How fast is the Hiboy KS4 Pro?
Hiboy rates it for 19 mph from the 500W motor, with 750W of peak power for pulling away and for hills. That keeps it under the 20 mph limit New York sets for electric scooters; see electric scooter laws in NYC. Cruise control holds your speed without the throttle, and the app switches between S and D riding modes and between Zero Start, where the motor starts from standstill, and Non-zero Start, where you kick off first.
How far does the Hiboy KS4 Pro go on a charge?
Up to 25 miles on Hiboy's rating, from the 36V 11.6Ah battery, in good conditions. A heavier rider, hills, wind, cold and riding at full speed all bring it down. A full charge takes 4 to 6 hours. For more range, see the best long-range electric scooters.
How much does the Hiboy KS4 Pro weigh?
40.6 lb, and it folds to 20.7 inches high. That's carryable up a flight of stairs or into a car trunk, but heavier than the lightest commuters; see the lightest electric scooters.
Tires, suspension and brakes
The 10-inch honeycomb tires are solid, so they can't leak air or go flat, and the dual rear shock absorbers take out some of the road that solid tires pass through. Braking pairs a front electronic brake (EABS) with a rear disc brake, which Hiboy sets to act together so neither wheel does all the work. For how tire types compare, see electric scooter tires.
Is the Hiboy KS4 Pro waterproof?
No. It's rated IPX4, which covers light rain and splashes, not heavy rain or deep water. Water damage isn't covered by warranty, and never charge an electric scooter that is wet or has a swollen battery; bring it straight in. See can you ride an electric scooter in the rain.

Same speed, same rated range and the same size battery. The KS4 Pro adds 150W more peak power, the bigger smart LED dashboard and extra app functions, for 3.2 lb more. If you want the lightest of the two, the S2 Pro; if you want the extra pull and the dashboard, the KS4 Pro.

Who is the Hiboy KS4 Pro for?
- Good fit: commuters who want flat-free tires, a clear dashboard and app control at a low price, riding up to about 25 miles between charges, up to 220 lb.
- Look elsewhere: if you weigh more than 220 lb, ride in heavy rain, want air-filled tires for a softer ride or want more than 19 mph.
