2018 Ibis Mojo HD4



If you struggled in geometry at school, keeping up with the math behind the ever-evolving frame and angle designs of the modern enduro mountain bike can be a bit challenging. That may be one reason the “longer the better” mantra caught on so easily: there were no numbers involved. Luckily the designers at Ibis are good with numbers and are not overly swayed by fads, so they have taken the trouble to find out exactly what are the best parameters for things like reach and head tube angles to make the Mojo HD4 a beast on any descent, but still agile enough for the climbs between stages.

Anyone who thought the HD3 was the best all-round enduro-oriented bike they ever rode might be a little afraid about what the tweaks to the HD4 might change about the bike. But don’t worry, they only enhance what the HD4 can do without hamstringing those things you loved about the earlier version. Handling over the roughest terrain now provides an added level of confidence that you will almost certainly be killing your own DH personal records. A lot of that effect can be put down to the 64.9 degree head angle. Stability will skyrocket and you’ll be able to plow through the roughest sections at full speed. Ibis also increased the reach of each size largely because they noticed most customers were sizing up already, so each frame size has basically gone up a frame size in terms of reach, which combined with the slacker head angle increases the stability. They recommend a 160mm suspension fork, though you’re good to go with a 170mm as well. That’s because the refined carbon frame ended up being stiffer and more able to withstand the big hits.

Sticking with the dw-link, they didn’t want to mess with that too much since everyone loved how well it worked on the HD3. So the kinematics are the same as they were on the HD3, though more progression in the shock leverage curve has been introduced, which can only give you even more big-hit capacity without bottoming out. And the rear travel has inched up to 153mm. Pedaling uphill remains, if not easy-peasy, at least you can feel like your power is being efficiently transferred since the dw-link manages to decouple the pedaling from the rear suspension meaning that small bumps are absorbed, but your inertia is not. In addition to that, they have made the upper link 30% more stiff and the lower link 40% more stiff than the links on the Mojo HD3, which will also help when climbing.

But since this bike is really all about loving your downhill sections, they have increased the dropper post length capacity, so the larger frame sizes can fit a 170mm dropper post while a small can still accommodate a 150mm, and the internal cable routing will make it all look very clean. In fact, the whole frame offers some very versatile internal cable routing options with its clever cable port system, so you can run full or interrupted housing. Ibis also keeps it real with their 68mm threaded bottom bracket with an ISCG-05 capability so you can mount that chainguide it you want to make sure you’re not dropping a chain on the rough descents that you’ll naturally be seeking out with this bike. With the rough terrain in mind, they have also included a polycarbonate guard that bolts on under the down tube to prevent that gorgeous carbon frame from getting too scuffed and chipped up.

Boost compatible, the HD4 can fit tires up to 2.8 inches on the 27.5 wheels, so you will get the best traction and still be able to take advantage of the nippier-sized wheels. No trail will be too gnarly with the Ibis Mojo HD4.
