Fast Answer for Busy Riders ⚡ (TL;DR)
If you care mainly about comfort and distance, the InMotion S1F walks away with this one. Its long-range battery, genuinely plush suspension and big-rider friendliness make it the stronger real-world commuter, especially for longer daily rides and heavier riders.
The Acer Predator Storm makes more sense if you want to spend less, keep weight slightly more manageable, and you like the "gaming" aesthetic plus turn indicators in a slimmer package. It's a competent mid-range scooter, just not a standout.
In short: S1F for serious commuting and range; Predator Storm for shorter urban hops on a tighter budget.
Stick around for the full breakdown - the differences get much clearer once we talk ride feel, hills and day-to-day living.
There is a certain déjà vu to reviewing modern mid-range scooters: single rear motor, decent battery, app connectivity, black paint, some marketing noise about "urban warriors". Both the Acer Predator Storm and InMotion S1F fit that script - but they approach it from very different angles.
The Predator Storm is Acer's attempt to turn its gaming pedigree into asphalt credibility: edgy looks, app, indicators, a "Predator" badge that screams more LAN party than bike lane. It's best for riders who want a slightly sportier commuter without emptying the savings account, and who are willing to accept some compromises for the price.
The InMotion S1F feels more like an overbuilt commuter appliance: long deck, long range, long wheelbase - the limo of single-motor scooters rather than a streetfighter. It's best for riders who care more about comfort and distance than bragging rights.
On paper they look like close cousins. On the road, they behave like they were raised in different households. Let's dig into where each one shines - and where the shine rubs off.
Who Are These For, and Why Compare Them?
Both scooters sit in the mid-tier commuter space: more serious and capable than rental clones, still far from the wild dual-motor beasts. They are priced apart, but not in different galaxies - the Predator Storm clearly the cheaper ticket, the S1F pushing into "I'm actually replacing my car/bus" territory.
They both target riders who:
- want a "proper" daily vehicle, not a toy
- need real-world range beyond a quick supermarket dash
- value some comfort on rough city tarmac
The reason to compare them is simple: if you are ready to move beyond entry-level scooters, both pop up as options. One says "save money, get decent power and features"; the other says "spend more now, forget about range and comfort issues later". Knowing which compromise fits you better is the whole game here.
Design & Build Quality
Pick them up and you immediately feel the difference in philosophy. The Predator Storm feels like a solid, straightforward commuter: aluminium frame, classic stem-into-deck fold, fairly clean cabling, and that angular "Predator" styling. It has a bit of gamer attitude, but under the skin it's a pretty conventional layout. No major rattles, tolerances are fine, but it doesn't exactly scream "heirloom piece".
The S1F feels more like a finished product from a dedicated mobility brand. The chassis is chunkier, the stem taller, and the whole scooter gives off "one big piece of metal" vibes. Cable routing is better hidden, the deck covering is a thick rubber mat rather than cheap grip tape, and the side lighting is integrated rather than tacked on. You pay for that extra polish in both money and kilos.
In the hands, the Acer feels lighter and a touch more nimble to manhandle, while the S1F feels denser and more serious. Neither is junk by any stretch, but the S1F does feel the more mature design - the Predator feels more like a first-gen effort from a PC brand (because it is).
Ride Comfort & Handling
This is where the gap opens up. The Predator Storm gives you air-filled tyres and a basic front spring. On mildly broken city streets it does an acceptable job: small cracks and expansion joints are muted, and your hands don't buzz to sleep. But push it onto rougher cobbles or broken pavement for more than a few kilometres and you start to feel where Acer drew the line on cost. The rear is unsuspended, so your knees and ankles do the damping.
The S1F, by contrast, feels like it was built by someone who actually commutes on bad roads. Dual shocks at the front, dual springs at the rear, plus tubeless pneumatic tyres - all tuned more for plushness than sportiness. On the same stretch of lumpy tram tracks where the Predator politely reminds you of every imperfection, the S1F just... flows. You still feel the road, but it's background noise, not punishment.
Handling-wise, the Predator is shorter and a bit more flickable at low speed. It weaves through pedestrians and bollards with less effort, and the slightly lower overall mass helps. The S1F has a longer wheelbase and a taller stem, so it feels more stable in a straight line and at speed, but less eager to dart between obstacles. Think hatchback versus estate car - both usable in town, one more agile, one more relaxed.
Performance
On paper, both scooters use similar-rated rear hub motors. On the road, they tune that power very differently.
The Predator Storm's acceleration is lively enough for its class. From a traffic light, you can leave rental scooters behind and slot into the flow without drama. It copes with typical city inclines reasonably well; on steeper hills you feel it working hard, but not completely giving up. Top speed sits in the "fast commuter" bracket - enough to feel brisk, not enough to be genuinely scary. The throttle response is fairly direct; beginners will want a gentler mode at first.
The S1F pulls with more authority, especially under heavier riders. InMotion squeezes the torque curve to favour hill-climbing and mid-range shove, so it feels stronger on climbs and when accelerating from cruising speed. Its maximum speed nudges above the Predator's, but more importantly it feels happier holding that pace without sagging as the battery empties. Power delivery is smoother, less "on/off", and with the longer wheelbase the whole package feels more planted when you're close to its limit.
