Fast Answer for Busy Riders ⚡ (TL;DR)
If you want the more rounded, confidence-inspiring package, the OKAI Panther ES800 edges out as the better overall scooter: it brakes harder, rolls more smoothly on rough ground, and feels more like a finished vehicle than a fast project. The Apollo Phantom 20 suits riders who prioritise road-focused speed, strong water protection and clever regen braking over off-road toughness and hydraulic stoppers. Choose the Panther if your rides mix bad tarmac, gravel and the occasional forest path; choose the Phantom if you're mostly on asphalt, like advanced regen control and don't mind paying extra for tech polish and weather sealing. Both are big, heavy "keep it on the ground floor" machines, so your storage situation should probably have the final word.
Stick around for the full comparison before you drop a couple of thousand Euro on something you may have to drag up a staircase.
There's a point in e-scooter ownership where flimsy commuter toys stop making sense and you start eyeing the big stuff - the kind of scooters that don't flinch at potholes, laugh at hills, and weigh about as much as a small asteroid. That's exactly where the Apollo Phantom 20 and the OKAI Panther ES800 live.
Both promise serious power, long-ish range and "proper vehicle" build. On paper, they're close enough to make your head spin; in reality, they feel like two very different interpretations of the same idea. The Phantom leans towards high-speed road prowess, techy features and heavy weather use. The Panther goes for bomb-proof off-road stability, big wheels and a surprisingly grown-up design with less drama and more composure.
If you're torn between them, you're exactly the kind of rider these scooters court. Let's dig into how they actually behave once the spec sheet ends and the asphalt (or gravel) begins.
Who Are These For, and Why Compare Them?
Both scooters sit firmly in the "serious money, serious weight" bracket. They're not for casual rental refugees who just discovered the throttle last week; they're for riders ready to replace quite a few car trips and want something that doesn't feel disposable after one winter.
The Apollo Phantom 20 positions itself as a high-performance street scooter: fast, tech-forward, with big suspension and enough speed to keep up with city traffic when the road opens. Think aggressive commuting, long cross-town runs and suburban-to-centre trips on mostly paved roads.
The OKAI Panther ES800 sits in a very similar power and price territory but with a more off-road-capable stance. Huge tyres, hydraulic brakes, unibody frame - it's clearly designed for riders who see broken pavement and dirt tracks as an invitation rather than a warning.
They cost in the same broad ballpark, they weigh roughly the same, they target experienced riders, and they both claim to be your "big boy/girl scooter". That makes them natural rivals - and good candidates to show where your money really goes.
Design & Build Quality
In the flesh, these two don't feel like cousins; they feel like rivals from different design schools.
The Phantom 20 has that recognisably Apollo, angular, "future-industrial" vibe. Lots of edges, a serious-looking stem, exposed but tidy cabling, and that large hexagonal display that screams "I'm clever". The deck and frame feel stout and dense in the hand, more like a compact urban machine than an off-road rig. It's clearly built to look special next to the sea of generic black tubes, and to Apollo's credit, it does.
The Panther ES800, in contrast, looks like it rolled out of an automotive design studio. The unibody frame feels monolithic - fewer obvious welds, fewer visible bolts, and almost all the wiring hidden away. In your hands it feels less "assembled from components" and more "cast as one piece". The matte black finish and tasteful lighting make it look grown-up rather than shouty, and the integrated touchscreen in the stem is something you'd expect from a concept scooter, not a production one.
Side by side, the Apollo looks more traditionally "scooter-y" with tech add-ons; the OKAI looks more like a complete industrial product. Neither is badly built - far from it - but the Panther has the more mature, cohesive execution, while the Phantom leans on its distinctive styling and proprietary parts to stand out.
Ride Comfort & Handling
After several long days swapping between them, comfort is where their philosophies really diverge.
The Phantom 20 sits on big, wide pneumatic tyres and a quad-spring suspension at both ends. That combination gives you generous travel and a "hovering" feel over broken city tarmac. Expansion joints, small potholes, cobbles - the springs soak up a lot, and you can tune them a bit to your weight and preferences. On smoother bike lanes and decent roads, it's genuinely plush, bordering on floaty if you like a soft setup. The wide handlebars and spacious deck help you settle into a stable stance, especially when accelerating hard.
The catch? On really rough stuff - deep potholes, rutted gravel, roots - the Phantom still feels fundamentally like a heavy road scooter venturing out of its comfort zone. It copes, but it's not exactly in its element; you feel the hits more sharply through the chassis than the spring count would make you hope.
The Panther ES800 counters with fewer springs on paper but more composure in real life. The combination of chunky 12-inch tubeless tyres and proper fork-plus-rear shock suspension makes a huge difference. Those wheels just roll over things the Phantom tends to crash into. On bumpy bike paths and broken country lanes, the Panther feels less stressed: the steering stays calmer, and your knees don't have to work overtime.
