The Ibis Mojo is a bike with a long history and a loyal fanbase. After the success of the Ripmo, which fills the gap between the Ripley and the Mojo, it was only a matter of time before Ibis would update their classic. That’s just what they’ve done with the Mojo HD 5.

We have to admit, we were quite surprised to see Ibis continuing with smaller 27.5″ wheels on the new Mojo. However, the geometry is on-trend as the Californian brand has made the bike significantly longer and slacker. The reach has grown by 20 mm compared to its predecessor and the head angle has been slackened by 0.7°. The seat tube angle is a whole 2° steeper, which promises a relaxed pedalling position on the climbs. The new Mojo HD5 offers 153 mm travel at the rear and is paired with a 170 mm fork. As with all of Ibis’ full-suspension bikes, the rear end features a virtual pivot point DW linkage , which is controlled by a FOX X2 Factory shock on our test bike. The shock features an extra light compression and rebound damping tune to offer maximum traction, but more on that later. Ibis leave the build for their customers to choose. This allows you to configure the bike to suit your preferences and budget. Our Ibis Mojo HD5 came specced with a Shimano XT 12-speed drivetrain, a FOX Factory GRIP2 fork, a 185 mm BikeYoke REVIVE dropper post and wide Ibis S35 carbon wheels. The 2.5″ MAXXIS ASSEGAI WT EXO+ tires inflate very wide on these wheels, promising to offer a lot of traction and comfort. On closer inspection of the Mojo HD5, you’ll see the attention to detail Ibis are renowned for. The frame protectors and other hardware make a strong impression. The only thing that annoyed us was the rattling brake pads in the Shimano XT four-piston brakes, which we encountered on several of the bikes in the test field.

Geometry and size of the Ibis
Compared to its predecessor, the geometry of the new Ibis Mojo HD5 has been brought up to date in every respect. The reach is longer, the head angle is slacker and the seat tube angle is steeper. We loved the very short saddle and the low slung top tube, both of which allow for maximum freedom of movement on the bike. We were struck by the long head tube and the resultingly high stack, which makes you feel at one with the bike.
|Seat tube||356 mm||368 mm||419 mm||470 mm|
|Top tube||582 mm||606 mm||635 mm||669 mm|
|Head tube||109 mm||126 mm||142 mm||158 mm|

|Stack||595 mm||611 mm||626 mm||640 mm|
The Ibis Mojo HD5 on the trail
As on the Ripmo, the pedalling position on the Mojo HD5 is central, upright and super comfortable. The suspension responds sensitively and offers loads of traction on technical terrain, thanks also in part to the voluminous tires. Monotonous climbs will have you reaching for the climb switch to suppress the slight pedal bob. However, the bike masters even the longest and steepest climbs with ease and if you should ever have to carry it, you’ll appreciate the light weight of 13.84 kg.
The rear end of the Mojo HD5 sticks to the ground and offers an unimaginable amount of traction.
On the descents, we immediately noticed how much traction the suspension of the Mojo HD5 is able to generate. With their so-called “Traction Tune”, Ibis have tuned the rear shock with minimal rebound and compression damping to allow the rear to respond extra sensitively and keep the wheel stuck to the ground. The 153 mm of available travel feels like a lot more and it harmonises perfectly with the 170 mm fork up front. However, there is a downside: the bike absorbs too much of the rider’s input, which makes it less fun to ride on flow-trails. It is evident that the Ibis Mojo was designed primarily with steep, demanding descents in mind. The slack head angle and short chainstays demand a very active riding style to keep the front end sufficiently weighted to generate enough traction. Unless you’re careful, you’ll quickly lose control of the front end, but thanks to the tall stack height, you feel confident on the bike and it invites you to push your limits.
For a bike trimmed towards traction and control, the small 27.5″ wheels don’t make much sense.
How does the Ibis Mojo HD5 fare against the competition?
The Nukeproof Mega 275 Carbon is the only other 27.5″ bike on test. In direct comparison, the rear end of the Ibis is noticeably more sensitive despite having less travel, but it also feels less defined. The Ibis requires a much more active riding style to generate enough grip on both wheels, while the Nukeproof is more forgiving and balanced. When things get rough and demanding, the Mega, with its longer chainstays is more composed, allowing you to conserve energy while going faster.
Tuning tip: none – if this is the kind of bike you’re looking for, it’s perfect
The Ibis Mojo HD5 is a great choice for those who prefer pedalling themselves to the top of the trail-head and tend to ride down particularly steep, tight and technical trails. However, it can’t keep up with the competition on faster trails with its smaller wheels while the suspension is too vague and the geometry too radical to have fun on flow-trails.
- very plush suspension offering lots of traction
- agile in tight terrain
- high-quality finish
- you have to actively weight the front wheel
- the suspension absorbs too much of the rider's input

This scale indicates how efficiently the bike climbs. It refers to both simple and technical climbs. Along with the suspension, the riding position and the weight of the bike all play a crucial role.↩
How does the bike ride and descend? How spritely is the bike, how agile is it through corners, how much fun is it in tight sections and how quickly can it change direction?↩
Is the bike stable at high speeds? Is it easy to stay in control in demanding terrain? How composed is it on rough trails? Stability is a combination of balanced geometry, good suspension and the right spec.↩
This is all about how balanced the bike is and particularly about how well it corners. Balanced bikes require little physical effort from the rider and are very predictable. If a bike is unbalanced, the rider has to work hard to weight the front wheel to generate enough grip. However, experienced riders can have a lot of fun even with unbalanced bikes.↩
How sensitive is the suspension over small bumps? Can it absorb hard impacts and does it soak up repeated hits? Plush suspension not only provides comfort and makes a bike more capable, but it also generates traction. The rating includes the fork and the rear suspension.↩
This aspect mainly comes down to the suspension. How much pop does it have, does it suck up the rider’s input or is it supportive, and how agile and direct is the bike?↩
We don’t calculate value for money in an excel spreadsheet or based on how high-end a bike is specced. We are more concerned with how a bike performs on the trail and how the bike benefits the rider. What good are the best components if the bike doesn’t perform well on the trail? Expensive bikes with a lower-end spec can offer very good value for money – provided they excel where it matters. Just as supposedly cheap bikes with good components can get a bad rating if they don’t deliver on the trail.↩
No, it’s not about racing, it’s about efficiency. Fast, fleet-footed and efficient – those who want to speed along flowy singletrack and gravel roads need a defined and spritely bike that accelerates with ease and efficiency. Nevertheless, reliable components are important too. We interpret XC more like the Americans do: big back-country rides instead of a marathon or XC World Cup with the ultimate in lightweight construction! Uphill-downhill ratio: 80:30 (not everything has to be 100%!)↩
...also known as mountain biking. Classic singletrack with roots, rocks and ledges – sometimes flowy, sometimes rough. For this, you need a bike with good all-round qualities, whether climbing or descending. Uphill-downhill ratio: 50:50↩
Even more extreme and challenging compared to Trail riding, riddled with every kind of obstacle: jumps, gaps, nasty rock gardens, ruts and roots. For this, you need (race)proven equipment that forgives mistakes and wouldn’t look out of place on a stage of the Enduro World Series. Climbing is just a means to an end. Uphill-downhill ratio: 30:70↩
Strictly speaking, a 200 mm travel downhill bike is the best choice for merciless tracks with big jumps, drops and the roughest terrain. Those would be the black or double-black-diamond tracks in a bike park. But as some of the EWS pros (including Sam Hill) have proven, it’s the riding skills and not the bike that define what you can ride with it. Climbing? On foot or with a shuttle, please! Uphill-downhill ratio: 10:90↩
