I have a road master... yes a road master, and not one problem. I have a 7G 4 stoke mounted on it regularly haul about 20-25lbs on the rear rack it has with a crate attached to it. Top speed 30mph 22-18 on bigger hills. Everyone was like "ohhh no you're gonna be sorry it's gonna take a s**t on you... Solid as ever and my terrain is rocky full of pot holes and almost no side walks just gravel and dirt paths. I'd recommend it to anyone. Since I've taken her thru some s**tty terrain I know what quality it is.
Sorry about you're frame bro that's always a pain in the ass, looks like it worked out better in the end tho! Cheers
