Ultra 2

About

If you have been following the electric scooter scene for any length of time, the name "Ultra" likely sends a shiver of excitement down your spine. The original Dualtron Ultra was the machine that effectively invented the high-performance off-road category. It was a raw, unbridled beast that chewed up dirt trails and spat out rocks. Now, we have its successor: the DUALTRON Ultra 2. This isn't just a fresh coat of paint; it is a complete reimaging of what an off-road electric scooter can be, leveraging years of engineering evolution from Minimotors.

The Ultra 2 represents a significant leap forward in power architecture. While many scooters in this class stick to 60-volt systems, the DUALTRON engineers decided to push the envelope by equipping this machine with a 72-volt system. Why does this matter to you? Voltage is essentially the "pressure" behind the electricity. A higher voltage means the scooter can deliver power more efficiently, maintain top speeds even as the battery drains, and provide that punchy, neck-snapping acceleration that enthusiasts crave. It positions the Ultra 2 not just as a fun toy, but as a serious vehicle capable of keeping up with traffic and conquering terrain that would leave lesser scooters stranded.

One of the most clever design choices in this iteration is the relocation of the motor controllers. In the previous generation, and many other scooters, controllers are stuffed inside the deck with the battery, creating a hotbox that can lead to overheating during intense rides. On the Ultra 2, the dual 40 Amp smart motor controllers have been moved to the rear "wing" or footrest. This exposes them to airflow for better cooling, ensuring that you get consistent performance even when you are pushing the machine to its absolute limits up a steep mountain trail. It is this kind of thoughtful engineering that separates Dualtron from the budget brands.

Safety

When you are piloting a machine capable of highway speeds, safety transitions from a "feature" to a necessity. The Ultra 2 is equipped with a hydraulic disc braking system on both the front and rear wheels. Unlike mechanical cable brakes, which can stretch and fade, hydraulic brakes use fluid to transfer force, providing immediate, powerful, and consistent stopping power with just a single finger on the lever. For a scooter that weighs over 40 kg and moves this fast, hydraulic brakes are non-negotiable. The feedback from the levers is excellent, allowing for modulation so you don't lock up the wheels unless you absolutely intend to.

Complementing the mechanical braking is the signature Dualtron Electronic ABS (E-ABS). This system prevents the wheels from locking up completely during emergency braking, which is a lifesaver on loose gravel or wet pavement. If you have never experienced it, it can feel like a strong vibration or pulsing in the wheels when you slam the brakes. While it takes a moment to get used to, it significantly reduces the risk of skidding out and losing control. Furthermore, the sheer size of the 11-inch ultra-wide off-road tires provides a massive contact patch with the ground, offering inherent stability and grip that smaller 10-inch tires simply cannot match.

Visibility has also seen a major overhaul. The Ultra 2 inherits the lighting system from the popular Dualtron Thunder. You get stem lighting, deck lights, and a dedicated tail light/brake light combo. While the integrated stem lights are stylish and help you be seen by cars, serious night riders often find they still need to attach a powerful aftermarket headlight to the handlebars to see the road texture clearly at high speeds. However, the inclusion of turn signals (on the upgraded models) is a welcome addition for urban riding, allowing you to communicate your intentions to drivers without taking your hands off the grips.

Performance

Let's get to the heart of the matter: performance. The DUALTRON Ultra 2 is powered by dual BLDC hub motors that output a staggering peak power of approximately 6 640 Watts. To put that in perspective, your average rental scooter has about 350 Watts. When you pull the trigger on the Ultra 2, the response is visceral. The 72-volt architecture means the torque is instant and relentless. Acceleration is brutal in the best way possible; you need to lean your body weight forward to keep the front wheel planted. This isn't a scooter you simply hop on; it's a machine you pilot.

In terms of speed, the Ultra 2 is capable of reaching upwards of 100 km/h, depending on rider weight and conditions. Realistically, very few riders will spend time at triple-digit speeds, but having that headroom means the scooter feels incredibly relaxed and stable at cruising speeds of 50 or 60 km/h. It's not straining; it's barely waking up. This power reserve is most noticeable when climbing hills. The manufacturer claims a climbing grade of 70% (around 35 degrees). In the real world, this means there is virtually no paved hill in a city environment that will slow this scooter down. It accelerates up inclines where other scooters would stall.

The "Eco/Turbo" and "Single/Dual" buttons on the handlebar allow you to tame the beast for casual riding. However, the community consensus is clear: you buy an Ultra 2 for the "Dual Turbo" mode. The relocated controllers on the rear tail play a huge role here. Because they stay cooler, the scooter doesn't throttle back power due to heat soak nearly as quickly as older models. This means you can enjoy peak performance for longer durations, making it a true weapon for long-distance, high-speed trail riding.

