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.

KHS offers options, including a suspension fork for added comfort through rough terrain.

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.

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.

Low tire pressures provide traction and confidence over the rough stuff.


Although fat bikes are exceptional for the traction provided in snow and on sandy beaches, we…
