About
If you have been following the electric scooter scene for any length of time, you likely know OKAI as the silent giant behind the scenes. For years, they were the manufacturing powerhouse building those white-and-lime-green rental tanks you see scattered across city sidewalks globally. Recently, however, they have pivoted aggressively into the consumer market, and the OKAI NEON Ultra ES40 represents their most serious attempt yet to capture the heart of the dedicated urban commuter. It is the "big brother" in the Neon lineup, stepping up from the Lite and Pro models to offer something that feels less like a toy and more like a legitimate vehicle.
The philosophy behind the NEON Ultra ES40 is clear: it aims to bring the legendary durability of a shared scooter and marry it with the comfort and aesthetics demanded by private owners. While many scooters in the sub-1 000 EUR category force you to choose between a smooth ride and a portable frame, or between speed and range, the Ultra tries to strike a "goldilocks" balance. It is positioned directly to fight against industry heavyweights like the Segway Ninebot Max G2, offering a robust chassis that doesn't shy away from potholes.
What makes this machine special is its attention to the rider's experience beyond just getting from A to B. It features the distinct "Cyberpunk" aesthetic that the Neon line is famous for, but backs it up with a 48V system and genuine dual suspension. It is designed for the rider who is tired of rattling their teeth on cobblestones and wants a machine that feels substantial, planted, and capable of handling the unpredictability of city streets without needing a mechanic on speed dial.
Safety
When we talk about safety on an electric scooter, we have to start with braking, because going fast is optional, but stopping is mandatory. The NEON Ultra ES40 employs a dual braking system that combines a front drum brake with a rear electronic regenerative brake. For the uninitiated, drum brakes are fantastic for commuters because they are virtually maintenance-free. Unlike disc brakes, which can get bent or require frequent pad adjustments, the drum brake is sealed against the elements. In my testing and according to community feedback, the stopping power is reliable, with a braking distance of less than 10 meters. However, riders should be aware that the electronic rear brake is tuned quite aggressively; it kicks in with a strong "tug" that can surprise you if you aren't ready for it, though you eventually learn to feather it for energy recovery.
Visibility is where the OKAI NEON Ultra ES40 absolutely shines-literally. Safety isn't just about helmets; it's about being seen by that distracted driver turning left. This scooter features customizable LED lighting that runs along the stem and the deck. Through the app, you can set these to "breathing" modes or solid colors, effectively turning you into a moving light show at night. Combined with a bright, high-mounted headlight and an integrated taillight that flashes when braking, the scooter ensures you have a commanding visual presence on the road.
Stability is the final pillar of safety here. The scooter rides on 10-inch tubeless pneumatic tires. I cannot stress enough how much safer tubeless tires are compared to solid tires or tube-filled ones. They provide a larger contact patch for better grip during cornering and are far less prone to "pinch flats" when you accidentally hit a curb. The rubber compound OKAI uses is grippy, providing confidence even when the tarmac is slightly damp. Furthermore, the frame geometry is long enough to prevent that terrifying "over-the-handlebars" feeling during hard braking.
Performance
Under the deck, the NEON Ultra ES40 packs a brushless rear hub motor with a nominal power of 500 W, but don't let that modest number fool you. It peaks at a robust 1 000 W. In the world of electric mobility, peak power is what gets you off the line and up the hills. Riders report that the acceleration is zippy and responsive, with a distinct "kick" in Sport mode that makes weaving through traffic genuinely fun. It handles inclines of up to 25 degrees (approx. 46%) surprisingly well for a single-motor vehicle, maintaining momentum where lesser 350 W scooters would stall out and force you to walk of shame.
The top speed is capped at roughly 38 km/h (24 mph), which is the sweet spot for urban commuting. While speed demons might crave 50 km/h or more, 38 km/h is plenty fast for bike lanes and keeping up with city traffic flow. At this speed, the 48V system ensures the power delivery remains consistent. Unlike 36V scooters that start to feel sluggish once the battery drops below 50%, the higher voltage of the ES40 keeps the motor spinning happily even as you drain the "tank."