Design

The design language of the Ultra 2 is unmistakably Dualtron: industrial, rugged, and aggressive. It looks like military hardware from a sci-fi movie. The frame is constructed from aviation-grade 6082-T6 aluminum alloy, and the shaft is made of SCM440 steel. Everything about it screams durability. The exposed bolts, the massive swingarms, and the thick stem give it a purposeful aesthetic that doesn't try to be "sleek" or "minimalist." It wears its engineering on its sleeve. The deck is wide and grip-taped, providing ample room for a proper riding stance.

A standout design feature is the rear "spoiler" or kick tail. As mentioned, this houses the controllers, but it also serves a crucial ergonomic function. It provides a raised platform for your rear foot, allowing you to brace yourself against the intense acceleration. Without this solid anchor point, you would feel like you are being pulled off the back of the scooter every time you hit the throttle. The folding mechanism is the classic Dualtron double-clamp system. While it is incredibly strong once locked down, it can be a bit time-consuming to fold and unfold compared to some modern quick-release systems, but the trade-off is a stem that feels welded shut when riding.

The upgraded versions of the Ultra 2 (often called Ultra 2 Upgrade) also feature wider handlebars (685mm compared to the original narrower ones). This might seem like a small detail, but it radically changes the handling geometry. Wider bars give you more leverage and control, making the steering feel less twitchy at high speeds. The inclusion of the new EY4 central display on newer batches brings the cockpit into the modern era, offering Bluetooth connectivity and a much clearer readout of your vitals than the old finger-throttle displays.

Comfort

Suspension is a polarizing topic in the Dualtron community, but the Ultra 2 sticks to the brand's tried-and-true rubber cartridge suspension system. Unlike coil springs which can be bouncy, the rubber suspension absorbs energy through compression. It provides a distinct "damping" feel that makes the scooter feel incredibly planted and stable at high speeds. It eliminates the "speed wobbles" that can plague spring-based scooters. The downside is that it can feel stiff, especially in cold weather or for lighter riders. However, the cartridges are interchangeable, allowing you to swap them for softer or harder compounds to tune the ride to your weight.

The 11-inch ultra-wide pneumatic tires are the unsung heroes of comfort on this machine. Because they are tubeless and hold a significant volume of air, they act as the first line of defense against road imperfections. They swallow up small cracks, gravel, and vibrations before they even reach the suspension arms. Riding on these tires feels like floating on a cloud compared to the harsh ride of solid or smaller tires. The width (approx. 90-100mm) means the scooter doesn't get caught in tram tracks or ruts easily.

Long rides are surprisingly comfortable due to the massive deck space. Being able to shift your feet and change your stance reduces fatigue significantly. The upgraded wider handlebars also reduce the strain on your shoulders and arms, as you aren't forced into a narrow, tense position. While it doesn't have a seat by default (though one can be attached), the standing ergonomics are designed for endurance. You can ride this thing for an hour and hop off feeling energized rather than beaten up.

Range

Range anxiety is virtually non-existent with the DUALTRON Ultra 2. The scooter houses a massive LG battery pack, typically configured as 72V 35Ah or even 40Ah in the upgrade versions, offering a capacity of over 2 500 Wh to 2 880 Wh. The manufacturer claims a maximum range of up to 140 km on a single charge. Now, we must be realistic: manufacturer tests are often done with a light rider, on flat ground, at slow speeds (25 km/h). No one buys an Ultra 2 to drive at 25 km/h.

In real-world usage, riding aggressively in dual motor mode, accelerating hard, and maintaining speeds of 50-60 km/h, you can realistically expect between 70 km and 90 km of range. Even with "hard" riding, that is an incredible distance. It means you can go out for a massive group ride, explore deep into the forest, or commute across the entire city and back without ever glancing nervously at the battery voltage. The 72V system also means the "sag" (drop in performance as battery drains) is less pronounced than on 60V scooters; you keep good power delivery until the very end of the charge.

The caveat to this massive battery is the charging time. With the standard 1.5A charger included in the box, charging a completely empty battery can take upwards of 23 hours. That is a full day. However, the scooter features dual charging ports. By using two standard chargers, you cut that time in half. Better yet, most owners invest in a 5A or 6.5A fast charger, which can bring the charging time down to a manageable 5-6 hours. If you plan to ride daily, a fast charger is an essential accessory purchase.

Use and Practicality

Let's be honest: the DUALTRON Ultra 2 stretches the definition of "portable." Weighing in between 40 kg and 46 kg depending on the specific version, this is not a scooter you want to carry up three flights of stairs to an apartment. It is a heavy piece of machinery. While the stem folds down to make it compact enough to fit in the trunk of a standard car or SUV, lifting it in there is a workout. It is best suited for riders who have ground-level storage, a garage, or elevator access.

