Excellent bike for larger people!

Very happily surprised when this arrived to my home. Packaged way better than any other bike I've seen shipped. No damage whatsoever. This 29” hard tail is perfect for taller people. I am 6' and 235 lbs and it is perfect. Derailleurs will need tuning but other than that, it's a steal of a deal! The frame shape and composition are very similar to the $500.00 Ozark Trail bikes which I was happily surprised! Will definitely upgrade the pedals but that's the only thing I can say I'd be changing.
