The Ibis Mojo HD4 Carbon GX Eagle Complete Mountain Bike reboots the HD3 and creates a super Mojo that recreational riders and Ibis' own enduro race team have been asking for. Ibis tweaked the geometry for bigger hits and higher speeds by extending the reach and wheelbase and slackening the headtube angle. Ensuring that pedaling and climbing performance was not compromised, Ibis steepens the seattube angle. Ibis calls on the gurus at FOX to supply the new Float DPX2 shock with reservoir, and FOX complied with a tune for more ramp-up, preventing harsh bottom outs and ably floating across roots and rocks without missing a beat. The new HD4 is already proven on the EWS circuit by Ibis' professional race team and separates itself from the rest of the lineup as the fastest, burliest, most capable bike on offer from the brand.

On paper, the biggest geometric change between the HD3 and HD4 is reach. Ibis noticed that many riders were sizing up to achieve the reach they desired. Now, the sizing is more modern and you will no longer have to go up a size if you need a roomier cockpit. Shorter stems are also more welcome, making for a more responsive ride in spite of the slacker angles. Stretching the front end leads to an overall longer wheelbase so blasting about the woods is a little less hair-raising and a little more in control. The bike is a lot more smash and a lot less tip-toe.

Relaxing the headtube angle calms the bike down even more when the throttle is open on rough trails. Ibis built several prototypes and put the frames under their athletes and the general consensus netted out a 64.9-degrees. This number might seem DH slack—and indeed this angle isn't far from downhill geometry from just a few years ago—but keep in mind that enduro tracks are practically DH-steep and full of gnar, so we feel A-OK with it. This bike is sure to see plenty of shuttle, park, and lift access, further recommending the choice of such a slack headtube angle.

The DW-Link platform remains Ibis' choice for governing the shock's stroke, and we're continuously in amazement with how well DW bikes pedal. The anti-squat characteristics require very little compression damping and rarely do we find ourselves reaching for the lever to firm things up. The travel is quite linear, is ready and able to smooth out any trail conditions, and feels completely bottomless. Part of this is the excellent kinematics engineered into the frame. The second part is the custom tune on the FOX DPX2 shock, which is proving to be an excellent trail and enduro shock. Modern enduro courses are rougher and longer than ever so the addition of the reservoir is an excellent call since the shock is able to continuously cycle oil allowing it to dissipate heat and run longer and harder without compromising performance. Rear end rigidity has bumped up thanks to an increase of 30 and 40% to the upper and lower links, respectively. The travel also grows slightly, up from 150 to 153mm.

Ibis construction on the Mojo HD4 is first rate, and the beauty of the frame is more than just skin deep. The one-piece carbon layup yields a stiff, very strong, and surprisingly light frame considering the abuse it's expected to take. All sizes have short seat tubes, improving standover clearance and allowing the use of longer dropper posts. Internal routing for cables and housing keep things clean and rattle-free.

The GX Eagle build boasts a massive gear range across its 10-50t cassette. Ibis specs the 738 Very Wide Aluminum Asymmetric wheels, and they have a 34mm internal width. The width is instrumental in getting the most out of the 2.6-inch Maxxis DHF Wide Trail Tires so you can rail the turns and get away with less air pressure in your tires. FOX's Float 36 fork sets the benchmark for smooth, plush, controlled travel in a stiff chassis.