Handling-wise, the Phantom changes direction a bit quicker and feels more alert, which keen riders will enjoy on twisty asphalt. The Panther, by contrast, is more planted and slightly slower to tip in - but that's exactly what you want when the surface is loose, wet, or otherwise sketchy. If your usual route includes gravel paths, patchy rural roads, or tram-track hell, the Panther simply copes better without making a drama out of it.
Performance
Both of these scooters are deep into "don't lend it to your inexperienced friend" territory. The question isn't whether they're quick - it's how they deliver that speed.
The Phantom 20 hits hard off the line. Dual motors and Apollo's aggressive modes mean that, in its spicier settings, it will happily rip you off the line faster than most cars are willing to accelerate in town. The mid-speed shove is strong enough to make overtakes feel trivial, and top speed is more than enough to get you into trouble with local laws if you're not on private roads. On open urban stretches, it feels like a fast street machine: eager, urgent and slightly egging you on.
The Panther ES800 isn't exactly shy either. It's a touch more modest at the very top end, but its party trick is torque. That strong low-end pull makes it feel extremely confident on steep climbs and off the line, even with a heavier rider. In the mid-range it doesn't have the same manic "oh, hello" surge the Phantom can give you in its wildest mode, but the power delivery is smoother and more measured. You still grin; you just don't feel like you've signed a waiver.
Braking is where the two really separate. The Phantom's mechanical discs, supported by its clever dedicated regen throttle, do a decent job. The regen lever on the left bar lets you scrub speed with surprising precision; once you get used to it, you can do most of your speed control that way, saving the physical brakes for proper emergency stops and very low-speed manoeuvres. It's smart, and it genuinely changes how you ride.
The Panther, though, comes with full hydraulic NUTT brakes. One finger on each lever, and you get firm, progressive bite that just keeps coming. From high speeds, the stopping power and feel are simply in a different league. Pair that with the big tyres and stable chassis, and you get braking performance that makes high-speed riding feel less like a gamble and more like a controlled activity.
Hill climbing? Both demolish slopes that would see rental scooters begging for mercy. The Phantom has no trouble punching up brutally steep urban climbs. The Panther feels similarly unstoppable, especially with its strong torque and big contact patches, which help when the hill is also dusty or wet. On clean, dry asphalt, it's broadly a draw; on sketchy surfaces, the Panther usually feels like the calmer, more sure-footed choice.
Battery & Range
On the battery side, the Phantom brings the bigger theoretical tank; the Panther brings a more flexible approach to fuelling it.
The Phantom 20 carries a noticeably larger battery pack. On paper, its "up to" range figure looks generous enough to impress your non-scooter friends. But once you ride it as intended - dual motors, proper speed, some hills - you'll land in the mid double-digit kilometre zone rather than chasing the marketing promise. It's still plenty for a long daily commute with detours, but you do feel the drain if you lean hard on its faster modes. Charging on the stock brick is very much an overnight affair; you plug it in, forget about it and hope you didn't bump the socket.
The Panther ES800 has a smaller battery on paper, and in similar "ride it like you stole it" conditions it will typically give you a bit less distance than the Phantom before you start thinking about your route home. The difference isn't night-and-day in real riding, but it's there if you push both equally hard.
Where the Panther fights back is flexibility. The deck houses a removable pack. That means you can bring just the battery upstairs, not the 40-plus-kg scooter, and you can carry a spare if you're into all-day adventures. Charging is also quicker, so even a long lunch break can give you a meaningful top-up.
Range anxiety? On the Phantom, with its bigger battery, I was generally more relaxed on long paved runs - as long as I wasn't going full lunatic everywhere. On the Panther, I found myself thinking a bit more about speed and mode selection on longer mixed-terrain days, unless I had a second battery waiting. Both will comfortably do a typical city round trip at sensible speeds; it's when you live at the "sport mode, always" end of the spectrum that the Phantom's extra capacity starts to matter.
Portability & Practicality
Let's be honest: neither of these scooters is "portable" unless you also consider a washing machine portable.
The Phantom 20 is brutally heavy. You can fold it and hook the bars into the rear, but that's mainly so you can shuffle it into a car boot or a corner, not because anyone enjoys carrying it. Lifting it into a higher boot or dragging it up stairs is, at best, a reluctant gym session. This is a ground-floor, garage or lift-building scooter. Multimodal commuters need not apply.
The Panther ES800 is only marginally lighter, which in this weight class doesn't really change your life. Its folding latch is chunky and secure; once folded, the footprint is reasonably compact for the class, but the sheer mass and bulk still make it a poor match for trains and third-floor flats. Realistically, you roll it in and out of a garage or lift-access flat, or you leave it parked in an underground car park next to the big bikes.
