My biking days ended when I discovered cars. Until that time, I was an avid biker. I recently turned 58 and got the biking "bug" after riding my brother in law's old hybrid bike from the 1980's. I am looking to buy a good hybrid and am considering starting with a Diamondback hybrid at our local Dick's Sporting Goods priced at $299. I tried the stores (Target, Walmart, etc.), but could tell, even after a 40 years absence, that the store bikes are not so good. I tried a local bike shop and was amazed at the selection (and the prices). As a newbie, I cannot justify spending $600-800 on a bike. The Diamondback seems to be fairly well made and the bike fits me well. I realize that more money will get me a better bike, but the Diamondback seems to fit my needs right now. Would a Diamondback Hybrid be an OK choice for a 58 year old new biker? If not, what would you suggest for a first bike?

Thanks!
