Trek Bicycle Arnold is your destination for the latest products from Trek and Bontrager, service and tune-ups for bikes of any brand, and a great place to find the perfect road, city, mountain, or electric bike to fit your riding style. We're conveniently located in the Water Tower Place shopping plaza, where we're lucky to be near some awesome places to ride, like Grant's Trail, Cliff Cave County Park, and Meramec (Arnold's Grove) Greenway. We're also proud supporters of the local Jefferson County NICA team. Whatever your experience level and however you like to ride, we welcome you to stop by our bike shop, meet the team, and see what we have to offer. We can't wait to ride with you!
