I wish I had a mountain biking photo, and this is not my favorite Bike Friday photo since it's more from behind (and I have my temporary fill-in icky helmet on), but it's the only clear and semi-closeup photo I could find at the moment. Here I am on my Bike Friday Pocket Crusoe (it looks so tiny, but really rides nicely!)
