I recently bought the Hiboy KS4 Pro electric scooter, and after riding it for a few weeks, I can confidently say it’s one of the best investments I’ve made for my daily commute. I wanted something affordable, reliable, and powerful enough to handle city roads, and the KS4 Pro has mostly delivered on those expectations. The scooter arrived well-packed and was easy to assemble — just unfold, tighten a few screws, and it’s ready to ride. The build quality feels solid and premium for its price. The matte black finish with side lighting gives it a sleek, modern look, and the digital display is bright and easy to read, even in daylight. I also like the Hiboy app, which lets me lock the scooter, check speed, and monitor battery life from my phone. It’s simple, but it gets the job done. Performance-wise, the KS4 Pro is impressive for a mid-range scooter. The 500-watt motor has plenty of power for flat city rides, and I’ve reached close to its advertised top speed of 19 mph on straight roads. Acceleration is smooth and steady, and the throttle responds quickly. On small inclines, it still performs well, although it does slow down a bit on steeper hills. The scooter feels stable, and the wide deck makes it comfortable to stand on during longer rides. The 10-inch honeycomb tires are both a blessing and a drawback. I love that they’re solid and puncture-proof — no need to worry about flats — but they make the ride a little rougher on uneven roads. The suspension system helps a bit, but you can still feel bumps and cracks, especially at higher speeds. For city streets and bike lanes, though, the comfort level is acceptable. Battery life is another strong point. Hiboy claims around 25 miles per charge, and while I haven’t reached that full distance, I consistently get about 17–20 miles depending on speed and terrain, which is still very good. Charging takes around 5 to 6 hours, and the charger is compact enough to carry in a backpack if needed. Braking is reliable with its dual-brake setup — a rear disc brake and front electronic regenerative braking. The response time is quick, and it feels safe even when stopping from higher speeds. The bright headlight and rear brake light are great for night rides, and the side lighting adds extra visibility, which I really appreciate for safety. If I had to point out downsides, I’d say the scooter is slightly heavy at about 38 pounds, and carrying it upstairs can be tiring. The ride could be smoother on rough pavement, and the app sometimes disconnects. But overall, these are minor compared to how well it performs. In summary, the Hiboy KS4 Pro is a dependable, fun, and stylish electric scooter that perfectly suits everyday city commuting. It offers a great balance of speed, range, and safety features for its price. I’d happily recommend it to anyone looking for a solid, hassle-free ride for daily use.

The review will be a bit long but I will be as complete and honest as possible from my point of view. This is my second scooter and the first from Hiboy. Overall, for the price of $400 it is pretty good! You won't find anything better for that price range since they always have a discount on that model, as for the scooter the electric brake is very strong (quite good) the bad thing is that it is not independent, it is activated with the same lever as the rear brake and just like the s2/pro it was better separately although it is not a big problem, I loosen the rear brake a little to be able to activate only the electric one when I pull the lever a little, and compared to my other scooter where it was automatic it is infinitely better to be all manual, since an automatic electric brake makes you spend more energy than it regenerates, the lights are very good but you can't deactivate the ones on the sides or with the app, and speaking of the app it is extremely simple and with very few options, the worst part, but at least it is functional (better than nothing), something that had me worried is that when using the lights and moving the scooter the motor makes a very audible electrical noise compared to my previous scooter which was totally silent, I consulted with hiboy and they told me that I can be calm that it is normal when using the lights and moving the scooter. just like sometimes the battery level after a trip can drop 5% when you turn on the lights (it seems like a lot to me but they say it's normal too) but it goes back up when you turn them off, it could be because it's a large battery. The rear suspension is very hard and only works when jumping or falling, but the honeycomb tires are much better than the hollow ones and, being 10 inches, the ride is more cushioned.

This product has held up very well ove the past 12 months, i was very skeptical about how abour making this purchase, and then i did my research and made some comparisons and came to the conclusion that this was worth the money. I Highly recommended this purchase to anyone who likes the balance of performance and value. I easily trek around one side of town, to the other on a single charge, and i am also able to fold it up and take it with me on the bus if i need to.
