Hiboy S2: Everything You Need to Know
The Hiboy S2 is a folding budget scooter, not a Class 1–3 e-bike. The product page showed $299.99 from $599.99: 19 mph, 17 miles, 350W rated, 500W peak, 36V 7.5Ah, 35.49 lb. A July 2026 blog prints 35.5 lb.

The short answer
The Hiboy S2 is the short-range folder, not the Pro and not the Max. The product page showed $299.99 against $599.99, at 19 mph and 17 miles, 350 watts rated and 500 watts peak. The pack is 36 volts and 7.5 amp-hours, 270 watt-hours, unprinted. The page weighs it at 35.49 pounds. A July 29, 2026 blog says 35.5. A lock bundle is $339.99.
The Hiboy S2 is a folding budget kick scooter, not a Class 1, 2, or 3 e-bike, and it is not the S2 Pro or the S2 Max. The US product page showed $299.99 against a $599.99 regular price. The tiles say 19 mph, 17 miles, 8.5-inch honeycomb tires, rear suspension, and a 350-watt motor over a 36-volt 7.5 amp-hour battery. The specification modal prints a 350-watt rating and a 500-watt peak, 35.49 pounds, a 15 percent grade, a 220-pound load, a 3-to-5-hour charge, an electronic brake plus a disc, IPX4, and an age band of 16 to 60. Thirty-six times 7.5 is 270 watt-hours. The page does not print that. Hiboy’s comparison table agrees on the $299.99, the 17 miles, the 7.5 amp-hours, the 350/500 split, and 35.49 pounds, and it adds UL 2272, which the modal this crawl did not. A July 29, 2026 Hiboy blog prints 35.5 pounds and a 500-watt peak. A cable-lock variant is $339.99 from $599.99. The row on this desk’s list links here.
One modal, a side-by-side, and a blog that rounded the scale
Hiboy’s S2 product modal, the compare grid, the July 29, 2026 series blog, and the cable-lock variant.
| S2 product modal | The other Hiboy print | |
|---|---|---|
| Price | $299.99 sale, $599.99 regular. | Cable-lock variant: $339.99 from $599.99, and the page says that price does not stack with other discounts. The chart also prints $299.99. |
| Speed | 19 mph. | The compare grid and the blog’s S2 row also print 19. That part agrees. It is still not the Pro’s or the Max’s motor. |
| Range | 17 miles. No rider weight on the tile. | Hiboy’s side-by-side and the blog also print 17. The Pro’s claim is 25. The Max’s claim is 40. Do not borrow either. |
| Motor | Rated 350W. Peak 500W. | The comparison table matches. The blog’s peak column also says 500W for the S2. A collection tile that only says “350w” is the rated figure, not a denial of the peak. |
| Battery | 36V 7.5Ah. No watt-hours. | Thirty-six times 7.5 is 270. The side-by-side prints the same 36V 7.5Ah. The blog prints 7.5Ah and skips the voltage on that cell. Charge on the modal is 3 to 5 hours. That grid says the same. |
| Weight | 35.49 lb. | Hiboy’s matchup prints 35.49. The July 29, 2026 blog prints 35.5. That is a rounding, not a second scale, unless Hiboy weighs it again. Quote 35.49 if you are quoting the modal. |
| Chassis | 8.5-inch honeycomb. Rear suspension. E-brake and disc. 15% grade. 220 lb. IPX4. | That grid adds UL 2272 and a rider-height band of 4 feet 11 inches to 6 feet 1 inch. The modal prints age 16 to 60 and does not print UL. Fifteen percent is not 15 degrees. |
The S2 is the rare Hiboy page where the modal and the comparison table mostly agree. The fight is next door: the Pro’s peak is 600 watts on its modal and 750 on the comparison table. Do not let that argument leak onto this 350-watt rating. Honeycomb tires are solid. They are not the pneumatic tires on a DK dirt bike, and they are not the Max’s self-healing pair.
Nineteen miles an hour and a 350-watt rating do not make a Class 2 bicycle. UL 2272, where the comparison table bothers to print it, is a fire standard.
Who it is for
Buy it if $299.99 is the button and 17 miles is enough of a claim. Buy the lock bundle only if you wanted that cable and you accept $339.99. S2 Pro is the 25-mile, 10-inch cart, with a peak Hiboy cannot keep consistent. S2 Max is the 40-mile, 48-volt cart. The GXL V2 is the other sub-$300 folder on this list, at 15.5 mph and a 12.5-mile US tile.
It fails the class chart. No pedals. Two hundred seventy watt-hours divided by 17 miles is about 16 watt-hours a mile, and the watt-hours are this desk’s multiplication, not Hiboy’s label. The watt-hour page is the arithmetic.
Questions people ask
Why are 35.49 pounds and 35.5 pounds both in the weight slot?+
The product page prints 35.49 pounds. The July 29, 2026 blog prints 35.5. Those are a hundredth of a pound apart and they are still two sentences. Do not round one into the other and then call the result a third scale. The tiles do not print watt-hours. Thirty-six times 7.5 is 270, which you can compute and which the page never labels.
What does adding the lock actually change on the receipt?+
The lock bundle button is $339.99. You are paying for the cable, not for a larger pack or a faster cap. The 17-mile claim and the 19 mph claim stay on the base machine. If you did not want the cable, the lower button is the one that matches this row. A bundle is an accessory, not a quiet motor upgrade.
Where does the fire mark show up, and where is it missing?+
UL 2272 shows up on a comparison table. It does not show up on the product modal this crawl. A table cell is not the same as a badge on the buy box. Read the modal you are checking out. A family chart can copy a mark from a sibling and leave the window you are buying unmarked.
Do 19 mph and a 350-watt rating make this folder Class 2?+
No. There are no pedals. Nineteen miles an hour is under 20, and 350 rated watts is under 750, and the test still wants pedals. The Pro is the 25-mile cart whose peak the brand does not keep on one number. The Max is the 48-volt cart. This button is the 17-mile one. The class chart does not bend for a fire listing.