As a commuter vehicle, it is overkill for short "last mile" trips, but it excels as a car replacement for medium-distance suburban commuting. If you live 15-20 km from work, the Ultra 2 can get you there faster than a car in heavy traffic, without breaking a sweat. The tubeless tires are generally resistant to pinch flats, which adds to its reliability as a daily driver. However, the stock tires are knobby off-road tires. While they look cool and grip dirt amazingly well, they can be noisy and have less traction on wet asphalt and painted road lines. Many urban commuters swap them for PMT road tires for a smoother, safer city ride.

Storage and security are other practical considerations. Because of its value and "flashy" looks, you cannot simply lock this up outside a grocery store with a cheap cable lock. It attracts attention. It requires a heavy-duty U-lock, a disc brake alarm, and ideally, bringing it inside wherever you go. The EY4 display on newer models offers some password protection, but physical security is paramount for a machine of this caliber.

General Assessment

The DUALTRON Ultra 2 is widely regarded by the enthusiast community as one of the best "pure" electric scooters ever made. It strikes a difficult balance between raw, terrifying power and rideable stability. It doesn't rely on gimmicks; it relies on voltage, amperage, and mechanical engineering. Owners often describe it as a "tank" due to its ability to take a beating and keep going. It has successfully carried the torch from the original Ultra, fixing the main complaints (overheating controllers) while boosting the performance to modern standards.

That isn't to say it is perfect. The suspension, while stable, is stiff and primitive compared to the adjustable hydraulic shocks found on newer competitors like the NAMI Burn-E. The stem folding mechanism, while strong, is an older design that can develop creaks (the infamous "Dualtron wobble") if not maintained properly. However, the sheer availability of spare parts, the massive community knowledge base, and the proven reliability of the drivetrain make it a safer bet than many unproven "spec-sheet monsters" from newer brands.

Overall, the Ultra 2 is a legend for a reason. It delivers an adrenaline rush that is hard to replicate. It feels mechanical, connected, and incredibly powerful. For the rider who wants a machine that can handle a 30 km/h cruise on a bike path and a 90 km/h sprint on a private track, while also being able to climb a dirt trail up a mountain, there are very few machines that can compete with the Ultra 2's versatility.

Who Is This Scooter For?

The DUALTRON Ultra 2 is squarely aimed at the advanced rider and the enthusiast. It is for the person who has perhaps owned a smaller 30 km/h scooter, got bored, and now wants the "endgame" experience. It is for the adrenaline junkie who wants to feel the G-force of acceleration. It is also an excellent choice for heavier riders (100 kg+) who find that smaller scooters struggle to carry them up hills; the Ultra 2 will carry a heavy rider up a steep incline without slowing down.

This scooter is also perfect for the "adventure rider"-someone who wants to explore fire roads, forest trails, and light off-road terrain on the weekends, but needs a vehicle capable of getting them to those trails on the road. It bridges the gap between an urban commuter and a dirt bike. If you enjoy tinkering, upgrading, and customizing, the Dualtron platform is like the Honda Civic of scooters-there are endless aftermarket parts available.

Conversely, this scooter is absolutely not for beginners. The throttle response can be dangerous if you aren't prepared for it. It is not for people looking for a lightweight "last mile" solution to take on a bus or train. It is not for budget shoppers who just want to get from A to B cheaply. This is a high-performance vehicle that requires respect, safety gear (full-face helmet, gloves, pads), and a responsible riding attitude.

Community Feedback - Pros

• Insane Power: The 72V system and dual motors provide acceleration that consistently wows owners.
• Controller Placement: Moving controllers to the rear wing is universally praised for fixing overheating issues.
• Range: Real-world range is massive, allowing for long group rides without charging anxiety.
• Stability: The 11-inch wide tires and firm suspension make it feel planted at high speeds.
• Braking: Hydraulic brakes are sharp and reliable, a massive upgrade over mechanical ones.
• Durability: Owners report the frame and motors are incredibly robust and can take a beating.
• Parts Availability: Being a Dualtron, spare parts and upgrades are easy to find globally.
• Rear Footrest: The integrated rear wing provides excellent leverage for acceleration.
• Classic Look: Many users love the industrial, aggressive aesthetic that defines the brand.
• Lighting Upgrade: The inclusion of stem and deck lights (similar to the Thunder) is a well-liked improvement.

The community most frequently praises the power-to-reliability ratio. While there are faster boutique scooters, the Ultra 2 is seen as a workhorse that delivers elite performance without constantly breaking down. The relocation of the controllers is frequently cited as the "game changer" that allows riders to push the scooter hard for extended periods without hitting thermal throttling, which was a major pain point on the original Ultra.

