Real rides. Real notes. No hype.
The Hiboy KS4 Pro is a practical commuter scooter that gets a lot of the important things right for the money.
It offers a usable 19 mph top speed, a solid maintenance-friendly tire setup, balanced braking, app support, and better lighting than many budget models.
It is not the softest-riding scooter in this class, and it is not the strongest hill climber either, but for city riders who want a straightforward, feature-rich commuter around the $400 mark, it makes a strong case.
Quick Verdict
The Hiboy KS4 Pro is a good fit for riders who want an affordable commuter scooter with low tire maintenance, good visibility, and a polished everyday feature set. It feels more complete than many entry-level scooters, but it still rides firm on rough pavement and loses momentum on steeper hills.
Best for
- Urban commuters riding mostly smooth to average pavement
- Riders who want to avoid flats and tire maintenance
- Buyers who value app features, lighting, and balanced braking
Not ideal for
- Riders with rough roads as part of the daily route
- Heavier riders dealing with frequent or steeper hills
- People who need to carry a scooter up stairs every day
Biggest strength
The KS4 Pro combines a commuter-friendly 19 mph top speed, app support, strong visibility features, and flat-free tires in a package that feels well thought out for the price.
Biggest trade-off
The solid tires help with reliability, but they also make the ride firmer than air-tire alternatives, especially on cracked pavement and sidewalk joints.
At a Glance
The Hiboy KS4 Pro uses a 500W rear motor with 750W peak output, a 36V 11.6Ah battery, 10-inch honeycomb solid tires, rear suspension, front EABS regenerative braking, and a rear disc brake. Claimed range is up to 25 miles, top speed is 19 mph, and the scooter supports the Hiboy app for ride data, lock and unlock functions, cruise control, ride modes, and some setup options.
On paper, this is a fairly complete commuter setup. In practice, it works best as a city scooter for short to moderate commutes where reliability and convenience matter more than outright power or plush comfort.

Setup experience
Assembly took about 10 to 15 minutes. Most of it was attaching the handlebar, tightening the six screws, and pairing the app. I did not run into any major setup problems, though I would still double-check handlebar alignment, screw tightness after the first ride, and app pairing before leaving for a longer trip.
What the Hiboy KS4 Pro Gets Right
The KS4 Pro is easy to understand once you start using it. It is not trying to be a performance scooter or an ultra-light last-mile tool. It is a commuter scooter with a sensible top speed, enough battery for typical city use, and a feature list that feels slightly more polished than many similarly priced options.
The standout strengths are the flat-free 10-inch honeycomb tires, the dual braking setup, the lighting package, and the app support. None of those features alone make it special, but together they make the scooter feel practical and complete.
That matters in this category. Plenty of budget scooters hit one or two headline specs, then fall short in daily use. The KS4 Pro does a better job of balancing the overall commuter experience.
Real-World Speed and Power
The Hiboy KS4 Pro feels smooth rather than punchy. That is one of the first things I noticed. It gets moving well enough for normal city commuting, and 19 mph is a perfectly reasonable top speed for bike lanes, neighborhood streets, and short cross-town trips. But it does not have the hard launch or stronger mid-speed shove you get from more powerful scooters.
For everyday commuting, that is not necessarily a problem. In fact, some riders may prefer the more controlled delivery. The KS4 Pro feels predictable and manageable rather than jumpy. That makes it easier for less experienced riders to live with.
Where its power limit shows up is on hills. Small commuter hills are manageable, but once the grade gets steeper, speed drops off noticeably. For a rider around 180 pounds, I would expect mild hills to be fine, but steeper climbs will take patience and may need a bit of kick assist. If your route is mostly flat or only mildly rolling, this is acceptable. If your area has frequent climbs, the KS4 Pro starts to feel average rather than impressive.
Ride Quality and Comfort
Ride comfort is decent for a scooter with solid tires, but it is still a solid-tire scooter. That is the key point.
The rear suspension helps. It takes some sharpness out of smaller hits and keeps the scooter from feeling overly harsh on ordinary city pavement. On smoother roads, the KS4 Pro feels stable and controlled. But once you get onto rougher sections, cracked asphalt, patchwork pavement, or sidewalk joints, more of the surface comes through than it would on a scooter with pneumatic tires.
That does not make it uncomfortable in an absolute sense. It just makes the trade-off obvious. Honeycomb tires are great for reducing flats and cutting maintenance headaches, but they do not isolate vibration as well as air-filled tires. If your commute is mostly decent pavement, this will not be a dealbreaker. If you ride rough streets every day, it becomes one of the scooter’s more noticeable weaknesses.
The deck and overall stance feel commuter-friendly, and the scooter is easy to control on normal paved surfaces. I found the handling predictable rather than sporty. It tracks cleanly, feels easy to place in a lane, and does not ask much from the rider. That suits its commuter role well.
Braking and Safety
Braking is one of the stronger parts of the KS4 Pro.
The combination of front EABS regenerative braking and a rear disc brake gives the scooter a balanced, predictable feel in normal city stops. It does not feel sketchy, grabby, or overly abrupt. For everyday commuting, that matters more than flashy spec language. The scooter slows in a way that feels controlled and confidence-inspiring.
That balance also helps newer riders, because the braking behavior feels easier to manage than some single-brake budget scooters that can feel uneven or abrupt.
The lighting package is another plus. The headlight, taillight, brake light, and side lighting make the KS4 Pro easier to notice in low-light riding. I would not describe the headlight itself as premium, but overall visibility looks better than average for the price. In real commuting, being seen often matters just as much as seeing far ahead, and the KS4 Pro does a good job there.
