With its lean and beefy frame, oversized 26mm seatost, and Mongoose composite pedals, the 1991 Mongoose Menace M-1 is tough enough to handle anything you can throw at it. The Menace's all-new straight rake fork rewards aggressive riders with spot-on handling response. Odyssey 1999 calipers and chrome-plated rims deliver stopping power on the proverbial dime. If you thrill to the excitement of 50-foot skidmarks, the Menace is also available with a tire-balding coaster brake.