Community Feedback - Cons

• Charging Time: taking nearly 24 hours to charge with the stock charger is a major complaint; a fast charger is considered a mandatory extra purchase.
• Weight: At 40kg+, it is extremely heavy and difficult to maneuver when not riding.
• Stiff Suspension: The rubber suspension is often described as too hard for lighter riders, leading to a bumpy ride on rough surfaces.
• Stem Creak: The classic Dualtron stem wobble or creaking sound often develops over time and requires maintenance/tightening.
• Stock Tires: The knobby off-road tires are noisy and slippery on wet pavement; many users swap them immediately for road tires.
• No IP Rating: Lack of an official water resistance rating makes riders nervous about riding in the rain.
• Single Stem Clamp: Some users feel the folding clamp design is dated compared to newer, more rigid locking mechanisms.
• Price: It is an expensive investment compared to some "spec-sheet" competitors from newer Chinese brands.

The most consistent gripe involves the suspension stiffness and the stock tires. Many users find that out of the box, the scooter is set up for very aggressive off-roading or very heavy riders. Lighter riders often feel every bump in the road until they break in the suspension or swap the cartridges. Additionally, the lack of a fast charger in the box for a battery of this massive size is frequently mentioned as a "cheap" move by the manufacturer given the premium price of the scooter.

Value for Money

With a price tag hovering around 3 541 €, the DUALTRON Ultra 2 is undeniably a premium purchase. It sits in the upper echelon of the scooter market. Is it worth it? If you value brand heritage, parts availability, and proven engineering, the answer is generally yes. When you buy a Dualtron, you are buying into an ecosystem. You know that if you need a new motor or a control arm in three years, you will be able to find it. That peace of mind has a monetary value that cheaper, "here today, gone tomorrow" brands cannot offer.

However, strictly looking at specs-per-euro, the competition is fierce. Brands like Kaabo and NAMI offer scooters with similar speed and range for potentially lower prices, often including features like TFT screens or adjustable hydraulic suspension out of the box. The Ultra 2 charges a "Dualtron Tax," but in exchange, you get a machine with higher resale value and a finish that generally holds up better over time. You are paying for the refinement of the 72V powertrain and the reliability that comes with the Minimotors name.

Ultimately, the value proposition is strong for the rider who plans to keep the scooter for a long time and ride it thousands of kilometers. The initial cost is high, but the robustness of the frame and the quality of the battery cells (LG) mean the cost of ownership over time is reasonable. It's an investment in a serious vehicle, not a disposable toy.

About the Brand

Minimotors, the parent company of DUALTRON, is essentially the "Godfather" of the high-performance electric scooter industry. Founded in South Korea in 1999, they have been building electric motors and vehicles far longer than the current trend of e-mobility has existed. They launched the first Dualtron in 2015, which was the first all-wheel-drive electric scooter, effectively creating the category of "hyper-scooters."

The brand has a reputation for building "tanks." Their philosophy centers on extreme performance and durability. While other brands might focus on app integration or sleek futuristic curves, Dualtron focuses on how many thousands of watts they can reliably put through a wheel. They are the benchmark against which all other fast scooters are measured. If a new scooter comes out, the first question is usually, "Is it faster than a Dualtron?"

Customer support and community for Dualtron are arguably the best in the world. Because they have been around the longest and have the largest market share in the high-end segment, there are endless YouTube tutorials, Facebook groups, and local repair shops that know how to work on them. This global network is a massive asset. If you are interested in high-performance mobility, you owe it to yourself to check out the full lineup of DUALTRON scooters, as they offer everything from compact city commuters to 100 km/h racing machines.

Known Alternatives

If the Dualtron Ultra 2 is on your radar, you are clearly looking for high-end performance. However, it's always smart to shop around. One of the most direct competitors is the KAABO King GT Pro. The Kaabo is often cited as the primary rival to the Dualtron line. It features a similar 72V system and massive speed, but it differentiates itself with a dual-stem design (very stable) and fully adjustable hydraulic suspension, which offers a plush ride out of the box. It also comes with a gorgeous TFT display that many find superior to the standard Dualtron eye throttle.

Another alternative within the same family is the DUALTRON Thunder 2 EY4. The Thunder 2 is more focused on street performance compared to the Ultra's off-road heritage. It typically comes with even more power (peak 10 000W on some specs) and road-focused tires. If you know you will never touch the dirt, the Thunder 2 might be the better asphalt assassin, offering similar range and build quality but optimized for the tarmac.

Finally, for those looking for modern features, the MUKUTA 10 Plus is gaining traction. While slightly lower in raw voltage compared to the 72V beasts, Mukuta (often linked to the factory that builds Zero/Vsett) offers incredible value for money, often including features like removable batteries or advanced suspension geometries at a competitive price point. It's a great option if the Ultra 2 feels just a bit too industrial or expensive for your needs.
