While visiting Phoenix, I wanted to go for a bike ride. The closest bike shop was Trailhead. Over the phone, I was told one price and then it was $5 more when I got to the shop. $40 seemed like a lot to rent a bike for the afternoon and there was no discount for multiple days. They charged me $5 more dollars to rent a helmet, so to rent the bike for six hours (the minimum was $45.). I think the helmet should be included in the price or maybe charge people $5 that don't want to rent a helmet. The bike was in excellent shape, except the seat kept lowering when I sat on it.
