Gliding over a frozen lake or twisting through a groomed trail—winter riding is best enjoyed with a quick and capable tire that won’t drag you down and still rail through turns.
Inspired by studless winter vehicle snow tires, Cake Eater was designed to have lower center tread height with deep siping for lower rolling resistance while the side lugs remained tall and edgy for biting into soft corners. Studs pockets were added in the transition areas for optional added cornering confidence in icy conditions.

The All-Around Fat Bike
Wednesday sits in the middle of our Trail category, but don’t let that fool you into thinking that’s its only use. With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat tire trail bike that can truly handle anything you want to attempt.
If you do an equal amount of off-road touring as you do hitting trails, Wednesday’s ability to play both parts equally will suit you well. Or, if you’re looking for a fat bike and don’t need the fattest tires on the market, Wednesday’s 26 x 4.6” tire clearance is just the ticket.
"Any day of the week’s a great day to ride a Wednesday."

From log and root covered ribbons of twisty singletrack to miles of powdery snow or sandy beaches, Ice Cream Truck can handle it all. You could probably even hop over a grizzly if the situation arises. Probably.
While we could certainly throw out terms like “confidence-inspiring” and “traction-laden” to describe Ice Cream Truck, those phrases are mostly bull, so we’re not going to do that. We’re not here to inspire you, and we didn’t laden it with anything. What we did do was design a monolith of a trail bike that doesn’t give two shits about what’s in front of it.
Ice Cream Truck solves the problem of having to choose between a fat bike and a trail bike. It boasts a symmetric 190mm-spaced Chromoly frame, suspension-corrected 150mm-spaced fork, and sporty trail-oriented geometry. Supported by massive 4.8" tires, itis ready to deftly tackle nearly any terrain.

- Modern trail bike standards like stealth dropper post routing, 44mm headtube, and thru-axles
- Clearance for a full 26” x 5” tire on 100mm rims

From Singletrack to Snow—One Bike Rules It All
Full carbon frame with a svelte top tube and stay shaping for long rides and epic adventure comfort. The LES Fat features a tailored carbon lay-up for each size ensuring optimal ride characteristics for all rider profiles.
VERIFIED VERSATILITY
The LES Fat fits all fat and plus wheel sizes, via the patented Swinger II dropout system, without compromises to the bike's geometry. The Swinger II dropout system also allows for ease of switching between a geared and single speed set up.
EASY ON THE KNEES
The LES Fat features a kind-to-your-knees narrow Q-factor design. With a minimum Q-factor of 210mm, this is similar to the Q-factor on bikes designed for the narrower 170mm rear hub spacing.
ENGINEERED FOR THE INDIVIDUAL
Our engineers know a bike's set-up is subjective, so for the LES Fat they made it possible to swap the suspension, wheel size and drivetrain to the rider's preference. Ensuring the perfect set-up for ample saddle time.
