I've ridden mine 197 miles since I bought the bike on March 10th. That's about 14 miles a day. I try to get in 200 to 400 miles a month although I go higher some months and usually during the awful summers here in SC, I go down in mileage. I'm also a slow rider though and I'll admit that any road bike will blow me out of the road speed wise. But I don't ride for fashion or speed, I ride because I enjoy riding and it's good exercise.

As far as keeping a bike for 10 years, I could do that with a Walmart bike easy. Unless the frame totally falls apart or gets wrecked, there isn't a part I can't replace or repair. But I like a new ride each year or when I do tours that take me several days away, it's just easier to donate the bike to charity and take the bus back without the hassle of having to return the bike.

One year, I'll probably go to an LBS to get a recumbent unless Walmart starts selling them. I've always wanted one of those eventually, maybe when I can grow a more white beard.. (Kidding of course, so many bent rider seem to have a salt n pepper beard).

Like I have said before, if you want to ride in organized group rides, want to race, or want to look like Tour De France riders, Walmart bikes are not for you. If you just want to go out and have fun and exercise in a pair of sweats or shorts, Walmart bicycles are great.

PS - I do own a road bike, a 99 dollar bicycle back in 2006. Works great, rides great, and I go about 4 to 6 MPH faster but I don't like the real harsh ride. I use it really if I want a quick ride.
