This would make for an excellent Bug-Out Bike, lightweight and wider tires.
Specialized Fat Boy fat bike. The Fat Boy moniker has been in the Specialized line for more than two decades, gracing BMX race bikes and tires. It’s back for 2014, and is an apt title for the company’s first fat bike.
A size small Fat Boy weighs 14kg 30.8lb with pedalsIt appears that the California-based company has done its homework in creating this beast. The Fat Boy has an aluminum frame with clearance for 4.8in tires and a 100mm-wide PF30 bottom bracket. Front dropout spacing is 135mm, while the rear dropouts are set at 190mm.The tapered carbon fork is loosely based on the Chisel found on several of Specialized’s ridged 29ers, including the Crave 29 SL singlespeed and Stumpjumper Expert Carbon WC.One of the most interesting things about the Fat Boy is its rims, which feature a trusswork design that keeps them stiff and quite light by fat bike standards. They are 90mm wide, have a claimed weight of 795g each, and feature a hookless bead first used on the company’s carbon Roval wheelsets.
