Why We Like The Mojo 4 GX Eagle Factory Mountain Bike
Equipped with 27.5-inch wheels and 130mm of rear travel, Ibis's Mojo 4 is a spritely trail bike for riders that prefer a playful, agile steed rather than a heavy, hard-hitting enduro bike. The Mojo's lightweight carbon frame and the efficient DW-Link suspension system let us pedal all day and rack up miles with ease, but when the trail gets a bit gnarly the Mojo's capable geometry sees us through to the other side. The Mojo is simply a really fun bike and it responds quickly to rider input, allowing us to flick through corners and navigate jumps and drops without skipping a beat.
The Mojo 4 requires a more calculated approach than its longer-travel sibling the Mojo HD5, but you reap the rewards of a bike that goes airborne on command and can be maneuvered 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 big reason for the playfulness and responsiveness we described above.
The Mojo 4 is masterfully crafted from premium lightweight carbon, featuring a sub-6lb frame weight while remaining very sturdy and offering the perfect balance of stiffness vs. compliance. All frame sizes have low standover heights and shortened seat tubes to accommodate long-travel dropper posts, while also helping us get a nice, low body position while descending. The frame features tube-in-tube internal cable routing, and it uses IGUS bushings in the lower suspension link for 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.
*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.
