Monster Truck of Electric Scooters

On my very first ride, I can still remember the feel of the handlebars, the weight of the chassis, the firm 11″ off-road tires, and the moment I felt the thrust of acceleration after pulling the throttle; it made me feel like I was riding the Monster Truck of Electric Scooters. Ten minutes later, I was plowing through an empty field, traversing the bumpy, uneven gravel; it finally hit me; the Ultra 2 was the real deal.

My First Impressions on the 2021 Dualtron Ultra 2

There are so many words I can use to describe the Ultra 2. It’s big, bold, loud, heavy, strong, powerful, and fast; it’s an absolute beast! This isn’t your run-of-the-mill Lime rental electric scooter, and it isn’t pretending to be… this is the Dualtron Ultra 2, one of the most robust electric scooters on the market! The Ultra 2 is many things, my car, bus, subway, stress reliever, hot rod, rocket-ship, all above! A “quick grocery store trip” can take 3 hours.

Dualtron Ultra 2 Quick Facts and Performance Tests:

• Cruising Speed: 30-40 MPH Easily
• Top Speed: +55MPH with off road tires on very windy day, will retest with PMT Road tires in better weather conditions
• Battery Range depends on performance settings: Low settings (40-60 Miles), Mid Settings (30-40 Miles) High Settings (30-40 Miles)
• Comfort & Handling: Very comfortable & secure ride, firm suspension for high speed
• Weight: Heavy Scooter, not easy to lift up stairs if needed
• Build Quality: High quality build and chassis
• Tires: Knobby great for off road and uneven pavement
• Recommended upgrade for enthusiasts who ride 30-45MPH scooters.
• Not recommended for absolute beginners, learn how to ride on smaller scooters first!

I’ve personally owned 3 Dualtrons (Dualtron Mini, Dualtron Eagle, Dualtron Ultra 2); for anyone interested in my experience with Dualtrons, check out my Dualtron Shopping Guide for information on the 2021 models and my Dualtron owner’s guide to help riders know what to expect for upgrading and maintaining their electric scooters! Currently, I’m working on an entire drivetrain rebuild project on the Eagle Pro; make sure to subscribe to the newsletter for more information!

The Legend Continues

In September 2020, the first leaked Dualtron Ultra 2 photos made a ripple through the forums and generated excitement and anticipation in the electric scooter community.

When I first laid eyes on the Ultra 2, the classic Dualtron frame, it’s knobby tires, the new rear wing external controller… I was smitten. I had to have one!

Fast forward to 6 months later, I was ready for my next electric scooter upgrade (I had already started purchasing Ultra 2 aftermarket parts) and was planning to keep the Eagle Pro as my daily commuter and ride the Ultra 2 for the big group rides. After a few email exchanges with John (MiniMotors USA), his February shipment arrived, and my Ultra 2 was already on its way to New York City!

The Dualtron Ultra 2 Build Quality

The 2021 Dualtron Ultra 2 is the 2nd generation (3rd major iteration) of the Dualtron Ultra series. Based on its 2nd Gen chassis, the Ultra retains its classic look, structure, suspension, and off-road capabilities. Design-wise, the Ultra 2 is the spitting image of the Ultra 1. Inheriting most of the Dualtron Thunders’s premium features, the Ultra 2 is upgraded with folding handlebars, hydraulic brakes, LED lighting, and more (we’ll go through each element below).

Coming in at 88 lbs, the Ultra 2 is a heavy scooter (for a good reason); it’s capable of a +62 MPH top speed. The Ultra 2 carries a pair of 11″ motors and a 72V battery pack and is built on a heavy-duty (aviation-grade) aluminum chassis.

The Ultra 2 chassis is built to go the distance, whether if its on road or off road.

Pre-Ride Scooter Check List

When unboxing and configuring the scooter, I noticed that all of the critical structural components (headset, stem, folding clamp, handlebar, brake calipers) were secure and tight, and no loose parts or wobble could be found. The quality control on my Ultra 2 was on point; I ensured the tightening/torque of any visible bolts before my maiden voyage.

How Does the Dualtron Ultra 2 Perform?

The Ultra 2 is one of the first electric scooters to feature an external 40-amp controller/footrest. This design choice allows for better controller heat dissipation and deck space to accommodate its massive 2,520WH LG battery pack.

Boasting a MAX 6,640-watt BLDC dual hub motor, this scooter’s drivetrain will gobble up any current. One huge improvement is that MiniMotors removed the single/double motor switch; the Ultra 2 only operates in dual motor mode!

