Description

The Lenz Sport Fat Behemoth is our plus tire machine made for all types of riding with either 29+ or 27.5+ tires. The evolution of the full suspension plus bike is here, and this bike truly does it all. It has incredible traction for climbing steep technical and loose trails and a plush ride quality for fast descents. The stability of this Lenz Bike will impress any rider on those slow technical trails, and you will feel more in-control than ever before. With the same awesome geometry of our standard behemoth, but with adjusted proportions to fit the bigger tires, you will feel comfortable and aggressive for climbing and descending. The Fat Behemoth is also our most versatile plus bike. It can be built with either 4 inches or 5 inches of rear travel and any fork from 120mm to 150mm, and the super short chainstay is designed for maneuverability and to be specific to 1×11 component groups.
