The Ibis HD5 sits in that narrow space between old-school 27.5 fun and modern enduro aggression. It is a carbon DW-link bike with 153 mm of rear travel and a 170 mm fork, so the real question is not just what it was, but what it still offers in 2026. In practice, that means looking at the geometry, the ride feel, the setup details, and the realities of buying a discontinued frame in the UK.
What you need to know before choosing one
- It was sold from 2019 to 2021 and is now a past model, so most buyers will be shopping used.
- Core numbers are simple: 153 mm rear travel, 160-170 mm fork, 27.5" wheels, 64.0° head angle, 75.8° seat angle.
- The ride character is playful and responsive rather than long-legged and ultra-planted.
- It uses a threaded bottom bracket and Boost spacing, which helps long-term ownership.
- HD6 is the obvious modern benchmark if you want more travel, mixed wheels, and current-geometry stability.
What the Mojo HD5 is and why it still matters
The Mojo HD5 was Ibis’ hard-charging 27.5 enduro platform, built for riders who wanted a bike that could climb honestly and descend with real intent. I read it as a compact, aggressive carbon frame rather than a bruiser in the modern “point it and forget it” sense. That distinction matters, because the bike’s value in 2026 comes from feel as much as from numbers.
It was produced for the 2019-2021 model years, and that tells you a lot. Geometry was already moving in a longer, slacker direction by then, but the HD5 stayed committed to 27.5 wheels instead of chasing mixed-wheel trends. The result is a bike that still feels lively in tight terrain, especially if your local trails are steep, rooty, and full of awkward direction changes.
One thing I like about the platform is that it never pretended to be a trail bike with a big fork bolted on. It is an enduro machine with a clear personality: quick to move, supportive under power, and willing to carry speed without feeling dead. To understand why that still works, the numbers are the next place to look.
The spec sheet that defines the bike
The headline spec is straightforward, but the details explain the character. The frame is carbon monocoque, the rear end delivers 153 mm of travel, and the bike is designed around a 170 mm fork. Ibis’ DW-link suspension keeps pedalling efficient while preserving traction, which is why the HD5 can still feel composed on climbs even though it is clearly built for descending.
| Spec | HD5 |
|---|---|
| Years sold | 2019-2021 |
| Frame | Carbon fibre monocoque |
| Rear travel | 153 mm |
| Fork travel | 160-170 mm, designed around 170 mm |
| Wheel size | 27.5" |
| Shock size | 200 x 57 mm / 7.875 x 2.25" |
| Head angle | 64.0° |
| Seat angle | 75.8° |
| Chainstays | 430 mm |
| Bottom bracket | 73 mm threaded BSA |
| Tyre clearance | Up to 2.6" |
| Sizes | S / M / L / XL |
| Frame weight | 5.6 lb frame only on a size large |
A few ownership details matter just as much as the headline geometry. The frame uses Boost spacing, a 31.6 mm seatpost, a 180 mm post-mount rear brake with room for a 203 mm rotor, and an optional ISCG 05 tab adapter. In plain English, that means the bike uses mainstream standards and is easier to live with than many older enduro frames. The threaded bottom bracket is especially welcome; I would always rather service a bike like this than fight with a creaky press-fit shell.
Traction Tune is another important piece of the puzzle. It is Ibis’ softer, grip-focused damping approach for the front and rear suspension, aimed at keeping the wheels moving quickly over rough ground. Combined with DW-link, it helps the bike feel supportive without becoming harsh. That is the kind of setup that makes sense on real trails, which brings us to how the bike actually rides.
How it rides on steep, wet, technical trails
I would describe the HD5 as compact, active, and confident rather than calm. The 27.5 wheels and 430 mm chainstays make it easy to load into a corner, unweight off roots, and change line late. On steep UK trails that can be a real advantage, because the bike reacts quickly and does not ask you to wrestle a long rear centre through every switchback.
- On climbs, the steep 75.8° seat angle keeps your weight in a sensible place over the bike, and the DW-link layout helps the rear end stay efficient instead of bobbing around.
- On descents, the chassis feels eager rather than sluggish. It likes to be pushed into turns and popped off trail features, which is exactly why some riders still prefer 27.5.
- On faster, rougher lines, the shorter wheelbase and older enduro geometry give away some calm compared with newer mixed-wheel bikes. That is not a flaw so much as a trade-off.
My read is that the HD5 suits riders who want feedback and playfulness more than maximum stability. If your local trails are tight, rooty, and full of off-camber turns, that personality can be a genuine advantage. If your weekends are more about high-speed race stages and long rough chutes, a newer platform will feel less busy under you. Fit is the other half of that equation, because the wrong size can make a lively bike feel nervous.
