Fast Answer for Busy Riders β‘ (TL;DR)
The Teverun Tetra edges out the OKAI Panther ES800 overall - not because it's perfect, but because its monster battery, insane stability and off-road capability make it feel like a more extreme, more specialised machine for riders who actually want that. The Panther ES800 is the more civilised choice: better as a fast urban bruiser with "normal scooter" dynamics, sleeker design and far easier day-to-day living.
Pick the Tetra if you have a garage, space, budget, and a strong desire to surf dirt and gravel on four wheels for hours without seeing a charger. Choose the Panther if you mostly ride roads and paths, still want serious punch and comfort, but prefer something that looks and behaves like a scooter rather than a compact lunar rover.
Both are niche, both are heavy, and neither is truly practical for everyday commuters - but if you're still intrigued, keep reading; the differences on the road are bigger than the spec sheets suggest.
Two very different interpretations of "big, fast, overbuilt scooter" - that's the OKAI Panther ES800 and the Teverun Tetra in a nutshell. One's a hulking, premium-feeling two-wheeler from a brand that cut its teeth building rental tanks; the other is a four-wheeled science experiment that decided to become a production vehicle.
I've spent a ridiculous amount of time on both: hammering the Panther through broken city streets and fire roads, and muscling the Tetra over gravel, roots and the occasional unsuspecting molehill. They're both impressive, both flawed, and both over the top in their own ways.
If you're trying to decide between them, you're not choosing between "good and bad"; you're choosing between "wild and weirder". Let's unpack where each one actually makes sense - and where the romance ends the first time you face a staircase.
Who Are These For, and Why Compare Them?
Price-wise, these sit in very different leagues: the Panther ES800 lives in the upper mid-range performance bracket, while the Tetra strolls into the premium hyperscooter territory and orders the tasting menu. Yet people cross-shop them because they scratch the same itch: high power, big batteries, off-road capability and "car-replacement" potential for short to medium distances.
Both accept heavier riders, both promise serious hill-climbing, and both are way beyond what any sane person needs for a simple commute. The Panther is the "fast SUV scooter" - still recognisably a scooter, just more muscular. The Tetra is the "stand-up ATV" - four wheels, enormous battery, and a footprint that makes bike lanes nervous.
If you want a portable, multi-modal city tool, neither is for you. If you want something you park like a small motorbike and ride for fun, errands and weekend adventures, then the comparison suddenly makes sense.
Design & Build Quality
In the flesh, the Panther feels like OKAI took all its rental-scooter experience and finally let the designers off the leash. The unibody-style frame looks sculpted rather than bolted together, the cabling is tucked away, and that stem-integrated touchscreen gives off proper automotive vibes. It's the kind of scooter you can park in front of a fancy cafΓ© without feeling like you dragged in half a bike shop.
The Tetra, by contrast, looks like a robotics project that grew up and got a gym membership. Everything below deck is exposed engineering: linkages, arms, springs, multiple brake calipers. The forged frame feels brutally solid, but there's no pretending this is sleek. It's industrial and unapologetic. You don't so much "own" it as accept stewardship of a small machine park.
In the hands, the Panther's controls and levers feel more "finished". You notice the tidy cockpit, the stiff stem latch, the clean deck. With the Tetra, your first impression is, "that's a lot of moving parts I'll eventually have to tighten." Fit and finish are good, but the sheer mechanical complexity means more potential for rattles and squeaks over time.
Design philosophy in one line: Panther aims to be a refined, integrated product; Tetra is a functional exoskeleton built around the idea that more wheels and more metal solve most problems.
Ride Comfort & Handling
The Panther's comfort formula is simple and effective: very large pneumatic tyres plus proper suspension at both ends, on a long, wide deck. On broken city asphalt, it glides more than it should for something this heavy. Potholes you'd normally dodge become "suggestions" rather than threats, and the tall wheels in particular give a calm, planted feel in fast corners.
