My wife and I rented a couple of mountain bikes for 3 days (Giant Trance). While they were a little more expensive than some other places we looked at, the staff more than made up for it. Extremely friendly and helpful. They had the bike suspension already adjusted to our weights and provided maps and route suggestions for our stay in Scottsdale. We've rented bikes from other shops in the Phoenix area and AOA is so much better. Would highly recommend them!
