I’ve been a loyal fan of Hiboy scooters for a while now. Over the years, I’ve had the pleasure of owning several models, including the S2 Pro and the S2R Plus. When I heard about the KS4 Pro, which sits right between the S2 Pro and S2R Plus in terms of specifications, I was eager to give it a try. After a month of leisurely rides, I’m ready to share my thoughts on the KS4 Pro’s performance, design, features, and overall reliability. As someone who’s experienced with electric scooters, I hope to provide you with some useful insights if you’re considering this model.
Design and Assembly of the Hiboy KS4 Pro
Sleek and Functional Design
The Hiboy KS4 Pro boasts a sleek, modern design that’s both functional and visually appealing. The scooter arrived well-packaged, and the assembly process was straightforward. All I had to do was attach the handlebars using the provided screws. The scooter felt secure and well-built, ready for action right out of the box.
Size and Fit
The KS4 Pro is designed to be compact yet sturdy. Here are some of its key dimensions:
- Handlebar Width: 18.9 inches
- Deck Length: 18.1 inches
- Deck Width: 6.1 inches
- Overall Length: 45.3 inches
- Overall Height: 48.2 inches
- Standing Height: 41.3 inches
- Folded Height: 20.7 inches
- Maximum Load: 220 lbs.
- Net Weight: 38.5 lbs.
These dimensions make it a comfortable fit for most riders, offering a good balance between portability and stability.
Performance of the Hiboy KS4 Pro
Powerful Motor and Battery
One of the standout features of the KS4 Pro is its powerful 500W motor, which peaks at 750W. This motor, combined with the 36V 11.6Ah battery, allows the scooter to reach a top speed of 19 mph. Even with my 190 lbs. weight, the scooter accelerated smoothly and effortlessly to its maximum speed on flat terrain.

When it comes to inclines, the KS4 Pro can handle slopes up to 15 degrees. I tested it on various hills around my local golf course. While it managed moderate inclines well, it struggled with steeper ones, requiring me to push it like a traditional scooter.
Impressive Battery Range
Hiboy claims that the KS4 Pro can travel up to 25 miles on a single charge under ideal conditions. To test this, I took the scooter on a full charge and completed a loop, monitoring the battery using the Hiboy App. Although the app’s distance measurement was slightly off (showing 7.0 miles instead of the actual 9.7 miles), the battery usage seemed to align with the advertised range. I ended my ride with the battery at 54%, suggesting a realistic range of around 21.08 miles, considering my weight and riding speed.

Safety and Features of the Hiboy KS4 Pro
Brilliant Lighting System
Riding safely at night is a priority for many, and the KS4 Pro excels in this area. It features a non-adjustable headlight, vibrant sidelights, and a brake light. The sidelights are particularly striking, offering a cool red glow that’s highly visible in low-light conditions. The integrated display is also a highlight, providing real-time information about speed, battery status, and more.

Hiboy App Integration
The Hiboy S2 App enhances the riding experience by allowing you to view statistics, monitor battery life, and control various features. You can lock and unlock the scooter, activate cruise control, and switch between different riding modes (ECO, D, and S gears). The app’s connectivity and functionality make managing the scooter convenient and straightforward.
Braking and Tires of the Hiboy KS4 Pro
Reliable Braking System
The KS4 Pro features a dual braking system that includes a rear disc brake and front electronic ABS. This combination ensures balanced braking, preventing issues like rear wheel slippage or sudden front wheel stops. I found the brakes to be very responsive and effective, easily bringing the scooter to a stop from full speed with minimal effort.

Honeycomb Tires and Suspension
The scooter’s 10-inch honeycomb tires are designed for durability and low maintenance, eliminating the risk of air leaks. While they provide decent stability, they also transmit a significant amount of vibration to the handlebars. Despite the rear shock absorption system, the ride felt somewhat rough compared to scooters with air-filled tires. The rear shock seemed too stiff and didn’t noticeably compress during my rides. To improve comfort, softer handlebar grips or an adjustable shock absorber could be beneficial.

Conclusion

Overall, the Hiboy KS4 Pro Electric Scooter offers a blend of power, range, and convenience that’s hard to beat at its price point. Its robust motor and long-lasting battery make it an excellent choice for city commuting and short-distance travel. However, the ride comfort could be improved with better suspension and tire options. But, if you’re looking for a reliable and efficient scooter for your daily commutes or weekend adventures, the KS4 Pro is definitely worth considering.