The suspension is set up on the firmer side of plush - it doesn't wallow, but it takes the sting out of curbs, cobblestones and trail chatter. On a 20-30 km mixed ride my legs and knees stayed surprisingly fresh, and the wide bars give decent leverage for quick corrections without feeling twitchy.
The Tetra is a different animal. Comfort in a straight line is superb: the independent suspension and larger tyres swallow ugly terrain so completely that you often see bumps you simply don't feel. On gravel and forest tracks, it feels almost comically unbothered - you're standing tall on a floating platform while each wheel negotiates its own relationship with reality.
But handling? That's where the cost of all that stability appears. Tight turns require real muscle; low-speed manoeuvres can feel like coaxing a supermarket trolley full of lead down a narrow aisle. On twisty paths you'll notice your arms getting a workout long before your legs do. It's stable and predictable, just not agile.
Sum-up: if you like the idea of carving, weaving and occasionally riding "sporty", the Panther behaves like a big, serious scooter. The Tetra behaves like a small utility vehicle - brilliant for ploughing through rough stuff, less lovable in tight urban choreography.
Performance
The Panther's dual motors deliver exactly the kind of punch you expect when you see its size. From a standstill, in the higher power modes, it surges forward with enough enthusiasm to make new riders instinctively lean back - which, on this scooter, is the wrong response. Once you get used to it, the acceleration is addictive but manageable. It pulls strongly up steep city streets and doesn't lose its nerve halfway up a nasty hill.
Top-speed-wise, it will go deep into "this should probably be registered as something" territory when derestricted, but its real party trick is how composed it feels approaching those speeds. The long wheelbase, big wheels and solid stem make it feel more like a compact e-motorbike than a gadget. Braking is similarly confidence-inspiring: the hydraulic system bites hard without drama, and you can modulate with one or two fingers even on downhill panic stops.
The Tetra, especially in the quad-motor configuration, is less about outright speed and more about unstoppable thrust. Off the line it doesn't just accelerate; it drags you forward like you hooked a tow rope to a tractor. On steep off-road climbs where most scooters are already giving up, the Tetra is just getting interested. It happily crawls up surfaces where walking would be the more sensible option.
Because its top speed is a notch lower, you don't get that same "oh dear, this is a lot of wind and consequence" feeling as on some hyperscooters. Instead, the drama comes from torque and traction. On loose surfaces you can feel all four wheels nibbling for grip, and the electronic braking plus four-disc setup hauls the mass down from speed with convincing authority - provided you respect that you're stopping the weight of a small motorcycle.
On paved roads, the Panther feels livelier and more natural to hustle. Off-road and on nasty climbs, the Tetra is the one that just keeps going when common sense says turn around.
Battery & Range
The Panther's battery is solidly sized for its class. For brisk city riding with plenty of full-throttle spurts and a few hills, you're realistically looking at an afternoon's worth of fun or a couple of days of commuting before you start eyeing the charger. Ride like a saint in eco modes and it will go pleasantly far, but nobody buys this thing to trundle along at pedestrian speeds.
One of its big practical wins is the swappable pack: you can leave the mud-spattered chassis in the garage and just carry the battery inside. For range junkies, a spare pack in the boot effectively doubles your day. Charging is also reasonably quick; topping up over lunch or during a workday is actually feasible.
The Tetra is in an entirely different league. Its battery is so oversized that it makes most other scooters feel like they're running on AA cells. Even ridden hard, you can burn through hours of mixed terrain before the gauge gets low enough to induce anxiety. Treat the throttle with some respect and that range stretches into genuinely long-distance territory - easily more than what most riders will tolerate standing up.
The flip side: refilling that enormous tank takes time. Charging is an overnight affair, not a quick splash-and-dash. You plan your rides the way you would with a small electric motorbike, not a toy scooter.
If you're a casual rider doing a handful of kilometres a day, both are overkill; you'll charge once in a while and that's that. If you want all-day excursions without thinking about sockets, the Tetra is the one that makes range anxiety feel like an old myth.
