Hiboy S2 Max: Everything You Need to Know
The Hiboy S2 Max is a folding scooter, not a Class 1–3 e-bike. The product page showed $489.99 from $834.99: 19 mph, 40 miles, 500W rated, 650W peak, 48V 11.6Ah, and both 40 lb and 18.8 kg. No suspension.

The short answer
The Hiboy S2 Max is the long-claim folder in this trio. The page showed $489.99 against $834.99, at 19 mph and 40 miles, 500 watts rated and 650 watts peak. The pack is 48 volts and 11.6 amp-hours, 556.8 watt-hours, unprinted. One line says 40 pounds. Another says 18.8 kilograms, about 41.4 pounds, not 40. No suspension is listed.
The Hiboy S2 Max is a folding commuter scooter, not a Class 1, 2, or 3 e-bike, and it is not the S2 Pro. The product page showed $489.99 against an $834.99 regular price. The tiles say 19 mph, 40 miles, 10-inch self-healing tires, no suspension, a 500-watt motor, and a 48-volt 11.6 amp-hour battery. The modal prints a 500-watt rating, a 650-watt peak, 40 pounds and, in the same cell, 18.8 kilograms, a 20 percent grade, a 220-pound load, and a 6-to-7-hour charge. Eighteen point eight kilograms is 41.4 pounds, not 40. Forty-eight times 11.6 is 556.8 watt-hours. The page does not print that. Hiboy’s side-by-side matches that sale tag, the 40-mile claim, the 48-volt pack, the 650-watt peak, and the missing suspension, and it adds UL 2272. A July 29, 2026 blog prints $490. The S2 collection view marked this model sold out at $489.99 from $834.99. Hiboy’s own FAQ says the Max’s range claim is 40 miles against 25 on the Pro, and that the Max adds regen and self-healing tires. The row on this desk’s list links here.
Forty pounds and 18.8 kilograms on one line
Hiboy’s S2 Max product modal, the compare grid, the July 29, 2026 blog, and the collection tile.
| Product modal | The other Hiboy print | |
|---|---|---|
| Price | $489.99 sale, $834.99 regular. | Blog: $490. Side-by-side: $489.99. Collection view: that same sale tag from $834.99 and sold out. The dollar is stable. The stock mark is not. |
| Speed | 19 mph. | The chart also prints 19. The blog does not print a faster Max. Same claimed top speed as the cheaper S2, which is the point of reading the pack instead. |
| Range | 40 miles, also written 64 km. No rider weight. | Comparison table and the FAQ against the Pro: 40 versus 25. The blog prints 40. Sixty-four kilometers is 39.8 miles. Close, and still a claim. |
| Motor | Rated 500W. Peak 650W. | The comparison table matches both. The blog’s peak column says 650W. This is the page where Hiboy’s peak agrees with itself. The Pro’s does not. |
| Battery | 48V 11.6Ah. No watt-hours. | Forty-eight times 11.6 is 556.8. The comparison table prints the same 48V 11.6Ah. Charge is 6 to 7 hours on the modal. That is not the Pro’s 36-volt pack. |
| Weight | 40 lb, and 18.8 kg in the same cell. | 18.8 kg is 41.4 lb. The comparison table’s weight cell was not a cleaner third number this crawl. Do not average 40 and 41.4. Quote both and say Hiboy printed both. |
| Chassis | 10-inch self-healing. Suspension: none. 20% grade. 220 lb. Age 16 to 50 on the modal. | Comparison table: no suspension, 20%, UL 2272. The Pro modal claims rear shocks and a 15-degree hill. The FAQ is right that these are different scooters. The modal’s age cap is 50 here and 60 on the S2. |
The Max is Hiboy’s long-range S2, on a claim. It is not a suspended scooter. Self-healing is Hiboy’s word for the tire, not a test of how many punctures it shrugs off. The kilogram in parentheses is the tell. If the scale at the door says 40, the parenthetical says otherwise. Believe that you have two numbers, not a rounded one, until Hiboy deletes one of them.
Forty claimed miles do not create pedals. A 650-watt peak on a kick scooter is not a Class 2 sticker, and UL 2272 does not add a crank.
Who it is for
Buy it if the 40-mile claim is why you stepped past the Pro, and you do not need the rear shocks the Pro modal advertises. Skip it if the collection’s sold-out mark is the page you are actually on. The S2 Pro is the 25-mile scooter with the peak-watt argument. The Hiboy S2 is the $299.99, 17-mile scooter. The GMAX Ultra is GoTrax’s 45-mile claim, on a cart that does not say Ultra 2.
It fails the class chart. No pedals. Five hundred fifty-six point eight watt-hours divided by 40 miles is about 14 watt-hours a mile, on math Hiboy did not print. The watt-hour page is the arithmetic.
Questions people ask
Why is 18.8 kilograms refused as a synonym for 40 pounds?+
Eighteen point eight kilograms times 2.20462 lands near 41.4 pounds. The other line says 40 pounds flat. The gap is about a pound and a half. Publish both figures. Do not “correct” the kilogram line down to 40 and pretend the page agreed with itself. A conversion you did is your sentence, not the shop’s.
Which tag is the product page, and which is a dead collection?+
The button was $489.99 against an $834.99 regular. A collection view has marked this trim sold out on at least one pass. The row’s price is the product-page button, not a leftover grid tile. If the button disappears, the spec sheet can stay live while checkout is closed. Date whichever screen you captured.
Where is the suspension a Max suffix makes people expect?+
Nowhere on the chassis block this crawl. The page does not add a fork or a rear shock to this trim. The extra relative to the shorter folders is the 40-mile claim and the 48-volt pack, not travel. Read that chassis block before the suffix talks you into a bump the copy never promised.
Is the 40-mile sentence a ridden test or a brochure?+
It is a claim. No rider weight was attached in the lines this desk read. Forty-eight times 11.6 is 556.8 watt-hours, which the page does not print. Dividing that energy by 40 miles is desk arithmetic, not a loop. No pedals, so the class chart still says scooter even when the pace is 19.

What Is a Class 1, 2, and 3 E-Bike?
Class 1 is pedal-assist to 20. Class 2 adds a throttle to 20. Class 3 is pedal-assist to 28. A Tuttio is none of these. The sticker is not the trail.
