Mountain Bike Action Bike Test: KHS 4 Season 3000 Fat Bike
had a quick-release with an adjustable rear dropout, the new 4 Season has a 12×197mm thru-axle. The model we are testing also features an inverted suspension fork by Wren. This year, KHS is also offering a lower-priced version with a rigid carbon fork priced at $1799 instead of the $2499 option we tested.
Instantly, the Maxxis 26×4.8-inch tires and heavy metal-flake paint catch the eye. You’re sure to get a lot of looks wherever you with these monster tires.

On the last 4 Season 3000 we tested, the brakes were mechanical. For improved stopping power on the new 2020 version, KHS outfitted the 4 Season with a dual-piston Shimano MT501 brake set.
The 4 Season tested has a tunable Wren fork with 110mm of travel. Back in our August issue, we did a full breakdown and review of the Wren suspension. Essentially, the key reason to run an inverted fork is that the stanchions that slide up and down are lighter and can respond to bumps faster. Along with that, the design is stiff—front to back—on a strong chassis, while the inverted fork seals point downward to help prevent trail grime from getting pulled into your fork. On top of the fork providing some cushion, the bit of extra squish from the tires proved helpful on some of the rougher sections.
