if that really happens..
Another question, is it much better to attach the trailer to the seat post rather than the chainstay as my trailers currnet configuration is? Is it worth the effort to change it so it does mount to the seat post? I think I'd rather it mount there, but if it's not really a benefit not sure if I will do it.
Thanks for any input
