And the nightmare continues in Tempe this time. A simple tune up and flat tire tube replacement. I get the bike back with a new air valve that requires me to purchase a special valve to fill it with air. I get home and the seat is raised so high I can't ride it. Then after adjusting the seat back, I try to ride the bike and only the front brakes are working!!! Back tire brake is snuggly against the tire!!! Good thing I didn't ride it fast or I would have injured myself. Manager Josh says he'll have "Melissa" fix it. Last time she "fixed" my bike, the tire came off when I was riding it!!!! So no, I don't want Melissa "fixing" my bike! Here's a suggestion - try hiring people over the age of 16! Especially when I can get seriously injured by their lack of skills and knowledge! If I had to do it over again I would NOT buy a bike from Dick's Sporting Goods!
