Hi Guy's: I am wanting to try and build an ATV trailer for behind my bike. I am wondering if anybody knows some bikes that the wheel hub is NOT a splined hub. I want hubs that are a hub that takes bearings and a stub axle. I hope I make sense as i am not really the guy building it, just getting the parts for my friend . I look at E-Bay for used parts and see lots of hubs but can't see the pictures that well. My friend says hubs that are "splined" are no good to me. Does anybody know what hubs I can look to buy ? Thanks Everybody who can reply,,,,,Happy Riding this season,,,,Terry E.
