Syncline by Outside Van isn’t just a camper; it’s a high-performance gear locker on wheels. For mountain bikers, the transition from the trailhead to the track should be seamless, and that is exactly where Syncline excels and also why Syncline is the ultimate Mountain Bike Adventure Van.

Built on the Mercedes-Benz Sprinter 144” AWD chassis, this van is engineered to get you to the most remote singletrack while keeping your expensive rigs safe, clean, and ready to ride.

Why Syncline is the Ultimate MTB Basecamp

Most “off-the-shelf” RVs treat bikes as an afterthought, dangling them off a rear hitch. Syncline treats them like the VIPs they are.

• Interior Gear Protection: Syncline features a dedicated garage space with integrated L-Track. This allows you to secure multiple bikes inside the van, protecting them from road salt, rain, and—most importantly—theft.

• The “Mud Room” Philosophy: After a rainy lap, nobody wants mud in their bed. The Syncline’s utility-first flooring and  exterior shower allow you to spray down your bike and your gear before it ever touches the living quarters.

• Modular Storage: With premium overhead cabinetry, dedicated storage bin, MOLLE Panels, and extensive runs of L-Track,  you can organize your helmets, pads, tools, and spare parts without cluttering your living space.

• On-Board Air: Syncline is not just a toy hauler, with a powerful twin on-board air compressor you can keep your tires topped off wherever you set up camp.

• Room for E-Bikes: The garage space and FoldAway Murphy Bed are specifically designed to be able to fit taller E-Bikes and Fat Tire Mountain Bikes. The FoldAway Murphy Bed has recessed spaces under the bed frame so your handle bars will fit snugly underneath while the bed is deployed.

Built to Handle the Weight

Mountain bikers rarely travel light. Between the tools, the extra wheelsets, and the bikes themselves, you are carrying a lot of “sprung weight.” This is why Outside Van integrates professional-grade suspension into Syncline.

The optional Fox Performance Elite Series 2.5 Shocks are a game-changer for this build. They feature Dual Speed Compression (DSC) adjusters, meaning you can stiffen the ride for the highway trek and soften it once you hit the washboard access roads leading to the trailhead.

Off-Grid Power for the Long Haul

Syncline is equipped with a massive lithium power system, allowing you to run your induction cooktop, fridge, and even the A/C without plugging in. For the modern rider, this means you can also keep your e-bike batteries topped off overnight using the internal power outlets, ensuring you never miss a morning session.

To make Syncline the ultimate mountain bike basecamp, you need a highly organized garage. Because Outside Van builds use the L-Track (Logistic Track) system, you can securely bolt, snap, or hang your gear exactly where you need it.

Here is a curated list of essential L-Track accessories to turn your van’s “gear garage” into a professional-grade mobile shop.

Essential L-Track Bike Mounts

The foundation of a Syncline garage is how you secure the bikes. These mounts interface directly with the floor or wall tracks to keep high-value carbon frames from moving during off-road transit.

• RockyMounts DropTop Bolt-On: This is a versatile truck and van mount that handles both thru-axles and quick-releases. Its locking handle provides extra security for those quick post-ride stops at the brewery.

• Freedom Coast Adjustable Fork Mounts: These thoughtfully engineered thru-axle style mounts effortlessly attach to Syncline’s floor L-Track and allow for forward and backward adjustments to get your bikes in the perfect position.

• Sunlite Fork Mount Bike Block: A simple, low-profile solution for securing a bike by the front fork. It’s easily bolted to an L-Track stud fitting, allowing you to stagger multiple bikes to maximize width in the 144″ Sprinter chassis.

Organization & Utility Hardware

Once the bikes are in, you need a place for “the stinky stuff”—helmets, pads, and muddy shoes. These fittings allow you to utilize the various L-Track points found in Syncline.

• Single Stud Fitting with Ring: These are the “Swiss Army Knives” of van organization. Snap them into any track to create an instant anchor point for bungee cords or to hang a damp jersey to dry.

• L-Track Threaded Stud: Use these for more permanent fixtures, like mounting a dedicated tool roll or a small air compressor. They provide a rock-solid threaded post that won’t vibrate loose on washboard roads.

• L-Track Hooks: A handy swiveling hook makes any run of L-Track your personal closet space. Ideal for light items, we like to attach hooks to the L-Track strip above the waterbox so wet clothes can drip dry into the shower pan keeping your van nice and dry.

• L-Track Dedicated Helmet Hook: A durable, modular solution for keeping helmets and gear secure, protected, and off the floor.

Pro-Tip for Syncline Owners:

To prevent “handlebar tangling” when loading three or more bikes, use the L-Track’s modularity to mount your fork blocks at different heights or depths. This “staggered” layout is the secret to fitting a full quiver of bikes into a 144″ wheelbase van without sacrificing living space.