Community feedback regarding performance is generally glowing, with one caveat: the throttle curve. Some users note that the transition from zero to moving is smooth, but the engagement of the cruise control or the sudden bite of the regenerative braking can interrupt the flow. However, regarding raw power, it punches slightly above its weight class. It is not a racing scooter, but it is certainly a "get to work without sweating" scooter, capable of overtaking cyclists and rental scooters with ease.
Design
The design of the NEON Ultra ES40 is best described as "sleek industrial." OKAI has moved away from the utilitarian, exposed-wire look of early e-scooters and embraced a clean, integrated aesthetic. The cables are routed internally, which not only looks fantastic but prevents snagging. The standout feature is, of course, the vertical LED strip on the stem and the under-deck lighting. It gives the scooter a futuristic vibe that stands out in a sea of grey and black aluminum. The matte finish feels premium to the touch, and the materials used-mostly aviation-grade aluminum-exude a sense of solidity.
The folding mechanism is a critical aspect of design for any commuter, and OKAI has implemented a secure, easy-to-use latch. It folds down into a relatively compact package, though the handlebars do not fold in, which is a minor annoyance if you are trying to slide it under a narrow desk or into a crowded trunk. The deck itself is covered in a high-quality, grippy rubber mat with a geometric pattern that is easy to clean-a huge improvement over the sandpaper grip tape that gets dirty and peels off on other brands.
One design choice that draws mixed reviews is the display. It is a beautifully integrated circular screen that looks like a smartwatch face, providing crisp information about speed, battery, and mode. It looks incredibly high-tech. However, in direct, harsh sunlight, the glossy finish can sometimes suffer from glare. Despite this, the overall build quality feels "tank-like," a direct inheritance from OKAI's commercial roots. There is zero stem wobble out of the box, a rarity in this price bracket.
Comfort
If there is one reason to buy the NEON Ultra ES40 over its cheaper siblings, it is the suspension. This scooter features a dual suspension setup: a hydraulic shock absorber in the front and an adjustable spring shock absorber in the rear. This is a game-changer. Most entry-level scooters rely solely on pneumatic tires to dampen vibrations, but the ES40 actively absorbs bumps. The front hydraulic suspension handles high-frequency vibrations (like cobblestones) beautifully, while the rear spring takes the edge off larger hits (like potholes or dropping off a curb).
The "Adjustable" part of the rear suspension is particularly noteworthy. It allows riders of different weights to tune the stiffness. A 60 kg rider needs a very different bounce than a 100 kg rider, and being able to tighten or loosen that spring means you can dial in the ride to be plush or firm. Combined with the 10-inch pneumatic tires, the ride quality is described by owners as "floating." You stop scanning the road for every tiny crack and just enjoy the glide.
Ergonomics also play a huge role in comfort. The deck is spacious and long, allowing for a comfortable stance where you can switch your feet position during long rides. The handlebars are wide enough to provide good leverage and control, which reduces shoulder fatigue. Even the throttle thumb paddle is designed with a soft-touch material that feels good during a 45-minute commute. It is a scooter designed for adults who value their joints.
Range
Let's have an honest conversation about range, as this is where marketing often clashes with reality. The manufacturer claims a maximum operating range of 69.6 km (43.5 miles) on a single charge, thanks to its substantial 48V 14.7Ah (approx. 720Wh) battery. However, as any experienced enthusiast knows, "Max Range" is usually tested with a light rider, on a flat indoor track, at a slow speed, with a tailwind. It is a theoretical maximum, not a daily promise.
In the real world, based on numerous user reviews and independent tests, you should expect a realistic range of closer to 40 km to 45 km (25 to 28 miles) if you are riding in the top speed mode and tackling mixed terrain. If you ride conservatively in "Eco" mode, you might stretch that to 55 km. While this falls short of the 70 km claim, it is still an excellent range for this price point. It means you can commute 15 km to work and 15 km back without even bringing your charger, which is the true benchmark for a reliable commuter.
