so my question was...is one wheel trailer better or two wheel will be much easier? i think two wheel will be more stable+ when u have two wheel trailer u have less pressure on rear wheel of bike....i have problesm..since i am planning to put wheel on the sides...i can not find a one sided hub(dont know how to explain) how to attach wheels ?