Braking tells a similar story of priorities. Acer uses a front disc plus rear electronic brake. Stopping power is fine, and you can scrub speed quickly when needed, but you can occasionally feel the rear e-brake cutting in a bit abruptly if set strong. The S1F pairs a sealed front drum with strong regenerative braking at the rear. It lacks the hard mechanical "bite" of a sharp disc, but offers consistent, weather-resistant stopping with less tinkering - very "commuter first", slightly less "enthusiast pleasing".
Battery & Range
Both scooters promise generous range; only one really changes how you think about charging.
The Predator Storm's battery is big for its price class. In sensible riding - not crawling, not full-send all the time - you can realistically expect several commutes of moderate length before needing the charger. Aggressive riding or a heavier rider will pull that down, but it's still in the "comfortable daily commuter" zone rather than "hope I make it home". Range anxiety is reduced, not eliminated.
The S1F, on the other hand, is built for distance. Its battery pack is substantially larger and runs at a higher voltage, and in the real world that translates into rides that feel like they go on forever. Even riding briskly, it's common to get multiple long days between charges. For delivery riders or those doing cross-city trips, this is a big deal: you stop planning your route around sockets.
Charging is the flip side. The Predator, with its smaller pack, recharges overnight or during a workday without fuss. The S1F takes longer on a single charger, but offers dual charging ports to claw back time if you're willing to buy a second brick. In everyday commuting, I found the S1F's sheer range still more convenient - you simply plug in less often - but if your pattern is "short ride, charge, short ride, charge", Acer's smaller tank is easier to refill.
Portability & Practicality
Neither of these is a featherweight "last-mile" scooter. If you need to sprint up three flights of stairs every day, you picked the wrong category. That said, the differences still matter.
The Predator Storm lands a few kilos lighter than the S1F. You feel that every time you have to lift it into a boot or onto a train. The folded package is slightly shorter and a bit more compact, so it hides under desks and in small hallways more gracefully. The folding hinge is conventional but robust enough, and once you get the muscle memory it's a quick one-hand-and-foot operation.
The S1F is... substantial. Carrying it up more than one floor feels like penance for not doing leg day. The tall non-telescopic stem and non-folding bars mean that even folded it occupies a big rectangle of space. It will fit in most car boots, but not elegantly in small ones, and it's not the scooter you want fighting you in a crowded train aisle. On the flip side, that size buys you a huge, comfortable deck and tall, natural bar height - so if you mostly roll from door to door with lifts at both ends, the trade-off can be worth it.
Safety
On safety, both brands clearly did their homework - just with different accents.
The Predator Storm gives you a mechanical front disc, electronic rear brake, and a full spread of lights including built-in turn indicators. Those indicators are actually useful in busy city traffic; being able to signal without taking a hand off the bar is a genuine improvement. Water protection is solid enough that normal rain isn't a panic event, provided you're not actively trying to drown it.
The S1F goes further on the visibility front. The high-mounted headlight throws light where you actually look, the side LEDs make you stand out laterally, and the auto-activated turn signals triggered by lean or steering angle are clever and practical. You feel very "seen" at night. Braking is progressive and confidence-inspiring once you adapt to the regen-first feel. Add the long wheelbase and low-mounted battery, and the S1F feels more planted when emergency manoeuvres happen - swerving around a car door, for example, feels calmer on the longer, lower chassis.
Traction-wise, both run on tubeless pneumatic tyres, which is exactly what you want for grip and puncture resilience. The S1F's suspension gives it an edge on rough or wet surfaces - it keeps more rubber in better contact with the road when the ground gets messy.

Price & Value
The Predator Storm positions itself as the affordable "big battery, decent power" option. For its asking price you get a motor that's punchy enough, a battery that outclasses many similarly priced scooters, and bonus features like turn signals and app control. If budget is tight and your rides aren't epic marathons, the value proposition is respectable - you're not being ripped off, even if nothing here redefines the class.
The S1F costs noticeably more, and you do feel that at checkout. But on the road, that extra spend buys real, daily improvements: significantly more range, much better suspension, higher load capacity, and a more refined ride. Over a couple of years of regular commuting, those differences add up. Pure euros-per-feature, the Acer looks attractive; euros-per-quality-of-commute, the S1F pulls ahead if you actually use its strengths.
Service & Parts Availability
Acer as a company is huge, but their scooter line is still relatively young. That means basic warranty support through electronics retailers is fine, yet the deeper ecosystem of third-party parts, how-to guides and specialist repair shops is still catching up. Simple things - tyres, brake pads - are easy enough; proprietary parts can involve more hunting or waiting.
InMotion has been building personal electric vehicles for longer and has a more established network in the PEV world. European distributors often stock spares, and there is a decent community of owners and independent shops familiar with their design quirks. You still won't find parts in every corner bike shop, but if you are the sort who keeps a vehicle for several years, the S1F currently has the healthier support ecosystem.

Final Verdict - Which Should You Choose?
If your commute is modest, your budget is firm, and you want something that feels a step up from rental fare without going overboard, the Acer Predator Storm does the job. It looks the part, has enough poke to be fun, and offers a healthy battery for the money. It's not a bad scooter - just one that quietly sits in the "good enough" middle lane.
If you are riding further, riding more often, heavier, or simply care about your spine and knees, the InMotion S1F is the better tool. The extra money buys you noticeably more comfort, more range, and a more confidence-inspiring ride, particularly on bad roads or under heavier loads. You feel it every single day you ride it.
In plain terms: choose the Predator Storm if price and slightly better portability are your priority and your rides are short to medium. Choose the S1F if you actually plan to live on this scooter - long commutes, big rider, frequent use - and want something that feels purpose-built for that life.