Charging time is approximately 6 to 7 hours from empty to full. This is standard for a battery of this capacity. The charger is relatively compact, so carrying it in a backpack isn't a burden if you plan a massive cross-town excursion. The battery management system (BMS) is sophisticated, protecting against overcharging and overheating, which adds to the long-term peace of mind regarding the battery's lifespan.
Use and Practicality
Living with the NEON Ultra ES40 is mostly a joy, but there is one literal heavy factor to consider: the weight. At roughly 23 kg (approx. 50 lbs), this is not a lightweight scooter. If you live in a fourth-floor walk-up apartment without an elevator, this scooter is likely not for you unless you want a free gym workout every day. The weight is the trade-off for the large battery, robust motor, and dual suspension system. It feels planted on the road, but heavy in the hand.
However, for those with elevators or garages, the practicality is high. The folding mechanism is quick, taking about 3 seconds to collapse the stem. Once folded, it fits into the trunk of a standard sedan, although it might be a tight squeeze in a compact car. The scooter also features NFC unlocking. You get a cool little card (and can use your phone) to unlock the scooter, which adds a layer of security and makes you feel like you are starting a spaceship rather than a kick scooter.
The OKAI app adds another layer of utility. It allows you to customize the drive modes, check detailed battery stats, and even lock the motor electronically. While electronic locks shouldn't replace a sturdy U-lock, they are great for quick stops at a coffee shop. The kickstand is sturdy and well-placed, supporting the heavy frame without tipping over on slightly uneven ground.
General Assessment
Overall, the OKAI NEON Ultra ES40 is a triumphant entry into the mid-range performance commuter market. It successfully sheds the "rental" stigma while keeping the "rental" durability. The community consensus is overwhelmingly positive, with riders frequently praising the smoothness of the ride and the sheer build quality. It feels like a solid block of engineering rather than a collection of parts bolted together.
Most complaints are minor and center around the weight or the optimistic range marketing-both of which are industry-wide issues rather than specific flaws of this model. The "jerky" regenerative brake is a common talking point, but many users report getting used to it after a week of riding. The lighting customization is a crowd favorite, adding a fun factor that many utilitarian scooters lack.
If you are looking for a scooter that can handle the daily grind, survive the occasional rain shower (thanks to its IPX5 rating), and look good doing it, the ES40 is a top-tier contender. It bridges the gap between the entry-level "toy" scooters and the terrifying "hyper-scooters," sitting comfortably in the zone of "reliable, fast, and fun transport."
Who Is This Scooter For?
The NEON Ultra ES40 is ideal for the serious urban commuter. If you have a commute of 10-30 km round trip and want to do it faster than a car in rush hour, this is your machine. It is perfect for riders who have to deal with less-than-perfect roads; the suspension will save your knees and back from the punishment of potholes and cracks.
It is also an excellent choice for heavier riders. With a max load capacity of roughly 120 kg (265 lbs) and a powerful 48V motor, it doesn't struggle under load the way 350W scooters do. The adjustable rear suspension is a godsend here, allowing heavier riders to stiffen the spring to prevent bottoming out.
Conversely, this scooter is not for the multi-modal commuter who needs to carry their scooter onto a bus or train regularly. The 23 kg weight makes it cumbersome to lug around crowded platforms or up long flights of stairs. It is also not for the speed freak who wants to race cars at 60 km/h; it is speed-capped for safety and legal compliance in many regions.
Community Feedback - Pros

- High Voltage System: The 48V architecture provides sustained power even as the battery drains.
- NFC Security: The keycard unlock feature is seen as a premium, convenient touch.
- Good Water Resistance: The IPX5 rating gives riders confidence in light rain and puddles.
The most consistently praised aspect of the ES40 is undoubtedly the ride comfort. Riders moving up from solid-tire scooters or non-suspended models describe the experience as "night and day." The ability to glide over manhole covers and cracks without jarring your entire skeleton is a luxury that, once experienced, is hard to give up. The lighting system also gets frequent mentions, not just as a gimmick, but as a genuine safety feature that makes riders feel visible to cars.
