The Hiboy S2 Pro is the commuter with the most range on tires that cannot go flat: 417.6 Wh (36 V, 11.6 Ah) and a 500 W rated motor (600 W peak), which we estimate covers about 15 to 19 miles at full speed, or about 7 miles each way. Hiboy claims 25 miles at a constant 11.4 mph with a 165 lb rider. It tops out at 19 mph, with a rear disc and electronic brake, rear dual shocks, 10-inch honeycomb tires that never need air, a headlight, sidelights and a taillight. Hiboy lists no turn signals, and the water rating is IPX4, which covers splashes, so a downpour is a reason to leave it home.
Hiboy's documents disagree on its weight (37.4 lb on the product page, 39.7 lb in the manual, 35.9 lb on Amazon) and its charge time (4 to 6 hours, 6 to 7 hours, and 8 hours on Amazon). Hiboy publishes UL LLC certificates for it, UL 2272 for the electrical system and UL 2271 for the battery pack, linked from its product page; we could not check them in UL's directory, which needs a login. No CPSC recall found for the Hiboy S2 Pro as of October 2026. Its 19 mph top speed is under New York's 20 mph e-scooter limit and above California's 15 mph limit.
Who it suits: riders under 220 lb who would rather never fix a flat on the way to work. Skip if you ride in heavy rain or weigh over 220 lb. Read the Hiboy S2 Pro review.
