Re: Trying to make informed decisions for my first MB
I'm 6'1" and about 220lbs. My bike is a NEXT/Vertical/Dynacraft frame, and it's all aluminum like that. I have not had any issues with it, with about 500 miles.
My big concern with Walmart bikes is the way they're put together, and a few parts like bearings. I replaced my entire rear wheel with a double-walled rim, replaced all bearings, and made extra sure everything was in working order.