Community Feedback - Cons
- Heavy to Carry: At 23 kg, it is significantly heavier than "light" scooters, making stairs a challenge.
- Aggressive Regen Brake: Many users find the electronic braking kicks in too hard, causing a jerky motion.
- Optimistic Range Specs: Real-world range is about 60-65% of the claimed 70 km.
- No Pre-slimed Tires: Unlike some competitors, the tires don't come with self-healing sealant inside.
- Glossy Display Glare: The screen can be hard to read in direct overhead sunlight.
- Handlebars Don't Fold: This limits how compact the scooter can get for storage in tight spaces.
- App Connectivity Issues: A few users reported occasional Bluetooth connection drops with the app.
- Kickstand Length: Some riders feel the kickstand is slightly too long, keeping the scooter too upright.
While the scooter is well-loved, the weight is the most common grievance. It sits in an awkward spot where it's too heavy to carry easily but not heavy enough to be a "performance beast." The regenerative braking curve is another frequent topic of discussion in forums; users wish for an app update to adjust the sensitivity of the regen brake, as the current setting feels like hitting a wall for some. However, none of these issues are generally considered deal-breakers, just things to be aware of.
Value for Money
At a price point of around 848 EUR, the OKAI NEON Ultra ES40 presents a compelling value proposition. It sits in a competitive bracket, often compared directly to the Segway Ninebot Max G2. While the Segway might have slightly better brand recognition in the consumer space, the OKAI counters with a more striking design, customizable aesthetics, and a ride quality that many argue is superior due to the hydraulic front end.
When you break down what you are getting-a 48V system (versus the 36V often found in cheaper models), genuine dual suspension, app integration, and a chassis built by a commercial fleet manufacturer-the price feels justified. You are paying for longevity. This isn't a disposable toy that will fall apart in six months; it's an investment in a vehicle that should last for years of daily use.
Is it a bargain? Perhaps not in the "cheap" sense, but it is fair. You get exactly what you pay for: a premium, reliable, and comfortable commuter. If you can find it on sale, which happens occasionally, it becomes an absolute steal. Compared to high-end performance scooters that cost 2 000 EUR+, it offers 80% of the comfort and utility for less than half the price.
About the Brand
OKAI has a unique history in the electric mobility world. While brands like Xiaomi and Segway captured the early consumer market, OKAI was busy building the fleets for the world's largest scooter sharing companies. This gave them a massive dataset on how scooters break, where they fail, and how to build them to survive abuse. This "commercial DNA" is evident in every consumer product they launch. They are known for over-engineering their frames and focusing on low-maintenance components.
In recent years, OKAI has worked hard to build a consumer-friendly image, improving their customer support and app interface. The community generally regards them as a trustworthy manufacturer, not a "fly-by-night" drop-shipper. Parts availability is generally good because many components are shared with their vast fleet of commercial vehicles. If you are interested in their engineering philosophy, it is worth checking out other scooters from this brand to see how they scale their technology from lightweight portables to heavy-duty cruisers.

Known Alternatives
The electric scooter market is crowded, and while the NEON Ultra ES40 is fantastic, it pays to shop around. One strong competitor is the MS ENERGY Mentor. This scooter often competes in a similar segment, offering robust performance and a focus on ride stability. Riders who prioritize a different aesthetic or perhaps a different local dealer network might find the MS Energy lineup appealing.
For those looking for something with a bit more "rugged" flair or perhaps different branding, the MS ENERGY Urban X series is another place to look. Additionally, if you are willing to spend a bit more for a brand synonymous with high-performance, the DUALTRON Dolphin is worth a look. Dualtron is known for insane power, and while the Dolphin is their entry-level model, it carries that performance pedigree.
Finally, for those who want a slightly different suspension feel or a more compact fold, the VSETT Vsett8 is a legendary commuter favorite. It has solid tires (no flats!) and a very unique suspension feel, though the ride is harder than the OKAI. Alternatively, the MUKUTA Mukuta 10 Lite offers a more aggressive, sporty design that appeals to those who find the OKAI a bit too "clean" looking.
