Exclusive Test: New UNNO Mith Pro with DJI Avinox motor – Is This the Future of eMTBs?
Is this bike the end of the light eMTB segment as we know it? UNNO are among the first brands worldwide to build a frame around the DJI Avinox motor, which only made its debut a year ago. It tips the scales at just 21.5 kg despite using a massive 800 Wh battery, and combines 170/160 mm of travel with a mullet wheel setup and chunky tires – it all sounds like pure downhill fun. But does the concept actually deliver?

The Ferrari of eMTBs? It may not come in Rosso Corsa, but the UNNO Mith with DJI Avinox drive turns heads with its bold, distinctive look and a raw carbon finish. Sexy, sleek, powerful, lightweight… it ticks all the boxes of a high-end sports machine.
But let’s not get ahead of ourselves. As the only magazine worldwide to test the new UNNO Mith Pro ahead of its official launch, we took it through its paces in the Ligurian Alps, on the trails around Barcelona, and back home in Stuttgart. On top of that, we made a dream come true for one lucky E-MOUNTAINBIKE reader, inviting him to join us for an exclusive test ride in Barcelona. Before the bike was even released, Brodie flew in from the UK to put the new Mith Pro through its paces – alongside E-MOUNTAINBIKE founder Robin Schmitt and Mr. UNNO himself, former World Cup DH racer César Rojo – on some of the region’s best trails.
What’s new on the UNNO Mith Pro?
Originally, César Rojo developed the new UNNO Mith around Bosch’s Performance Line CX Gen 5 motor and logged over 2,500 km on the prototype. But then DJI entered the market– and it quickly became clear: if not now, when? So he made the bold decision to switch motor systems. The integration possibilities, ride dynamics and range of the Avinox system won him over. And since he already had a near-production-ready prototype, he was able to bring the new Mith with DJI motor to market in a remarkably short time.
Compared to the previous UNNO Mith with Bosch CX Race motor, the new version brings more than just a different drive system. It also includes several key updates,some of which existing UNNO fans were initially sceptical about. The five biggest changes:
- Increased seat tube insertion depth for longer dropper posts
- A more minimalist, refined frame design
- Easier shock access and revised kinematics
- Larger, more robust rear triangle bearings
- A revised size chart to reduce the jumps between S1, S2, and S3
Also worth noting: you can now easily fit a 750 ml bottle inside the front triangle. As with the previous UNNO Mith, the battery is not removable.
When it comes to weight, the new UNNO Mith Pro with DJI motor has shed over a kilo compared to the previous Mith with the Bosch CX Race system. That puts it firmly in competition – not just visually, but across the board – with most light eMTBs currently available on the market. In short: with a fully integrated 800 Wh battery and a total system weight of just 21.5 kg in size S2 (~M), the new Mith means you no longer have to choose between a light eMTB or a full-power machine.
That’s the theory, at least… But is this sleek new carbon bike really worth the €11,995 price tag? Or is it more of a showpiece destined for the Museum of Modern Art? We put it to the test to find out.
What sets the new UNNO Mith Pro with DJI Avinox Motor Apart From the Competition?
Honestly?! It’s hard to believe that there’s an 800 Wh battery hidden in there. The downtube of the UNNO Mith Pro is slimmer in diameter than that of most light eMTBs. And right away it becomes clear: this is no off-the-shelf e-bike. The bold, aggressive design with the heavily sloped top tube and striking seat dome stands out clearly from the crowd. The integrated seat clamp with rubber cover eliminates the need for a traditional collar and makes it possible to use the distinct D-shaped seat post in the first place.
The slim frame silhouette, paired with the black raw carbon finish in a honeycomb pattern, gives the bike a premium look while proudly showing off its core material. Also gone are the days of complicated headset cable routing that the previous Bosch-powered Mith employed. The cockpit is clean, and all the cables enter the frame through integrated ports next to the head tube, specifically designed for an electronic drivetrain and mechanical dropper. This means that retrofitting a mechanical drivetrain – like SRAM’s new Eagle 90 Transmission – is not an option. The reason? The cables run neatly along the battery, helping keep the downtube so impressively slim.
The DJI Avinox M1 motor is integrated very discretely, too. With up to 120 Nm of torque in Boost mode (limited to 30 seconds), 105 Nm in Turbo mode, and 1,000 watts peak power, it’s one of the most powerful drive units currently available in the eMTB sector – despite its compact size and low weight. But, as we’ve already noted in earlier tests, it’s not the sheer power that makes this system so good – it’s the level of control and responsiveness.
The motor draws its power from a fully integrated 800 Wh battery. The non-removable design helps reduce frame weight while at the same time increasing stiffness. On the other hand, this means that you can’t charge the battery externally. On the bright side: the included 12-amp fast charger gets you a full charge in about 145 minutes – enough for an 80% charge during a long lunch stop, getting you back out on the trail in Turbo mode for the next run. The charging port is positioned just above the motor, where it’s easy to access and well protected from dirt.
