This summer I've noticed more cyclists on the streets of Detroit. I'm not sure if this reflects an increase in the number of people riding bikes for transportation, or if I am paying better attention. Can anyone back this up? How many people out there use a bicycle as their primary means of transportation?

I've been living in the city for two years without a car and find it to be a surprisingly bike friendly place. Traffic density is pretty low on most roads [[except for about an hour during the post-work evening exodus of suburbanites) and there is plenty of space for bikes. The winter can be a challenge, but it's not too bad when the roads are cleared.

Please share your cycling experiences.