Portability & Practicality
Let's be blunt: neither of these should ever see the inside of a bus. The Panther is brutally heavy for a scooter, but at least it's shaped like something you can wrestle. The folding mechanism is solid and reassuring rather than elegant, and once folded it will just about fit into the boot of a typical car - as long as you're okay with lifting a large bag of concrete shaped like a scooter.
Carrying it up a full flight of stairs is technically possible, but you'll only volunteer to do it once. After that, you'll start planning your life around ramps, lifts and ground-floor storage. As a "ride from garage to destination, park outside" machine, though, it works quite well. It doesn't feel outrageously wide, so squeezing through barriers and doorways is still doable.
The Tetra laughs at the idea of portability. Even the lighter dual-motor version is a chore to move when you're not standing on it, and the full quad-motor variant is in "two people and a ramp" territory. Folding helps for transport in vans or large SUVs, but the footprint remains big and the width means standard doors are suddenly an event rather than a detail.
For daily life, the Panther is just about tolerable as a heavy personal vehicle; the Tetra is realistically a "garage toy" or utility platform. If your journey involves more than a couple of steps or any kind of public transport, the Panther is already borderline, and the Tetra is an immediate no.
Safety
Both machines take safety more seriously than the average scooter, but in different ways.
The Panther focuses on classic two-wheeler safety: excellent hydraulic brakes, big tyres for grip and stability, and a frame that doesn't flex alarmingly at speed. The large front light actually lets you see the road, not just pretend, and the integrated indicators and RGB strips boost your conspicuity in traffic. The tall wheels in particular pay off when you hit unexpected potholes or curbs; they're much less likely to grab and punt you off.
The Tetra's core safety proposition is: "what if you just didn't fall over?" Four contact patches mean low-speed slips on gravel or wet leaves become shrugs instead of crashes. For riders with balance issues or bad memories of front-wheel washouts, that alone can be life-changing. Add four-wheel hydraulic braking and aggressive tyres, and you get a sense of invulnerability - which is both its best feature and a slight concern if it makes you overconfident.
Lighting on the Tetra is stronger still, with that huge headlight and lavish perimeter illumination. The main downside is the low-mounted indicators and the sheer bulk of the machine; drivers see you, but they don't always understand what you're going to do next, and tight manoeuvres in traffic require planning.
On balance: if you're comfortable on two wheels and respect the power, the Panther feels very secure. If your priority is "I really, really don't want to fall at low speed again", the Tetra's four-wheeled platform is hard to beat.

Price & Value
The Panther sits in a bracket where expectations are high, but it doesn't have to be perfect to make sense. For the money, you get proper dual motors, a respectable battery, brand-name brakes, decent water resistance, and a design that looks more refined than many similarly priced "wire-and-tube" competitors. You can certainly find more outrageous specs for less, but usually with compromises in polish, braking hardware or brand backing.
The Tetra, on the other hand, is firmly in "serious hobby" pricing. At that level you start comparing it not just to other scooters, but to small motorbikes, ATVs and high-end e-bikes. As a pure commuting tool, the value proposition is weak; as a unique off-road-capable, four-wheeled electric platform with a battery the size of a small power station, it's easier to justify - if you're actually going to use what you're paying for.
Viewed coldly, the Panther is the more rational purchase for most performance-minded riders. The Tetra is only "good value" if you specifically want its rare mix of stability, range and off-road utility; otherwise you're paying a steep premium for capability you'll never tap.
Service & Parts Availability
OKAI's background in fleet manufacturing means they're not new to logistics. Parts supply and warranty handling in Europe tend to be more structured than with many no-name performance brands. That doesn't mean everything is perfect - you're still at the mercy of distributors - but panels, brakes and batteries aren't unicorns.
Teverun, as a younger brand, leans more on regional dealers and enthusiast-focused shops. Support quality varies by country, but in active markets, parts are reasonably obtainable and the community has already built up a decent knowledge base on maintenance and upgrades. The catch is complexity: four brakes, up to four motors, and intricate suspension arms mean more that can wear and more that you or your shop must understand.
