Hi.
I'm wondering how your bike trailer worked out, as we're starting a trailer ourselves also with 20" wheels. We're having a problem with the axle though, any ideas? 3/8" fine threaded bar isn't going to work with the 'bicycle' thread fasteners and bearings. Not sure if we can make a mount bracket for the outside end of the axles, we were thinking of one running the width of the trailer plus wheels.
Thanks