In everyday use, though, both work well as "door-to-door" vehicles. The Phantom's higher water-resistance rating makes it the better choice if your climate specialises in horizontal rain and you refuse to leave the scooter at home. The Panther's removable battery is more practical if your parking spot has no plug - you can leave the scooter in the bike room and only carry the pack. In practice, your building layout and access to power will sway this more than a kilogram here or there.
Safety
With scooters this fast and heavy, safety isn't a nice-to-have; it's the whole game.
The Phantom 20 scores well with its lighting and weather resilience. The high-mounted headlight actually lights up the road, not just a puddle a few metres ahead. Side and deck lighting plus indicators make you stand out far better than the usual "tiny LED on the stem" approach, and the strong water resistance rating means electronics are less likely to have a meltdown when your commute turns into a monsoon. The chassis and stem feel stout at speed; with the suspension sorted and tyres properly inflated, high-speed wobble isn't really a thing unless you force it.
However, in raw "oh no, that car just pulled out" moments, mechanical discs can only do so much, even with clever regen helping. They're decent, but you do need a firmer squeeze and slightly more anticipation than on a top-tier brake setup.
The Panther ES800 answers that with those NUTT hydraulic brakes and huge tyres. The combination of strong bite, great modulation and more rubber on the road means emergency braking feels dramatically more controlled. You can haul it down from silly speeds with less panic and less chance of locking everything up. The big headlight and integrated indicators keep you visible, and the chassis feels extremely solid when you're fully on the anchors.
Water protection is a little more conservative than the Phantom's, but still perfectly adequate for most real-world rain riding, provided you're not trying to fording rivers. Overall, if your main safety concern is stopping distance and stability at speed, the Panther has the edge. If your environment is regularly soaked and grim, the Phantom's stronger IP rating is reassuring.

Price & Value
Both machines live in that slightly uncomfortable price zone where you expect a lot - and you should.
The Phantom 20 asks noticeably more money. For the extra spend you get a larger battery, richer app and display experience, more advanced regen implementation, very good water resistance and a generally high level of polish around the cockpit and controls. You also pay a bit of a "brand tax" for Apollo's ecosystem and community, plus Europe-friendly support and spares.
The Panther ES800 undercuts it meaningfully while still offering dual motors, premium brakes, big tyres, a swappable battery and a very slick unibody design with integrated touchscreen. You sacrifice some battery capacity and the Apollo-style regen party tricks, but gain hydraulics, easier charging logistics and often a better-feeling chassis for the money.
From a cold value perspective, the Panther feels like the more sensible purchase: less outlay, still very capable, and you don't feel short-changed in build quality. The Phantom makes more sense if you particularly care about its larger battery, water protection and more elaborate electronics - and you're willing to pay for those specific strengths.
Service & Parts Availability
Apollo has worked hard on building a real ecosystem around its scooters. For the Phantom 20, that means decent parts availability, official content on maintenance and a network that, while not perfect, at least exists in a structured way in Europe and North America. Community knowledge is also strong - plenty of owners, plenty of guides, plenty of "I've already broken this, here's how to fix it" posts.
OKAI comes from the fleet world, which means they absolutely know how to build for durability and keep vehicles running. On the consumer side, they're still catching up in terms of community size compared with brands like Apollo or Dualtron, but their distribution and spares situation in Europe is improving, and the Panther is far from an obscure curiosity. Still, you're a bit more at the mercy of official channels for certain specific parts.
For self-tinkerers, the Phantom ecosystem is currently the slightly friendlier place to live. For people who just want a scooter that doesn't need constant fiddling, the Panther's "built like rental hardware" DNA is a quiet advantage.

Final Verdict - Which Should You Choose?
Both scooters are big, capable and overkill for most casual riders. So the real question is: what kind of overkill do you want?
If you mainly ride on roads and half-decent bike lanes, want a bit more outright speed and value rich electronics, the Apollo Phantom 20 makes sense. Its regen throttle is genuinely nice to live with, the big battery stretches aggressive city riding comfortably, and the weather protection means you don't have to treat every cloud like a personal threat. It feels like a fast, heavy street scooter with some thoughtful tech sprinkled on top.
If your routes include rougher tarmac, broken surfaces, gravel paths or you simply care more about stability, braking confidence and value, the OKAI Panther ES800 is the stronger package. It rides calmer at speed, the hydraulic brakes inspire more trust when things go sideways, and the removable battery plus quicker charging make day-to-day ownership less of a hassle. For most riders who aren't chasing every last kilometre per hour, the Panther's blend of security, comfort and pricing will just quietly make more sense.
In my book, the Panther walks away as the more complete "big scooter you can actually live with", while the Phantom will appeal to those who specifically want its extra speed, water resistance and regen cleverness - and are happy to pay and wrench a bit more for the privilege.
