Mongoose bikes offer excellent value to casual or beginning mountain bikers who ride within their limits. Mongooses' Juneau and Argus Sport steel-framed fat tire mountain bikes feature 4-inch knobby tires with 7-speed Shimano gearing for ease-of-use, as well as dual mechanical disc brakes for safety. Skip Hess was responsible for producing the first US-made wheel for BMX racing in 1974.