When it comes to user interface and connectivity, DJI set the bar high: a fully-customisable 2″ OLED display is built into the top tube, displaying all essential ride data. It also features a USB-C port for charging your smartphone or bike computer while riding. Control comes via a glove-friendly touch display and two wireless bar remotes. The companion app includes a range of features like GPS tracking, anti-theft alarm, ride data analysis, and motor customisation – an excellent addition for tech-savvy riders.
The frame features a a bottle cage mount on the downtube and a tool mount under the top tube, allowing you to hydrate well on long rides, and to carry out basic trailside repairs. A generously sized rubber chainstay protector covers both the stay and the underside of the lower link, preventing chain slap and thus ensuring a quiet ride on the trail. A small rear fender helps protect the horizontally mounted shock from muck and stray rocks.
UNNO also improved frame protection compared to the pre-production prototype we tested previously. While those parts were still 3D-printed, the final bike uses components like the bash guard and covers made from talc-reinforced polypropylene – designed to be extra tough and impact resistant.
The spec of the new UNNO Mith Pro with DJI Avinox motor
Our pre-production test bike differs slightly from the final production model, which is fully performance-oriented and tuned for downhill action. The suspension consists of a FOX 38 Factory GRIP X2 fork and a new FOX FLOAT X2 Factory air shock – our test bike still had the Performance Elite version. The suspension controls 170/160 mm of travel at the front and rear, respectively, and offers countless adjustment options on both high- and low-speed compression and rebound. The shock also includes a climb switch to lock out the rear end for more efficient pedalling on climbs. The OneUp V3 dropper post offers a solid 180 mm of travel in size S2 (~M) and rightly earned its place as the reliable test winner in our sister magazine ENDURO’s big dropper post comparison test. OneUp also supply the carbon cockpit. Shifting is taken care of by a wireless SRAM X0 Eagle AXS Transmission drivetrain, which relies on a direct-mount rear derailleur and deliver butter-smooth gear shifts even under load. Formula Cura 4 four-piston brakes with 203 mm GALFER rotors provide powerful, reliable deceleration. A smart touch: the rear rotor features built-in slots for the speed sensor – no need for a separate sensor ring!
The production version of the Mith rolls on a NEWMEN PHASE 30 carbon wheelset – Base at the front, Strong at the rear. Our test bike came with robust DT Swiss HX1700 aluminium wheels. The tires are on point: Schwalbe Magic Mary front and rear, both with Super Gravity casing. Up front you get the soft Ultra Soft compound, while the rear runs the more durable Soft compound – a great balance of grip up front, longevity at the rear, and added rim protection.

The different spec versions of the new UNNO Mith with DJI Avinox motor system
Alongside the UNNO Mith Pro top-tier model, the Catalan boutique brand also offers the Mith in a Race version, which features a very sensible spec with more robust components and fewer carbon parts. At €9,995, it’s exactly €2,000 less than the Pro model.
The UNNO Mith Race relies on the same FOX 38 GRIP X2 Factory fork but employs a FOX FLOAT X Factory shock, which offers slightly less adjustability than the new X2 model, but still performs at a very high level. UNNO also use the same OneUp V3 dropper post, which provides 150, 180, and 210 mm of travel depending on frame size – S, M, or L respectively. The carbon OneUp cockpit is replaced by an aluminium version in the Race build. Shiftingis taken care of by a wireless SRAM S-1000 Eagle Transmission drivetrain, which is slightly slightly heavier than its top-tier counterpart and also features a simpler finish. Braking is handled by the same Formula Cura 4 four-piston brakes as on the Pro model. However, instead of the GALFER rotors with integrated speed sensor slots, the Race model uses standard 203 mm Formula rotors front and rear, paired with a separate speed sensor ring. The Race build swaps the carbon rims of the high-end model for NEWMEN PERFORMANCE aluminium wheels – Base in the front and Strong in the rear. The tires are the same: Schwalbe Magic Mary front and rear, with Super Gravity casing, Ultra Soft compound up front and Soft compound at the rear.
Für alle, die nicht auf Performance verzichten, aber etwas Budget sparen wollen, ist das UNNO Mith Race eine super solide Variante.
The geometry of the new UNNO Mith with DJI Avinox motor system
The UNNO Mith is available in three frame sizes, S1, S2, and S3 (roughly equivalent to S, M, and L), offering a suitable option for riders between 165 and 200 cm tall. Reach values vary between 430 mm (S1), 460 mm (S2, our test bike), and 490 mm (S3). Particularly striking are the still relatively large jumps in reach between sizes, which can make it harder to choose the right size – especially if you’re on the fence between two sizes. That said, the previous model had even bigger gaps, and riders between S1 and S2 now have a better chance of finding a good fit. Despite its distinctive seat dome, the seat tube is a moderate 420 mm, offering plenty of freedom of movement on descents. The slack 63.5° head angle aims to maximise stability, while the steep 77° seat angle is designed to support efficient climbing – though, as we’ll see in practice, geometry isn’t everything. Chainstays come in at a relatively long 450 mm and do not change across frame sizes. A nice detail: even in size S, the frame still accommodates the large 800 Wh battery.

