Hi guys, I am looking into getting into cycling. I've never done this before so I am looking at starting out with a price range of under 300$ I understand this is low, just want to get in scratch the surface and see how this goes... I was wondering what size bike I should get I am 5'11 260lbs, I've been looking at a 54cm or 58cm Vilano Aluminum Road Bike 21 Speed...please if you have any suggestions on size Or type of bike that may be my better option... Thanks in advance...
