I didn't mean to suggest that the OP was interested in riding fixed. All I was saying was that sometimes you get people acting like riding a single speed bike is hard when what they really mean is that riding a fixed gear bike is hard. But even that isn't really that hard.
When it comes to single speed bikes I don't understand why the single speed bike isn't the default bike for people who want to ride casually and commute. This is one case where the LBS's don't always seem to be serving their customers the best. Why are they willing to sell thousands of BMX bikes for completely inappropriate uses but when someone wants a single speed that is actually comfortable they get freaked out?
