Dualtron Ultra 2

The Dualtron Ultra 2 is a big, brutal electric scooter that feels closer to a light electric dirt bike than a city toy. It throws out huge power, serious speed, and long range, so it suits riders who want more than a basic commute. This overview walks through how the Dualtron Ultra 2 works and turns the official specifications into plain language you can use.

What Is the Dualtron Ultra 2?

The Dualtron Ultra 2 sits in the extreme performance class from Minimotors. It runs a 72 V system, a big LG battery, and two powerful hub motors. Together they push the scooter into “hold on tight” territory rather than relaxed cruising.

The battery is a 72 V 35 Ah pack that stores around 2,520 Wh of energy. So you get a claimed top speed of about 100 km/h, or roughly 62 mph, on private roads in ideal conditions. On top of that, the brand lists up to 140 km, or about 87 miles, of range in eco riding with a light rider on flat ground.

The frame is built for heavy use. The Dualtron Ultra 2 weighs around 40 kg, which is about 88 lb. It supports riders up to 150 kg, or about 330 lb. So the scooter is anything but light, yet that bulk gives it a planted feel when the motors push hard.

Tires tell you a lot about its purpose. The scooter ships with 11 x 3.9 inch ultra wide off road pneumatic tires. They have deep tread, so they bite into dirt, gravel, and worn asphalt. On smooth pavement they still grip well, although they hum and buzz more than slick street tires.

How the Dualtron Ultra 2 Works

The core idea is simple. You stand on the deck, you pull the trigger throttle, and two hub motors in the wheels pull you forward. There are no chains or belts. So power runs straight from the battery to the wheels through two controllers.

Those controllers act like the scooter’s nerve center. They read the throttle position, battery voltage, and brake signals. Then they decide how much current each motor gets. So the different riding modes do not change the motors themselves. They change how aggressive the controllers act.

On the bars you usually see an EY3 or EY4 display. It shows speed, battery level, trip distance, and modes. Then it lets you tweak settings such as acceleration strength, electronic brake level, cruise control, and sometimes ABS behavior. Once you learn the menu, you can calm the scooter down for city use or let it run wild for off road rides.

Braking mixes hydraulic discs and electronic braking. Each wheel has a hydraulic caliper with a 160 mm rotor. The levers feel smooth at the start, then they bite hard when you pull deeper. At the same time the controller can slow the motors. So when you brake, the scooter turns some of that motion back into electrical energy and sends it to the battery.

Lighting and switches sit close to your hands. You control the front light, turn signals, side LEDs, and horn from simple thumb buttons. So you keep both hands on the grips and still reach every control you need during a ride.

Key Specifications

Here is a clean look at the main factory data for the Dualtron Ultra 2 with the 72 V 35 Ah LG pack. So you can scan the numbers first, then match them with riding impressions later.

So those specifications make it clear. The Dualtron Ultra 2 is built around power, range, and control rather than light weight and quick carrying.

Design & Build Quality

The Dualtron Ultra 2 has a blocky, tough look. The deck is long and thick, since it hides the big 72 V pack and acts as a structural beam. The surface uses rubber or grip tape. So your shoes stay locked in during hard pulls or rough ground. A metal rear footrest extends the deck and gives your back foot a solid brace.

The stem is tall and straight with a chunky clamp at the base. You release that clamp to fold the stem down toward the deck. Then you fold the bar ends. The fold is simple and feels more “industrial” than delicate. So it is not a tiny package, yet it is compact enough to slide into a trunk or along a wall.

Up at the cockpit, there is a lot going on, yet it still feels logical. On the right side you find the trigger throttle and the display, along with mode buttons. Sometimes you see a key switch or an immobilizer puck near the deck. On the left side you have the hydraulic brake lever, lights, turn signals, and horn controls.

Material choice matches the job. The main frame and swing arms use thick aluminum. High stress parts like the steering tube and axles use steel. Plastics cover light housings, side panels, and some trim. So the important load paths stay metal, which gives the scooter a solid, dense feel under your feet.

The whole build leans toward overkill rather than just enough. So if you like scooters that feel rigid and heavy duty, the Dualtron Ultra 2 fits that taste well.

Performance Fundamentals

Twist the throttle for the first time and you feel the character of the Dualtron Ultra 2 right away. In high power dual motor mode the scooter jumps forward with little delay. The front can feel light on grippy surfaces if you lean back too much. So most riders start in lower modes and learn the trigger before they let everything loose.

Once you roll past walking pace, the scooter settles into a strong, smooth pull. Then it keeps that pull going as you move through normal city speeds. The long wheelbase and wide tires help it stay stable when the numbers on the display climb. So bumps that would rattle small scooters feel more muted here.