Economy Mode

EYE Throttle Settings (P7:0 P8: 100 P9:3)

My first ride experience was unreal; I was able to hit 30 MPH in gear 1! To put that speed metric in perspective, the Dualtron Eagle Pro averages 30 MPH in its highest settings (nonturbo). When it came to torque, I didn’t understand how vital the Ultra 2 is until I experienced the butt-clenching acceleration; I needed a drink and cigar after my first ride experience.

Turbo Mode

EYE Throttle Settings (P7:0 P8: 100 P9:3)

The Ultra 2 is the evolution of Dualtron performance. After finding an open stretch of road, I maxed out the settings and lightly pulled the throttle … to my utter shock; I found the front motor lifting off the ground; just barely tugging the throttle, I was already on my way to hitting wheelies!

The external controller design is absolutely brilliant!

Not to mention, the controller/footrest is absolutely clutch. When the torque pulls you forward, you’ll find your rear foot digging into the footrest to retain your balance. Living in New York City, riding with the top performance settings is not advisable, especially with pedestrians, cyclists, red lights and stop signs on every corner.

Cruising & Top Speed

For cruising speeds, dialing the settings to ECO and P9:1 is more than enough power for any inner-city riding. Through the neighborhoods of Astoria and Queens, 20-25 mph is a safe speed for the internal city grid structure.

The Ultra 2 is pure power, at 84V when fully charged, the throttle can be very sensitive.

Recommended settings for beginners – P7: 5, P8: 70, P9:1

Throttle Gear Settings: For beginners, use gear two on the throttle display. The gears are speed governors that will place a cap on your top speed. On New York City streets, you won’t need more than 25-28 MPH top speed, and gear two will suffice for most people, especially in the bike lanes. For street and traffic, gear three will help you keep up with cars if needed.

• Gear 1: 13-15 MPH top speed
• Gear 2: 29-30 MPH top speed
• Gear 3: +30 MPH and above top speed
• P9 is the torque and battery performance modes. P9:1 uses 50% power, P9:2 uses 70% power, P9:3 uses 100% power. P9:3 will drain the most charge, but will give you the most speed.
• P9: 1 – 28 MPH
• P9: 2 – 33MPH
• p9: 3 – 37MPH
• Eco Mode – Activating eco mode will allow you to enable the speed governor/gear. If you’re unsure if turbo mode is activated, lower the gear to 1. If you can’t go past 13/15 MPH, that means you’re in eco mode. If your speed has no limit, then you have turbo mode activated.
• Turbo Mode – Activating turbo mode will disable your speed governor. You will be able to ride at max speed/current based on your P settings. If your P9 setting is set to 1, you will not be able to use turbo mode.

Top Speed: After finding a slight stretch of a deserted road in Woodside, I could easily hit 45 MPH safely. Given that the weather is currently 32F and still have knobby tires, I will opt to do a top-speed run once the weather gets better, and also planning to purchase road tires or PMT slicks.

UPDATED TOP SPEED:

Today I was able to do a speed run with my friend Karem. He took his Thunder; I took out the Ultra 2 with the brand new speed damper installed.

By the time we arrived at an empty expressway by Rockaway Beach, I could hit +45 MPH easily. Today was pretty windy and cold; once I started tightening my body position and crouching my head down, the wind resistance and aerodynamics improved, and the GPS climbed to 55 MPH. By the time I reached this speed, the runway was getting shorter, and the roads became sketchier, so

My key takeaway is the Ultra 2 can get to 45 easy, and climb up to 55 MPH.

Once you get to 45, that’s when the adrenaline is dumped, and things get dicey. After hitting +55 MPH for the first time, I’m set on not trying this again until I get PMT’s tires and find a better stretch of runway. The Ultra 2’s torque and acceleration of 45 MPH are more than enough speed for me, especially since the pothole-riddled roads in New York City are not ideal for high-speed riding.

For the speed demons, I’m sure you can get past 55 and into the ’60s with the right conditions, warm weather, road tires, full charge, and a long stretch of runway. If you try this out, please be safe, know your roads, and wear protective gear; I had four close calls with bumps and giant potholes and could have easily wiped out at 50 MPH.

I’ll release a video on top speed in the near future, make sure to subscribe to my youtube channel in the meantime.

