Why We Like The Mojo 4 SLX Mountain Bike

With a history dating back to 1994, the Mojo name is known and respected in the MTB community. First introduced as a hardtail, the Mojo has spent the last decade as a fun-loving trail bike with a remarkably efficient suspension platform and a penchant for turning the trails into your own personal playground. These qualities ring true for the latest Mojo 4, but the bike is now more capable in virtually any riding scenario thanks to some tasteful updates from Ibis. These include modern trail bike geometry, a refined chassis, and custom-tuned suspension that lets the Mojo track like a big bike without sacrificing its legendary pedaling performance.

Like its predecessor, the Mojo V4 sports 27.5-inch wheels and 130mm of rear travel, keeping its roots firmly in the trail bike category. This means it favors a more calculated approach than its longer-travel sibling the HD5, but you reap the rewards of a bike that goes airborne on command and can be maneuvered through terrain with absolute precision. Geometry-wise the bike is right on the money for a modern trail bike, with the 65.4-degree head tube angle and generous reach figures giving the bike plenty of stability for fast, technical downhills, and the steep 76.6-degree seat tube providing a suitable perch for knocking out the climbs in comfort. The short 425mm chainstays paired with 27.5in wheels are a magical combination for bunny hopping, wheelies, and jibbing and a surefire way to a smile on any rider's face.

Like Ibis' other bikes, the Mojo 4 is masterfully crafted from premium lightweight carbon, and despite the sub-6lb frame weight, the bike is very sturdy and offers the perfect balance of stiffness vs. compliance. The frame lines are unmistakably Mojo, but the new frame has some subtle yet practical differences from its predecessor. First off, all sizes have low standover heights and shortened seat tubes to accommodate long-travel dropper posts. This gives you the freedom to pick your size based on reach figures, and no matter what size you choose you'll be able to run the longest possible dropper that your inseam can handle. The new frame features simplified tube-in-tube internal cable routing, and it uses IGUS bushings in the lower link instead of bushings‚ a design that's now widespread in the Ibis lineup due to improved reliability and lower maintenance burden. All sizes fit a water bottle in the main triangle, and the bike can be fitted with the Ibis Pork Chop frame bag so you can store your tube, tools, and snacks on the bike instead of on your back.

We'd be remiss if we didn't talk a bit about the Mojo's DW-Link suspension platform, but not much needs to be said other than Ibis has used DW-Link for years and it's arguably the most pedal-efficient design on the market. What has changed with the new Mojo is that Ibis implemented a custom suspension tune that they call Traction Tune. Traction Tune uses extra-light damping in the compression and rebound circuits of the rear shock. This allows the suspension to move as freely as possible when you're barreling across high-speed bumps, providing greater traction and a smooth, predictable feel on the trail. Because of DW-Link's anti-squat characteristics, the Mojo 4 doesn't need heavily-damped suspension to pedal efficiently (unlike many other designs), so Traction Tune makes a lot of sense for Ibis bikes.

*Due to unprecedented demand in the global supply chain and the bike industry over the last 18 months, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be minor. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.