On moderate hills around 7–10% the Dualtron Ultra 2 barely breaks a sweat in dual motor mode. It holds speed well for a broad range of rider weights. On extreme climbs near its listed limit, it still grinds upward with authority, although speed drops as grade and rider mass stack up. You rarely feel it “run out of motor” in normal use.

Straight line stability stands out too. When the stem clamp is tight and tire pressure sits in a good range, the scooter tracks straight and calm even at higher speeds. Then the wide bar gives you leverage to correct small wobbles before they grow.

So if you ride in a hilly city, or you love fast pulls on open roads, the Dualtron Ultra 2 has more than enough muscle for daily riding and weekend fun.

Battery, Range & Efficiency

The big 72 V 35 Ah LG pack is the star of the Dualtron Ultra 2. It stores about 2.52 kWh of energy, which is huge for a stand up scooter. So it feeds the dual motors without sagging too much even during hard launches and long hill climbs.

On paper you see a range up to 140 km, or roughly 87 miles. Real rides with an adult rider, mixed modes, and mixed terrain usually land lower. In practice, a rider around 80 kg who rides on mostly flat roads, mixes eco and normal modes, and keeps speeds moderate can often expect somewhere around 85–95 km on a full charge. Hard trail play, heavy riders, cold weather, and steep grades pull this number down.

Speed, weight, and surface all matter. Higher speed pushes air drag way up. Heavy riders push more mass, so the motors draw more current. Rough dirt or very soft tire pressure adds rolling drag. So if you plan a long loop with no charging on the way, you plan your pace and surface type while you look at the distance.

Charging takes time. With one standard charger you look at around 23 hours from empty to full. Two standard chargers in the dual ports cut that close to 11 hours. A strong fast charger, used within the limits written for the scooter, plus a standard charger, can bring that down to around 5–6 hours. So if you ride often, adding a proper fast charger is almost a must.

Battery care makes a big difference over the years. So it helps if you avoid storing the scooter for long periods at 100% or at near zero. Mid charge storage is kinder to the cells. Then it helps to let the scooter dry fully after wet rides before you plug in. Good airflow around the deck and controllers keeps temperatures under control during charges too.

You sometimes see Ultra 2 “upgrade” versions with larger packs or different cell types. Those versions tend to stretch real world range, yet the general riding feel of the Dualtron Ultra 2 stays the same.

Ride Quality & Comfort

Ride quality on the Dualtron Ultra 2 feels firm, controlled, and surprisingly friendly once you dial in tire pressure. The 11 inch ultra wide tires carry a lot of air. So they soak up small ripples and cracks in the pavement. On dirt and gravel they dig in and track straight more often than they slide.

The rubber suspension plays a big role. The front unit has a fixed rate. The rear uses adjustable cartridges with five stages. Out of the box many riders find the setup pretty stiff. Then the big tires and the long deck fill in the gaps on deeper bumps and dips. Drops off a normal curb at reasonable speeds feel fine if you bend your knees and keep a good stance.

The deck gives plenty of room. Most people ride with a staggered stance. One foot sits forward, the other on the rear footrest. That stance lets you lean your weight into the bars during hard pulls. For slower trips you can stand side by side on the main deck. The surface grip is strong enough that your shoes do not slide easily, even with some dust on the deck.

Stem behavior is key for comfort and confidence. If the main clamp works loose, you can feel play at the bars and even a hint of wobble at speed. So regular checks of clamp bolts and hinge hardware become part of your routine. When everything is tight, the scooter tracks straight and feels predictable even when speeds climb.

So the Dualtron Ultra 2 rides like a firm, sporty scooter rather than a soft couch. You give up a bit of plush comfort, yet you gain a steady platform when the motors throw serious torque at the ground.

Braking & Safety Features

Strong power needs strong stopping, and the Dualtron Ultra 2 delivers that. The dual hydraulic disc brakes with 160 mm rotors offer a clear, predictable feel. Light finger pressure scrubs speed gently. Deeper pull gives a sharp, confident stop that can bring the scooter down from high speeds in a short distance if the surface has good grip.

Electronic braking layers on top of the hydraulic system. Through the display menu you can pick how strong you want this effect. Lower levels feel like a soft drag that helps on long downhills and saves your rotors. Higher levels kick in hard as soon as you touch the levers and can even feel a bit grabby at walking speeds. So most riders test a few levels and leave it where the scooter feels natural.

The ABS style function pulses the electronic braking to cut down on wheel lock. Some riders like that feeling for straight line stops at higher speeds. Others prefer a softer setting, since high ABS levels can send noticeable vibration into the bars and deck. The nice part is that you can tune it, rather than accept a single fixed setup.

Lighting is better than on many performance scooters. You get a strong front headlight, rear brake light, turn signals, and colorful LEDs along the stem and deck. So car drivers and other riders see you from the front, rear, and sides. Many owners still strap a light on the helmet for night rides, since a head mounted beam points exactly where you look.