If you like simple ownership, the Panther's more conventional architecture and big-brand heritage are comforting. The Tetra can be kept in good shape, but you need either a cooperative dealer or a willingness to get intimate with hex keys and threadlocker.
Portability & Practicality
(Focused recap, because with these two it matters a lot.)
The Panther is large, but you can still just about live with it in a city flat with a lift, and it behaves sensibly in bike racks, garages and normal parking spots. Folding is meaningful: it shortens the package enough for many car boots, and it's narrow enough to wheel through standard doors without a comedy routine.
The Tetra simply doesn't pretend to be practical in urban life. It's a "park in the garage, roll out when it's time to play or work the property" kind of machine. If you need to combine your ride with public transport, stairs, narrow corridors or tiny lifts, it fails the test immediately.
Safety
(Expanded recap.)
On the Panther, safety is strongly tied to the feeling of control. The braking system is predictable and strong, the chassis doesn't wobble at speed, and the lighting makes you stand out in traffic. It still demands decent rider skill - this is no beginner scooter - but it rewards smooth inputs and good gear.
The Tetra offers a different type of safety: it's hard to fall off by accident. For riders who've already had one painful crash, that alone can be worth the trade-offs. But don't confuse planted stance with invincibility: the mass and speed involved mean you absolutely need to respect braking distances and cornering limits. When things go wrong, they go wrong with a lot of momentum.

Final Verdict - Which Should You Choose?
These two don't compete in the usual sense; they just happen to appeal to the same kind of rider who looks at a "normal" scooter and thinks, "cute, but what else you got?" Still, forced to choose one as an overall winner, the Tetra nudges ahead - not because it's nicer to live with (it absolutely isn't), but because its combination of colossal range, all-surface stability and silly torque gives it a unique identity that the Panther doesn't quite match.
If you have space to store it, no stairs in your life, and a genuine plan to spend long hours on trails, rural roads or large properties, the Tetra delivers an experience closer to a stand-up ATV than a scooter. It's ridiculous, but it's coherently ridiculous.
For most riders, though, the Panther will make more sense. It's still heavy and overbuilt, but it's easier to manoeuvre, more elegant, and less of a maintenance project. As a fast, comfortable, solid-feeling road-focused scooter that can dabble in light off-road, it's the more balanced machine - just don't expect miracles if you treat it like a downhill bike substitute.
So: if your heart wants a four-wheeled land surfer and your life logistics can keep up, the Tetra is the wild choice that actually delivers. If your brain occasionally still gets a vote, the Panther is the one you can ride hard without needing a forklift and a workshop on standby.

Overall Winner Declaration
In the Numbers Freaks Corner, the OKAI Panther ES800 scores 5 points against the TEVERUN TETRA's 5. In the Author's Category Battle, the OKAI Panther ES800 gets 24 β versus 17 β for TEVERUN TETRA.
Totals: OKAI Panther ES800 scores 29, TEVERUN TETRA scores 22.
Based on the scoring, the OKAI Panther ES800 is our overall winner. Between these two, the Tetra is the machine that leaves the stronger emotional imprint: it feels outrageous, overbuilt and oddly liberating, like you've smuggled an ATV into the bike lane and gotten away with it. The Panther may not be as dramatic, but it's the one you're more likely to ride often - it behaves like a grown-up scooter, feels solid and composed, and doesn't demand you reorganise your life around its bulk. If you live where its strengths matter and you actually want to play in the dirt all day, the Tetra is the crazier, more memorable companion. If you just want a fast, comfortable, confidence-inspiring scooter that still fits into something resembling a normal routine, the Panther is the quieter, more sensible choice - and for many riders, that will ultimately make it the better partner.
That's our verdict when we try to stay objective β but hey, riding is mostly about emotions anyway, so pick the one that will make you look forward to your commute every single day.
