What $120 more actually buys
The jump from the Hiboy S2 to the Hiboy S2 Pro is not a cosmetic refresh. The motor grows from 350W to 500W, the wheels grow from 8.5 to 10 inches, and the claimed range grows from 17 to 25.6 miles, roughly a 50 percent jump. The Pro also states a clear 220 lb max rider weight, where the base S2's listing in our catalog does not list one for this model.
Range: closer in real life than the claim suggests
Claimed range assumes a 165 lb rider on flat ground at eco speed in warm weather; expect 60 to 80 percent of the claim in normal use on either model. That still leaves the Pro with a real advantage since the underlying claim itself is nearly 9 miles higher, useful for anyone commuting past the 5-mile-each-way mark or who wants to skip charging every single day. Run your own numbers on our range calculator.
Bigger wheels change the ride, not just the number
The Pro's 10-inch wheels roll over cracks, small potholes and expansion joints that the base S2's 8.5-inch wheels feel more sharply. Both use solid tires, so neither will go flat, but the larger wheel diameter on the Pro absorbs more of the road on its own before it reaches the rider. If your commute includes rougher pavement, the wheel size difference matters as much as the motor spec.
Weight limit: the base S2 is the bigger unknown here
The Pro's stated 220 lb max load gives you a number to plan around; the base S2 listing in our catalog does not clearly state one for this model. That does not mean the base S2 cannot handle a similar rider, only that the manufacturer has not published it here. If you are near or over 200 lb, check the current S2 listing for a stated weight limit before buying, or choose the Pro, where the number is already in writing. Use our weight limit calculator to see how close a given rider weight sits to any stated max.
Who should actually buy each one
The base S2 fits a lighter rider, a short flat commute under about 3 miles each way, and a buyer who wants Hiboy's fit and finish at the lowest entry price. The S2 Pro fits a heavier rider, a longer commute, rougher pavement, or anyone who would rather not think about range every single day. The extra $120 buys real range, real wheel size and a real stated weight limit, not just a badge.
How we chose
This comparison is built from manufacturer specifications listed in our catalog, not in-person testing. Recurring owner review themes for both models point to solid build quality at their respective price points, with the Pro's larger wheels most often cited as the noticeable upgrade.

Questions riders ask
Is the Hiboy S2 Pro worth the extra money over the base S2?
For most riders, yes. The Pro's 500W motor, 10-inch wheels and 25.6-mile claimed range (versus 350W, 8.5-inch wheels and 17 miles on the base S2) are real upgrades, not marketing. It also states a clear 220 lb max weight, which the base model's listing does not. If your commute is short and flat and you are on the lighter side, the base S2 still gets the job done for less.
Do both scooters use the same tires?
Both use solid tires, so neither will ever go flat, but the wheel size differs: 8.5 inches on the base S2 versus 10 inches on the S2 Pro. The larger wheel on the Pro rolls over cracks and small road imperfections more smoothly, which matters more the rougher your commute pavement is.
Which one is better for a heavier rider?
The S2 Pro, since it states a 220 lb max rider weight directly in its listing, giving you a number to plan around. The base S2's listing in our catalog does not clearly state a max load for this model, so a heavier rider has less certainty going in. Check the current base S2 listing for a stated weight limit before buying if you are near or over 200 lb.
How much further does the S2 Pro actually go in real riding?
Claimed range is 17 miles for the base S2 and 25.6 miles for the Pro, a claimed gap of about 8.6 miles. Apply the usual 60 to 80 percent real-world discount to both and the Pro still comes out meaningfully ahead in absolute miles, since the underlying claim itself is nearly 50 percent higher before any discount is applied.
Are the S2 and S2 Pro both UL 2272 certified?
Check the current listing for each model to confirm certification status, since it can be updated by the manufacturer. Buy any electric scooter that is UL 2272 listed for battery and electrical fire safety, and always charge it on a hard, uncluttered floor with the maker's charger rather than an unattended overnight setup near an exit.
