I was looking at the Diamond back overdrive it is a 29er available in 3 grades and 4 sizes.It has some nice components and I think would be a great bike in your price range.I'm born again in cycling and decided to rebuild my old classic to start with but intend to build a new bike as all the options become clear.I'm at 325 and have a modest plan of getting down to 275.Go have some fun riding. A partner is a great asset.
