I commute 30 miles a day total now to my job on my GT Avalanche. It's terribly sluggish since it is heavy and has 2.1 inch tires on it designed for mud and sand, not pavement. I'm looking to purchase a commuter bike that is real fast on the road that way I can commute quickly with out breaking a sweat like I do on the GT. I'm a total noob when it comes to commuter bikes, all I know is I want something fast and comfortable and around 200$ used. Any commuter bikes out there around that price? I figure the bike is the cheapest way to work since peace in the middle east doesn't look plausible in the next 1000 years. Thanks in advance.