How did the UNNO Mith Pro fare in our test?
As the first magazine worldwide to ride the UNNO Mith, we put the bike through its paces over a three-month period before its official release – and even had the chance to actively contribute to its development. Following our feedback, César Rojo’s team at UNNO adjusted one of the linkage points to reduce the bike’s anti-squat characteristics. But let’s start from the beginning.
The UNNO Mith Pro impresses on the climbs with a comfortable riding position. The high front end encourages an upright pedalling position, which relieves pressure on the wrists – perfect for long gravel road climbs. The sensitive suspension absorbs small bumps effectively, adding plenty of comfort without noticeable pedal bob. The powerful DJI Avinox M1 motor supports you continuously, staying pleasantly quiet while delivering smooth, well-modulated power. Even at low cadences, the motor provides strong assistance, allowing you to cruise up fireroads close to the 25 km/h limit with ease.
The new UNNO Mith is like a two-wheeled supercar – fast, striking, and sexy. If you want to ride it right, you’ll need skills – but the reward is massive!
But once the climb turns steep and technical, the Mith demands more input from the rider. Because of the high front, you’ll have to actively shift your weight forward to keep the front wheel tracking. Despite the motor’s excellent traction and the grippy tires, it becomes clear that the suspension is designed primarily for descending. If your priority is taking on nasty tech climbs, DJI’s other debut bike – the AMFLOW – might suit you better. Finding the right balance between front and rear is key to maintaining grip and steering precision. Fortunately, the motor is low-maintenance in that regard – it delivers smooth, even power at both low and high cadences, without responding too abruptly. On steep climbs, the optional Boost mode gives you an extra 30-second surge of power.
When gravity takes over and the trails open up, the UNNO reveals its sharp, precise handling. It responds quickly to steering input and tracks accurately through corners. On flatter, open turns, however, the bike demands a more active riding styleand a bit of an adjustment period. You’ll need to shift your weight, stay centred, and keep pressure over the front wheel – similar to what’s required in steep climbing sections. Once you’ve got the balance dialled in, the stiff suspension lets you build speed easily by pumping terrain features or popping off kickers. We tested different sag settings between 25% and 30%. UNNO recommend 30-35% sag, with the upper end optimised for downhill performance.
The bottom line: the UNNO Mith Pro isn’t a bike you just hop on and go full-send – unless your name is Brodie, our lucky test rider. For most riders, it takes 2 to 5 rides to really get in sync with the bike’s character,but once you do, it takes off like a rocket.
With an experienced rider, the UNNO Mith Pro comes alive and turns into a true trail weapon.
On steep and rough terrain, the Mith Pro fully comes into its own. The suspension is firm enough to handle big hits but still plush enough to maintain traction. The low riding position and high front end offer tons of control and confidence – even at speed and on technical descents. It feels composed, holds your line asif on rails, and can still be guided precisely through rock gardens. At high speeds, the Mith requires more rider input to change direction, but rewards you with direct feedback, momentum, and a lively ride feel. Once you understand its character, the bike invites you to push harder – and pushes you in return. It’s a fun-loving beast for experienced riders looking for a fast, demanding machine that makes even the gnarliest trails feel manageable. So… do you have the confidence to take on the UNNO Mith?
Who should take a closer look at the UNNO Mith Pro?
The UNNO Mith Pro is built for committed riders with a strong focus on performance. It’s aimed at eMTBers who enjoy technical, demanding trails and bring an active riding style to match – those looking for a bike that offers high levels of composure and precision. If you’re willing to ride the bike actively and push yourself, you’ll be rewarded with top-tier performance and a sharp, responsive ride feel.
It’s less suited to riders who prefer relaxed cruising or prioritise everyday versatility and all-round practicality. If you’re looking to sit back and let the bike do the work, the Mith won’t be the right fit – and you’ll miss out on the true potential it has to offer.
How much motor power is enough? The peak power race with S-Works 3.1 and DJI Avinox M1
Since the launch of the DJI Avinox M1, a new hype has emerged around maximum power and torque – and we get the excitement. More always sounds better, right? Same with cars. But long-term, this trend could backfire, and we believe it’s time to settle on a more reasonable level.
More power and torque also mean more wear and tear, more stress on the motor system, and – especially in steep terrain or depending on the assist mode– significantly less range than you’d expect, even with big batteries. What we need to avoid at all costs is a future where batteries keep getting bigger and bikes heavier, just to deliver range for support modes most riders don’t even use.
Specs might sell bikes – but in the end, traction control and power modulation are far more important than raw output.
Conclusions about the new
UNNO Mith Pro
The UNNO Mith Pro isn’t a bike for everyone – it’s made for seasoned trail veterans with an active, playful riding style, especially downhill. Supported by the powerful Avinox motor, the new Mith is a bold evolution of its predecessor and shows just how far eMTB tech has come – and where it’s heading. Premium components, smart details, and a striking, forward-thinking design all reflect its high-performance ambitions.