It also helps that the scooter is UL2272 tested, which adds some reassurance on the electrical safety side.
Range and Battery Reality
Hiboy lists the KS4 Pro at up to 25 miles per charge, with some materials showing roughly 21.7 to 24.8 miles. As usual, that is best understood as a controlled-condition estimate rather than a number most riders should plan around.
In real use, I would expect about 17 to 21 miles for many riders, depending on rider weight, speed, hills, temperature, stop-and-go riding, and how much time is spent in Sport mode. That is still respectable for this class and price point. It is enough for many daily commutes, errands, and casual city rides.
What I would not do is build a commute plan around the full 25-mile claim unless conditions are ideal and the rider is lighter than average. For a 180-pound rider mixing city riding and normal pace changes, the real-world number will usually land below that.
The roughly 417.6Wh battery size makes sense for the scooter’s role. It is not oversized, but it is large enough to support what this scooter is meant to do. Charging time is around 7 hours, which is typical enough for overnight charging.
App, Features, and Daily Usability
One of the better surprises with the KS4 Pro is how complete the feature set feels at this price.
The Hiboy app adds genuine everyday usefulness rather than just existing as a marketing extra. It supports ride stats, battery level, lock and unlock, cruise control, self-check, start mode settings, and ride mode selection. That helps the scooter feel more modern and better integrated than stripped-down budget models.
The included phone holder is also a nice bonus, especially for commuters using navigation. I would still be cautious about relying too heavily on a handlebar-mounted phone over rough streets, but for smoother city use it is a practical inclusion.
The folding design is straightforward, and the scooter fits the commuter use case well. It can go into a trunk, office, elevator, or compact storage spot without much drama. But portability has limits here. This is where the inconsistent listed weight matters. Amazon lists it at 38.5 pounds, while Hiboy’s current official page shows 40.6 pounds. Either way, this is not what I would call truly light. Carrying it briefly is fine. Carrying it up multiple flights of stairs every day is much less appealing.
So yes, it is portable in the sense that it folds quickly and stores easily. No, it is not especially portable in the sense of effortless daily carrying.
Build Quality, Tires, and Maintenance
The KS4 Pro’s flat-free tire setup is one of its most practical advantages. Many commuters simply do not want to deal with punctures, pressure checks, or tube replacements. The 10-inch honeycomb tires remove a lot of that worry.
That matters more than some enthusiasts admit. A scooter that asks for less maintenance can be the better real-world product for the average rider, even if it gives up some ride comfort.
Build quality looks appropriate for the category. Nothing in the setup or ride impressions suggests major red flags. I would expect normal solid-tire noise over bumps and expansion joints, but that feels more like a tire-character issue than a build-quality problem.
The rear suspension also helps the scooter avoid feeling overly basic. It does not transform the ride into something plush, but it makes the scooter more livable than a rigid solid-tire setup would be.
Where the Hiboy KS4 Pro Falls Short
The KS4 Pro is a good commuter, but it is not a hard scooter to criticize honestly.
First, the ride is still firm. Rear suspension helps, but solid tires are still solid tires. Riders on rough pavement will notice that quickly.
Second, hill climbing is only average. The 500W motor is enough for ordinary commuting, but not enough to hide the scooter’s limits on steeper grades, especially with a 180-pound rider or heavier.
Third, the near-40-pound weight means portability is only moderate. It folds well, but it is not especially pleasant to carry for long stair climbs or daily lift-heavy routines.
Fourth, the mixed listed weight figures are annoying. It is not a functional flaw, but it does make it harder for buyers to know exactly what to expect before purchase.
These are not small details. They define the kind of rider this scooter suits best.
Hiboy KS4 Pro vs Competitors
NIU KQi2 Pro
The NIU KQi2 Pro looks like the better choice if ride comfort matters more than a slightly higher top speed. Its 10-inch tubeless pneumatic tires should do a better job smoothing out rough pavement, and its IP54 weather rating is also appealing for commuters. The Hiboy counters with a quicker 19 mph top speed on paper and a strong overall feature set, but the NIU has the edge for comfort-focused buyers.
GOTRAX G4
The GOTRAX G4 is a close alternative if you want similar commuter speed with pneumatic tires and a slightly lower listed weight. It also offers a built-in lock, which some riders will appreciate. The Hiboy still has a convincing case if you prefer flat-free tires, strong lighting, and its specific app feature set, but the GOTRAX may be easier to live with on rougher pavement.
Who Should Buy the Hiboy KS4 Pro?
You should buy the Hiboy KS4 Pro if you want an affordable city commuter that feels complete, practical, and easy to live with. It makes sense for riders who value low maintenance, good visibility, decent real-world range, and predictable everyday performance.
You should skip it if your route includes frequent rough pavement, lots of steeper hills, or daily stair carrying. In those cases, an air-tire scooter or a lighter model may fit better.
Final Verdict
The Hiboy KS4 Pro is a well-rounded commuter scooter with a clear identity. It is not the softest-riding option, not the lightest to carry, and not the strongest climber, but it offers a practical mix of speed, reliability, features, and everyday usability that makes sense for a lot of riders.
What stands out most is that it feels finished. The app support is useful, the braking setup feels balanced, the lighting is better than expected for the price, and the flat-free tires remove one of the most common scooter ownership hassles. That combination gives it real value.
At around $400, the KS4 Pro is a good buy for city riders who want a dependable commuter with fewer maintenance headaches and a stronger feature set than many entry-level rivals. Just go in understanding the trade-offs: firmer ride, average hill performance, and only moderate portability. For the right rider, those are acceptable compromises. For the wrong rider, they will show up quickly.
