I read somwhere online that Phoenix and Tucson rank as two of the top cities in the U.S. for bicycling because we have so many bike lanes. I would say 70-80% of my riding is in a bike lane. They are everywhere here.
If you need to go somewhere here in Tucson, no need to worry, there will be a bike lane to take you right where you are going.

I found a map online that has all the bike lanes here in Tucson. There is over 600 miles of bike lanes and bike paths here.
