My bike, a relatively cheap Clash bike that I think I got from Wal-Mart, has lasted me a long time. It’s still in great condition after 5 or so years. Not too many bells and whistles, just a bike with a few gears that you simply adjust to your biking abilities (pretty much all good bikes should have gears). It works great on all terrains, but best on pavement. If my memory serves me correctly, it cost around $130. $300—$400 on a bike is way too much in my opinion, especially if you’re not looking for anything special.