Water is the weak spot. There is no clear IP rating from the factory. Light spray and small puddles are common in real use, yet long rides in heavy rain or deep standing water can damage parts and cause warranty trouble. So it pays to treat the Dualtron Ultra 2 as a fair weather machine. Short showers are one thing. Deep flooded streets are another story.

Portability & Daily Usability

Portability is where the Dualtron Ultra 2 asks you to compromise. At around 40 kg, or 88 lb, you are not casually carrying it up three flights of stairs with one hand. Short lifts into a trunk or over a curb are fine if you lift with your legs. Longer carries get tiring fast.

The folding system helps more for storage than for carrying. The stem folds down, the bar ends fold in, and the scooter becomes a long, low package. It still runs around 1210 mm long, but the folded height and width fit better in car trunks and gear rooms. So you can slide it into a wagon, van, or big hatchback without too much drama.

Daily use brings a few habits that make life easier. A scooter this valuable needs serious security. So a hardened chain or strong U lock through the frame and a fixed object is almost mandatory when you leave it outside. Many riders add an alarm and sometimes a hidden tracker. Safe parking spots and simple street sense matter a lot too.

Maintenance needs are regular but not complex. You check the stem clamp and hinge hardware often. Then you keep an eye on brake pads and rotor wear. Tire pressure checks become routine, since these wide tires feel dull and vague when they run soft. They handle better and roll further when they sit in the recommended range.

So the Dualtron Ultra 2 can work as a daily ride. It just works best when you have ground level storage, a garage, or an elevator, not a narrow stairwell in a small apartment.

Dualtron Ultra 2 vs Alternatives

It helps to stack the Dualtron Ultra 2 against a few other types of scooters. First you have regular commuter scooters. A model like the Xiaomi Electric Scooter 4 Ultra weighs much less, folds down small, and tops out at far lower speeds. It is easier to carry, easier to store, and more relaxed in city bike lanes. So it suits short to medium commutes and mixed train or bus trips.

Then look at extreme flagships. A monster like the Dualtron X Limited pushes power, range, and suspension travel even further. It rides like a small electric motorcycle and often weighs well over 60 kg. That class gives more comfort on bad ground and crazy numbers on the spec sheet, yet it is even harder to move, store, and live with day to day.

The Dualtron Ultra 2 sits in between inside the performance world. It hits very high speeds, offers long range, and handles off road riding well. At the same time, it stays lighter and a bit more compact than the heaviest dual stem giants. So for many riders it lands in a sweet spot where power and practicality feel balanced enough.

Compared with pure street performance scooters on slick tires, the Ultra 2 feels more at home on dirt and rough tracks. Street focused models roll quieter on clean asphalt and may feel smoother in straight urban use. The Ultra 2 fights back with better grip on loose ground, stronger hill climbing, and a tougher feel under heavy use.

So if you want brutal power but still care about fitting the scooter in a car or garage, the Dualtron Ultra 2 checks more boxes than both tiny commuters and the heaviest flagships.

Who the Dualtron Ultra 2 Is (and Isn’t) For

The Dualtron Ultra 2 fits riders who know they want a fast, heavy, off road capable scooter and have space to store it. If you dream of long weekend rides on forest roads, gravel paths, or wide suburban streets, this scooter lines up well with that dream. Then it suits heavier riders who sit near or above 100 kg, since the strong motors and 150 kg rating keep speed decent even under load.

It can work as a commuter ride, yet the commute needs to match the scooter. Ground floor homes, garages, or lifts make life easier. Short elevator trips are fine. Carrying the scooter up long staircases every day feels rough. So it slots in best for people who roll it straight out the door, ride, then roll it straight back inside.

For brand new riders, the Dualtron Ultra 2 is a bit much. Power comes in early, and mistakes at high speed hurt more. So a slower model makes a better first step in most cases. After a few months on a calmer scooter, many riders feel ready to jump up to something like the Dualtron Ultra 2 with more respect and better habits.

Students and city riders who rely on buses, trains, and tiny apartments may find it frustrating too. A light 15–20 kg scooter that you can lift with one hand fits that life better. The Dualtron Ultra 2 feels more like a personal “mini bike” for people who already have storage sorted out.

Local law always matters. Many cities cap legal speed for electric scooters and set rules on where you can ride. The Dualtron Ultra 2 normally needs a speed limit set in the display, plus protective gear, to stay within local expectations. So you check your local rules before you blast down public streets.

In short, the Dualtron Ultra 2 is for riders who want serious power, long range, and off road skill in a folding package, and who accept the weight and care that come with that. It is not for riders who just want a light scooter to hop to class or to the corner store.
