Looking for any information regarding the Schwinn Stingray Fatboy Chopper, it's likely that Schwinn ( Rumored ) only built a total of 50 of these bikes with the front wheels being the same size as the rear wheel both of which are 20-inch X 4-1/4-inches. I believe that I've found the front forks for sale at Chopperdome.NL 164.00-Euros about $235.00 US Dollars, which would allow for any standard / regular 20-inch Schwinn Stingray Chopper to be converted to a 20-inch Schwinn Stingray Fatboy, price is a lil steep though! One brainstorm that I had was to use the narrow regular stingray front forks and just custom bend the fork tubes to fit the 20-inch Fatboy front wheel. The 20-inch X 4-1/4-inch front wheel is I think still available from ChoppersUS.Com Here's the size as posted on Chopperdome.NL for the Fatboy Front Forks: The Schwinn Fat Boy fork: Extreme wide fork to host 4 1/4" tires. 1/1 8" #S9102 length legs: 730 mm length steering tube: 220 mm width axle: 170 mm width legs: 130 mm Here's the Schwinn Stingray OCC Chopper 20-inch size. Here's the Blue Schwinn Stingray XL Chopper adult size behind the black 20-inch Schwinn Stingray Chopper. Here's the Schwinn Stingray Fatboy Chopper with 20-inch front wheel and 20-inch rear wheel. Hence the Fatboy name! If anyone has information regarding this Schwinn Chopper known as a Stingray Fatboy Chopper please post it here, especially any information where the Fatboy Extra Wide Front Forks can be purchased, other than Chopperdome.NL I would appreciate it if you would let me know! Here's a Pic of the extra wide Schwinn Stingray Fatboy Front Forks sold at Chopperdome.NL $235.00 US Dollars...OUCH!!! The Schwinn Fat Boy fork: Extreme wide fork to host 20" X 4 1/4" tires. 1"1/8" #S9102 length legs: 730 mm length steering tube: 220 mm width axle: 170 mm width legs: 130 mm Thanks Crazy Horse, Peace.
