i really need to get back to riding my bike. back about 10 years ago i used to right avidly, enough to tear up a lot of mountain bikes. i am looking to start up again and am wondering if i should go buy a cheap 55 dollar bike at wal-mart or start with a good bike that will last? i am 5'8" 375 lbs and will kill cheap bikes. since my last bike purchase i have learned that spending more money on a great product usually is better than spending little money on a crap product. this is where i have an issue i really cant stabd spending 60 bucks on a bike every few weeks because i killed it. so i am really hoping yall could help me figure out what to do.
