Hiboy S2 Electric Scooter

Hiboy rates the motor at 350 W, with 500 W peak. There are two modes: Drive tops out at about 13 mph and Sport at 19 mph (Hiboy's FAQ says 18.6 mph in Sport), and the Hiboy app adds a lock, cruise control and speed settings. Its 19 mph top speed fits New York's e-scooter definition (VTL §114-e: no more than 20 mph and under 100 lb) and is above California's 15 mph limit (Vehicle Code §22411), so California riders must keep it at 15 mph or below, which Drive mode does. Scooters are not e-bikes, so the US e-bike classes do not apply. California also requires a driver's license or instruction permit (§21235) and a helmet under 18. New Jersey's legal e-scooter must be under 19 mph (and 750 W or less), so at 19 mph the S2 falls outside that category; New Jersey treats it as a motorized scooter that cannot be registered, which limits it to private property there. Pennsylvania does not allow e-scooters on public roads; HB 1633 would change that and has not passed. Check your city's rules as well.

Hiboy claims 17 miles and, unusually, publishes how it got there: a 165 lb load at a steady 11.4 mph on flat ground at 77°F with no wind. Most riders are heavier and faster than that. We estimate range by dividing battery capacity by 22 to 27 watt-hours per mile, a band taken from published full-speed tests and adjusted to a 175 to 180 lb rider. For the S2's 280.8 Wh that is about 10 to 13 miles a charge at full speed; at the product page's 7.5 Ah it would be 10 to 12. In those tests, scooters covered a median 59% of their advertised range, which would put the S2 near 10 miles. Riding slower in Drive mode should add some. This is an estimate from the spec sheet; we have not ridden the S2. The manual gives a 5 to 6 hour charge on the 42 V, 1.5 A charger (the product page says 3 to 5 hours).

Both wheels carry 8.5-inch honeycomb tires: solid and airless, so there is nothing to puncture, though solid tires pass more road vibration to the rider than air-filled ones. Two rear spring shocks take some of the edge off. Stopping is a rear disc brake plus an electronic regenerative brake. Hiboy rates the S2 IPX4, which means splash resistance, so avoid heavy rain and deep puddles. It weighs 35.5 lb, carries up to 220 lb including anything the rider holds, and folds to 44.1 x 16.7 x 19.3 in per the manual (the product page says 45.7 x 17.0 x 19.3 in). Hiboy puts the maximum climb at about 15%, enough for moderate city hills. It has a headlight, side lights and a taillight, with no turn signals, and Hiboy's stated operating range is 14 to 104°F. The warranty runs one year for the original owner and excludes battery capacity loss.

Hiboy publishes the paperwork. The UL badge beside the price on its S2 product page links UL LLC certificates of compliance: UL 2272 certificate UL-US-2422581-0 (report reference E535405-20240611) for the scooter's electrical system, and UL 2271 certificate UL-US-2422576-0 for the battery pack. We could not check the numbers in UL's own directory, which needs a login, so we report them as Hiboy's published documents. The same page's FAQ words it loosely, calling the battery "UL 2272 certified", although a battery pack on its own falls under UL 2271; the certificates cover both. Hiboy's Amazon listing says the S2 passed UL 2272 testing and names a lab. That matters in New York City, where Local Law 39 has required UL 2272 for e-scooters sold there since September 16, 2023, and in California, where SB 1271 has required UL 2272 battery testing for motorized scooters sold there since January 1, 2026. The CPSC proposed a federal standard based on UL 2272 in June 2026; it is not final. No CPSC recall found for the Hiboy S2 as of October 2026.

Four scooters an S2 shopper is likely to weigh it against, the last for riders who want to sit:

• Segway E3 Pro ($599.99 as of Oct 22, 11:10 AM EDT, subject to change): the stronger scooter on paper. Segway lists a 368 Wh battery (we estimate 14 to 17 miles), 10-inch tubeless air tires, front and rear suspension, IPX5, a 265 lb limit and a two-year limited warranty. It weighs 40.1 lb, 4.6 lb more than the S2.
• MAXSHOT V1 ($149.99 as of Oct 22, 11:10 AM EDT, subject to change): #2 in Amazon's Electric Scooters on October 18, 2026, with a similar 350 W motor, a 19 mph top speed and 31 lb on paper. Every MAXSHOT figure comes from its Amazon listing, with no maker site we could verify; its brakes are a drum plus an electronic brake with no disc, and it states no IP rating.
• WAWSCOTE W3C ($159.99 as of Oct 22, 11:10 AM EDT, subject to change): the same 280.8 Wh battery size with a 500 W rated motor, IPX4 and a UL 2272 line naming TÜV Rheinland, on 8.5-inch honeycomb tires with no suspension and no disc brake. Its warranty is 180 days, and the same W3C sells as the Oslich.
• Qlaway K078L ($174.99 as of Oct 22, 11:10 AM EDT, subject to change): if you want to sit, a 350 W, 19 mph scooter with a seat on an 11-liter storage box and a 288.6 Wh battery (we estimate 11 to 13 miles). Hiboy also sells a seat kit for the S2 on Amazon; our seat guide compares both routes.

Buy the S2 if you weigh under 220 lb with your bag, your round trip is under about 10 miles on paved streets, and you never want to fix a flat. It also suits California riders, since Drive mode stays under the state's 15 mph limit. Skip it if your route has steep hills, long stretches of broken pavement or regular rain, or if you need more than about 10 miles at full speed: the Hiboy S2 Pro ($422.95 as of Oct 22, 11:10 AM EDT, subject to change) carries a 417.6 Wh battery (we estimate 15 to 19 miles) and a 500 W rated motor. Riders over 220 lb should look at the Segway E3 Pro above, rated for 265 lb.