Fit and setup details that affect the ride more than you think
This is one of those bikes where I would choose by reach feel, not height alone. The frame sizes are straightforward, but the overlap between sizes means riders can easily end up on something too short if they chase only standover or a familiar number from another bike.
| Size | Typical rider height | Reach | My take |
|---|---|---|---|
| S | 152-163 cm | 427 mm | Best for smaller riders or anyone who wants the shortest cockpit |
| M | 163-173 cm | 447 mm | Balanced and easy to live with |
| L | 170-185 cm | 472 mm | The safest all-round choice for many riders |
| XL | 183-196 cm | 503 mm | Longest and most stable option |
There are a few setup notes I would treat as non-negotiable. Small and medium frames came with 170 mm cranks and a 40 mm stem, while large and extra-large bikes used 175 mm cranks and a 50 mm stem. The bike is not mullet compatible, so I would not plan on converting it to a mixed-wheel layout. It was designed around 27.5" wheels from the start, and that simplicity is part of the appeal.
- Maximum chainring size is 34T.
- The recommended oval chainring size is 32T.
- A 22 oz bottle fits with the right side-loader cage.
- Clevis-compatible coil shocks can work, but compatibility should be checked carefully before buying.
- The 73 mm threaded BB is a plus if you value easy maintenance.
Those may sound like small details, but they shape day-to-day enjoyment more than most buyers expect. Once fit is right, the next question is whether buying one second-hand in 2026 still makes sense.
What to check before buying one used in 2026
Because the HD5 is discontinued, I would only buy one if the frame and linkage are genuinely clean. The good news is that replacement hardware and protection parts are still listed for the platform, so ownership is not a dead end. The risk is less about obsolete standards and more about the usual used-enduro problems: wear, bad maintenance, and a seller who has not bothered with service records.

What I would inspect first
- Lower-link play and any looseness in the shock hardware
- Chain-suck marks, downtube damage, and heavy chainstay wear
- The rear hanger, axle condition, and any signs of crash damage around the dropout area
- The shock model and whether it matches the frame’s clevis requirements
- Fork, wheel, and tyre clearance at full compression, especially if the bike has unusual parts fitted
- Any hidden import cost if the bike is coming into the UK from overseas
For a UK buyer, that last point is easy to underestimate. A bike that looks cheap on a classifieds site can stop being a bargain once shipping, duties, and a refresh of worn suspension parts are added in. I would rather pay a fair local price for a well-kept frame than gamble on a cosmetic bargain with a tired shock and sloppy linkage. Once you know what you are getting, the comparison with the newer platform becomes much clearer.
HD5 versus HD6 and the decision I would make
The HD6 is the obvious modern reference point because it carries the same aggressive Ibis DNA in a fresher shape. It is mixed-wheel, longer travel, and built for a more contemporary enduro race brief. That does not make the HD5 obsolete; it just means the decision is now about feel, not fashion.
| Feature | HD5 | HD6 | Why it matters |
|---|---|---|---|
| Wheel format | 27.5" | 29 / 27.5" mixed | HD6 carries more speed and stability; HD5 feels more playful |
| Rear travel | 153 mm | 165 mm | HD6 has more reserve for bigger hits |
| Fork travel | 170 mm | 180 mm | HD6 is aimed at harder enduro terrain |
| Head angle | 64.0° | 64.0° | Front-end calm is similar on paper |
| Seat angle | 75.8° | 76-77.5° | HD6 puts the rider even more centrally for climbing |
| Chainstays | 430 mm | 435 mm | HD5 feels a touch shorter and more compact |
| Frame weight | 5.6 lb frame only | 7.7 lb frame with shock | More travel and mixed wheels add heft |
| Status | Past model | Current model | HD5 is a used-bike decision; HD6 is a new-bike decision |
If I were buying for steep, technical UK riding and wanted the most playful feel, I would still consider the HD5 seriously. If I wanted the safer all-round bet, especially for faster enduro days or rougher alpine-style terrain, I would move to the HD6 without much hesitation. That is really the heart of the choice: the older bike wins on personality, while the newer one wins on margin for error.
The sweet spot it still fills in 2026
The HD5 still makes sense when the rider values feel over fashion. A clean frame with serviced suspension, no linkage play, and enough budget left for fresh bearings, tyres, and a proper setup can still be a very smart buy. I would not chase it for pure numbers alone; I would buy it because it makes steep, awkward terrain feel more playful and more manageable.
That is the bike’s real value now. It is not trying to be the latest thing, and that is exactly why it still earns attention from riders who want a compact, capable enduro frame with a distinctive ride character. For the right rider, especially one shopping the used market in the UK, the HD5 is still easy to justify.
