Big Sioux Power Sports is owned by Jim, Lonnie, Joe and Jimmy Entenman—the same guys who work hard to bring you the award-winning J&L Harley-Davidson and Glacial Lakes Harley-Davidson stores in South Dakota.  After nearly four decades of experience, the group saw big opportunities in the power sports industry and decided to extend their expertise in a new direction. The Big Sioux Power Sports showroom was completed in June of 2012 just across the parking lot from J&L Harley-Davidson in Sioux Falls. While Big Sioux Power Sports is not affiliated with the Harley-Davidson stores, customers can expect the same level of fun, excitement, customer service and community involvement they enjoy from the J&L and Glacial Lakes stores.
