Im currently scavaging craigslist for a bike for me. Im 5'10 and 300lbs. Im trying to get more mobile and wanted to start biking but im running into a problem finding a decent bike in my price range(under $200). Ive found a few and wanted some help on if a bike i found is good for the price. The one i found is a Specalized Hardrock for $70. I know its a decent deal but im worried about being to heavy for it. Btw i did go to my local bike shop and tested a few bikes this size to get a feel for them. Here is a link for the bike

Specialized Hard Rock 21 speed mountian bike

Thanks
