Our family of four (me, husband, two kids in college) have been on a number of bike tours over the years -- it's a nice way to see a city and spend some time together. Everyone loved this tour -- lots of fun to ride through different Tucson neighborhoods and get off the beaten path a bit.
As others have said, Jimmy is a wonderful guide -- personable and knowledgeable about the city, its history, and the sights. I also appreciated his attention to safety. The bicycles are well-maintained, helmets were provided, and he took care to alert us to potential hazards. All this and empanadas, too! During the ride, we stopped at a local bakery and Jimmy treated us all to a yummy snack. In addition, Tucson Bike Tours is a well-run business. I had to change our reservation in advance of our tour and received a prompt email response and refund. We also received clear directions and information prior to our tour -- kudos for these customer-oriented communication practices.
I highly recommend this company and the historic tour -- you won't be disappointed!