New Upgraded Damper (Ken Sonken Kit):

Battery Range

It’s still Winter in New York City, while under heavy wind and cold conditions, I could drain my battery down to 60% after a long hour of hard riding. I’ll release a video about the shortly expected range in warmer conditions soon.

The Ultra 2 features a 72V, 35AH, 2,520WH, 100A discharge MJ1 LG battery pack, rated up to 87 miles of range; for my fast riding style, the Dualtron Ultra 2’s range will likely be 35-45 high torque/speed miles. Their range performance will be lower than expected for riders carrying a heavy load, riding at full speed, up hills, uneven roads, or even in frigid temperatures.

It does depend on how you ride the Ultra; if you mix settings and hit the turbo button, you’ll get different results. Based on my usage, here’s my real-world range estimate based on high-speed and city riding:

• Max Performance Settings: +30 Miles (+45 MPH)
• Medium Performance Settings: +30-50 Miles (15 MPH – 30 MPH)
• Lowest Settings: +40-60 Miles (15 MPH – 30 MPH)

At 180 lbs and riding at slower cruising speeds in eco mode (low gear settings), I could see the battery pack outputting possibly 55-75 miles.

How’s the ride experience?

On Road:

Having owned a Dualtron Eagle Pro, learning how to ride the Ultra 2 was a slight learning curve. One of the first things you’ll notice is your newfound height. The Ultra 2 features 11″ tires; add that to the deck height and my riding boots; the Ultra 2 makes me stand at 7 feet tall! You’ll want to watch for tree branches and low ceilings when riding.

The knobby tires take some getting used to on-road; each tire outputs a unique buzzing sound as the tires rotate on the pavement. The wide tires and rod rubber suspension provide a softer and more comfortable ride as they absorb any uneven bumps in the road. The more expansive deck is a massive upgrade in my book, as it allows me to ride at a wider stance compared to the thinner Eagle Pro deck.

Off Road:

With its wide 11″ knobby tires and 6,640W of torque, the Ultra 2 shines off the road. On my first chance, I spun a few laps around an empty grass park; the Ultra 2 exceeded my expectations as I climbed the steep sections of the park and traversed across the field with little to no effort.

Braking:

Nutt Hydraulic brakes are some of the best brakes offered on performance electric scooters; they’re usually equipped on scooters that go past +45 MPH. Pushing past 35 MPH, I felt the Nutt Hydraulic brakes provide smooth and reliable stopping power. When comparing hydraulic to mechanical brakes, the bite is softer on the hands, reducing strain/fatigue on long-range rides.

Hydraulic brakes are also easier to maintain, as the brake pads self-adjust, unlike mechanical brakes that require regular cable adjustment. I’ve upgraded the Ultra to Magura MT7 for even more braking power.

Is the Dualtron Ultra 2 worth it?

With three 72V models for the 2021 riding season, MiniMotors offers three great options for your extreme-performance electric scooter needs. The Dualtron Ultra 2 is the lowest cost, but don’t let the price tag fool you; the Ultra 2 is packed with extreme performance and the latest innovative features, giving you the best value for your money.

If you’re looking for:

1. Insane torque and power
2. Long range, high discharge, 72V system
3. Tested and Proven Dualtron Chasis and Drivetrain
4. Reliable chassis with countless aftermarket and customization options
5. Best in class customer service and aftercare with MiniMotors USA

Then I would personally recommend the Dualtron Ultra 2 electric scooter to you, its absolutely worth its price tag.

What I love about the Ultra 2

• Powerful: Delivers on performance and range
• Features: Best lighting, handling, & braking
• Build Quality: 1st class design, high quality chassis and materials
• Comfort: Suspension and tires provide firm and comfortable ride

Now, if you are an absolute beginner or need to carry this 88 lbs scooter up a flight of stairs, I would consider different scooters.

Things to consider:

• Powerful: This scooter is extremely powerful, not the best scooter for beginners to learn how to ride. I recommend learning on a Dualtron Mini or Eagle Pro.
• Heavy: This scooter is not easy to carry, and can be large if you live in a small space. It’s one thing to lift the scooter, but another thing to carry it up a flight of stairs.
• Tires: Knobby tires are great for off road, not the best for high speed. Road tires are best for going speeds past 40 MPH.
• Damper: Will Need a steering damper for riding at high speeds (+40 MPH)
• Expensive: $4,000 is a big investment, MiniMotors USA offers high performance scooters at lower price tags, see list below.
