Summary
The Specialized Fatboy is celebrated for its versatility and performance across various conditions, from snow to sand, making it a standout in the fatbike category. Its design emphasizes stability and traction, with features like wide tires and a carbon fork enhancing ride quality. While it excels in challenging terrains, some reviews note its handling could be more nimble in tight spaces.
Excellent performance on snow and sand due to wide tires
Lightweight and efficient design for a fatbike
Stable and comfortable ride with carbon fork
Encourages active outdoor play, especially among kids
Aggressive geometry for responsive handling
Less nimble in quick, tight singletrack due to long chainstays
Requires attention in high-speed corners and steep trails
Some components may need upgrading for optimal performance
The Fatboy has certainly gone through the most drastic evolution, transforming from a Y-shaped BMX rig to a chopper-style beach cruiser to a high-performance fatbike.

Fatbiking is about fun, adventure, determination, accomplishment, and a little bit of insanity. Specialized has rolled all of this up into a nice package that makes me actually want to go out in 12 degree temperatures to ride in the snow. - Mtbr.com
