The Motivational Speaker of Our Lineup
Be the best pumper, bumper and jumper you can be.
The PBJ is one of the longest-standing models in our lineup, and for good reason. Unique geometry developed by our very own Lars n' Bars creates a bike that mountain bikers will immediately feel at home on. Relaxed geometry that is stable at higher speeds and big jumps, yet fun and nimble enough for the tightest of pump tracks. The PBJ will simply make you a better mountain biker and help you take your pumping, bumping and jumping skills to the next level. The new X-long size PBJ has a longer reach as well as a longer chainstay. This size isn't just for tall riders, it's also great for people looking to have a pumptrack/dirt jump bike that fits similar to their trail bike. For days when you go from the mountain, straight to the neighborhood pump track, you can seamlessly transition from bike to bike without any adjustment time.

The Pure Bred Party Animal
The mixed wheel Patrol has a new haircut but is still down for anything and truly unapologetic when it comes to shredding trail
Being one of the longest-standing bikes in our lineup, it was the obvious choice to mix it up. Updated geometry to accommodate the 29" front / 27.5" rear wheels and revised suspension tune might just make you ride all day, and then all night. Jibbing, jumping, pumping and hooting your way down the trail, the updated Patrol loves to party. From bike parks to your local trails, the Patrol isn't concerned with where you ride but rather how much fun you are having.

Meet your Kid's new best friend
One ride on the Ripcord and your kid's Playstation will become a dust collector
Today's kids are riding anything and everything they can get their hands on. From singletrack rides with their parents to the occasional bike park trip or hitting up a local pump track. Our Ripcord kids bike is designed to do-it-all while delivering maximum smiles. The Ripcord looks like a rad adult bike that was put on the photocopier and reduced by 40%. You get all the features of an adult bike but in a sweet package that kids can shred. Features like super-low standover, air front and rear shocks, hydraulic disc brakes and knobby Maxxis tires for superb braking and cornering control. There is a reason why we have a hard time keeping this bike in stock.

MASTER OF FUN
Laufey is our most clever and versatile bike. Instead of saying that Laufey is tailored for one type of rider, we're going to go ahead and claim this fun-loving machine is perfect for everyone. Laufey is omnipotent: it's a slack, simple trail bike that relishes new terrain. Laufey may be someone's first bike or their latest bike. It's inexpensive and attainable, and it's a niche bike that feels at home in even the most exclusive bike collection. It's for first-timers and expert shredders. Ride it in Lycra, shred it in jeans. Laufey is a jack-of-all-trades and master of fun with 29" wheels and a 140mm fork.
29" Wheels
MAXIMUM CAPABILITY AND SPEED
For long, fast rides over varied terrain with the greatest versatility, 29" is the clear choice for Laufey. Wide 2.6" tires offer a bigger contact patch, which means more grip. More knobs are digging into the ground at any one time, increasing cornering and braking traction?
Trail Geometry
- SLACKER HEAD ANGLE - Great Stability
- LOWER BOTTOM BRACKET - Corners Naturally
- LONGER COCKPIT - Room to Move While Maintaining Balance
- LONGER WHEELBASE - Stability at High Speeds
- STEEP SEAT ANGLE - Proper Pedaling Position
- SHORT SEAT TUBE - For Long Dropper Posts
HYDROFORMED
We manipulate the shapes and wall-thickness of our aluminum tubing to increase strength and resistance to unwanted flex. Many of the tubes are butted to save weight in the middle of the tubes, away from the stress of the joints and the weld zones.
Using aluminum technologies as advanced as our carbon manufacturing ensures our aluminum bikes are never second-best.
RELIABILITY
Laufey is designed to see a lot of action. While keeping the frame light, we aimed for the added durability required for a bike that will be ridden hard. Butted and hydroformed tubing ensure the burliness is where it's needed.

ARE YOU THIS RIDER?
Do your friends ask if you intend to ride the chairlift when you invite them out for a 'few' park laps? Do your top routes frequently involve pushing up and down trails that aren't on any map? Do your favorite rides begin or end with headlamps, an ice chest, and great friends? Does your bike have to do everything well to get you there and back again? If you think you might be this rider, then Occam should be your bike.
- Intended Use: Trail To Light Enduro
LINKAGE UPDATE
Occam uses a new two-part linkage design. Fewer pieces mean fewer interfaces, greater rigidity, and a lower chance of something working loose. Additionally, we have created a space in the axel and filled it with a handy 4 key multi-tool which is held securely in place with magnets. Always have the most-used tools close at hand for quick tweaks.
INTERNAL CABLE ROUTING
Occam has our latest, fully internal cable routing, using silicon plugs at the frame entry and exit points and clever conduits linking the front and rear triangle so your cables are fully protected.
ASYMMETRICAL DESIGN
Instead of using a less-efficient "shock tunnel", the Occam offsets the shock to the left side of the frame, allowing the right-side support to be more central and more efficiently deal with the suspension forces acting on the front triangle. This solution enables us to tune the stiffness of this high-stress area without adding unnecessary weight.
THE ASYMMETRIC/OFFSET DESIGN OFFERS UNIQUE ADVANTAGES BEYOND STIFFNESS AND LOW WEIGHT.
Avoiding an interrupted seat tube gives more space for dropper posts plus improves access to the shock controls. Additionally, the tidy design leaves room for a water bottle with easy left-side access.

