Questions riders ask

How far does the Hiboy KS4 Pro Electric Scooter go on a charge?

The listing claims 25 miles. Claims assume a 165 lb rider at eco speed on flat ground. Our physics estimate for a 180 lb rider cruising at 15 mph is about 20.132 miles; cold weather takes another 10 to 30 percent and hills more. Run your own numbers in the range calculator.

What is the weight limit of the Hiboy KS4 Pro Electric Scooter?

The listing we read does not state a max load. Ask the seller or check the manual before buying for a heavier rider; common ratings are 220, 265 and 300 lb for adult scooters and 110 to 176 lb for kids models.

Can the Hiboy KS4 Pro Electric Scooter climb hills?

With its 500W rated motor and a 180 lb rider, physics puts it at about 12 mph on a 5 percent grade, 7.6 mph on 10 percent and 5.4 mph on 15 percent. Short hills can borrow peak power (750W listed); long ones cannot. The hill climb calculator takes your exact grade and weight.

What helmet should I wear with the Hiboy KS4 Pro Electric Scooter?

A CPSC-certified bike helmet at minimum; for commuting, one with built-in lights and MIPS is worth the extra. Size it by head circumference with the helmet size calculator.

Wear a helmet every ride, and check your state and city rules on age, speed and where scooters may ride. This page is researched guidance, not professional, legal or medical advice. Specifications come from each product listing and can change; confirm on the listing before you buy.