What if we took everybody's favorite bike and made it a little slacker and little longer? Hell, what if we made it more progressive and coil compatible? And, that's exactly what we did for the Ripmo V2. Active ingredients include: 29" wheels, berm-defying cornering tendencies, and a love for long rides.
The Ripmo and Ripmo AF share the same steep, 76-degree seat tube angle and a rangy but not stratospheric reach, which places riders centrally over the pedals. It makes for an efficient position that can go the long haul. The slack 64.9 headtube angle and 44mm reduced-off set fork doesn't wander while climbing, and doesn't hold you back descending. It works—all day up, all day down, all day in between.
TRACTION TUNE
Our custom-tuned front and rear suspension feature extra-light high-speed compression and rebound damping to deliver unparalleled traction. This allows the wheels to flutter through terrain like a trophy truck storming through a set of whoops.
COIL COMPATIBLE
The Ripmo V2 is compatible with both coil and air shocks due to a more progressive leverage rate. On the trail, it gives the suspension a supple feel throughout the entirety of the stroke, enhancing traction no matter how deep you dig.
DROPPER POST CLEARANCE
Mo' dropper, mo' better. On small frames, you can run 125 – 150mm, depending on your preference and inseam length. On Medium, Large, and X-Large, a 160mm—or, why not run a 185mm? Our shorter seat-tube lengths and low standovers allow you to choose your size based on your reach preference.
TIRE CLEARANCE
You can run overbuilt, chunky tires; you can run light, big volume fast tires, but whatever you run, know that you're not limited by width.
BUSHINGS
Tired of hitting "purchase" on another set of bearings each season? So were we. That's why we use bushings where they make sense, and bearings where they don't. The IGUS bushings in our lower link are lighter, stiffer, and virtually maintenance-free. We believe so strongly in them, we back them with a free lifetime replacement.
LIGHTWEIGHT PREMIUM CARBON FOR EVERYONE
All our bikes are built from the highest-grade materials and optimized for the best strength, weight, stiffness, and ride performance-no matter how much you spend. The Ripmo weighs a svelte 6.25 lbs with a DPX2 shock, and complete builds start at 28 lbs.
INTERNAL CABLE ROUTING
Bikes that look pretty on the outside should look pretty on the inside. We use carbon fiber tubes molded within each frame. Push the cable in, watch it pop out, a beautiful moment indeed.
REMOVABLE ISCG MOUNT
So, you're too fast for narrow-wide chain retention on its own? Challenge accepted. Our removable ISCG tabs allow shredders to bolt on a chain guide, while the rest of us can shave grams.
PROTECT YOUR INVESTMENT
A polycarbonate downtube protector deflects debris, while molded rubber swing arm protectors keep things quiet and clean. And, our simple-yet-elegant linkage protectors stop mud and rocks thrown by the tire, keeping your beautiful bike beautiful.

See You At The Bottom
Even though Jekyll boasts a unique combo of go-fast tech that's never been seen before, it's not a bike that talks. It's a bike that goes.
Where it thrives
Steep, fast, rowdy mountains
What it's built for
Enduro racing, bike park sessions, high-speed mobbing
Highlights
- Full carbon frame, 165mm travel, Proportional Response Tuned
- Fox Float Factory X2 Shock
- Guidler-Idler pulley/chainguide system
Descend into Greatness
It's a hell of a climber but come on. Jekyll was born for the downs. Every part of it crafted for the sweet embrace of speed, every element designed to help you wring a bit more of velocity's nectar from those steep, chunky, high pucker lines you love.
Best. Suspension. Ever.
4-bar meets high pivot meets idler pulley meets size-specific kinematics. For real. If you're not up for suspension buzzword bingo, just know that it grips, floats, and pedals like nothing else. It's always up for getting down.
The Gravity Cavity
The shock tucks cleanly into the twin spar downtube, keeping the bike's center of gravity as low as possible. Wicked stability, instant line changes and one-of-a-kind looks.
Built for You
Well, not you specifically. But someone just like you. With our Proportional Response design, everything—from the suspension layout to the geometry, even the length of the chainstays—is completely customized by size, for performance built just for you.
Suspension Like No Other
High main pivot gives it a bump-swallowing rearward axle path. The Guidler pulley kills the pedal kickback of high pivot systems. The 4-bar linkage keeps braking smooth, traction high and pedaling crisp.
Guidler
Idler pulley + chainguide = Guidler. Clever, right? Idler eliminates feedback from the high pivot swingarm, keeping your pedal stroke smooth, even when the terrain isn't. The guide, well, it guides.
Suspension Built For You
A rider's center of gravity drives how the suspension performs, yet most bikes use the exact same layout for all sizes. Proportional Response Suspension alters the design by size for truly next-level performance.
Proportional Response Geometry
Long, slack and low—and fully size-specific. As the front of the bike gets longer with each size, the chain stay length increases proportionally, keeping the rider centered between the wheels for true "made for you" handling.
Guardhouse
Downtube protector keeps your frame safe from roost and strikes, while letting water and debris pass through.
The Ai Advantage
Our Ai Offset Drivetrain delivers more tire and mud clearance in the swingarm, and more even spoke angles for a stiffer, stronger rear wheel.
