The HiBoy S2 Pro began its swift ascent to bestseller status around late 2020 and early 2021, a period when electric scooter demand was skyrocketing worldwide—particularly on Amazon and other major e-commerce platforms. While HiBoy was not entirely unknown (they had been producing personal electric vehicles for a few years), it was the S2 Pro model that truly thrust the brand into mainstream recognition. By mid-2021, it had become one of Amazon's top-ranked electric scooters in the budget-to-midrange category, often edging out better-known competitors like Segway-Ninebot and Xiaomi.
Below is our comprehensive deep-dive into why the S2 Pro took off so quickly—along with a nuanced look at its specifications, performance, real-world user feedback, and important considerations such as long-term reliability and safety.

The HiBoy S2 Pro is a foldable electric scooter designed primarily for urban commuting. Priced around $400–$500 (sometimes lower when discounted), it balances everyday performance with commuter-friendly conveniences like solid tires, decent range, smartphone connectivity, and optional seat compatibility.

The Appeal: Why Did It Get So Popular?
1. Aggressive Pricing
With periodic discounts dropping it to $400–$450, the S2 Pro undercuts many competitors with similar performance.
2. Feature-Rich for the Price
The combination of rear suspension, app connectivity, cruise control, integrated lights, and a high-mounted charging port make it feel more premium than the price suggests.
3. Solid Tires = Zero Flats
Budget scooters often use pneumatic tires that risk flats. The S2 Pro's solid honeycomb tires appeal to riders wanting minimal upkeep.
4. High User Ratings and Word-of-Mouth
Thousands of positive reviews on Amazon and other platforms—plus strong word-of-mouth on Reddit and YouTube—fueled its rapid rise to "bestseller" status.
Known Issues and Limitations
1. Ride Comfort and Solid Tires
Without front suspension, the front wheel transmits every bump directly to the stem. Solid rubber tires can have reduced traction in rain.
2. Loose Screws and Stem Wobble
Various bolts can loosen over time due to vibration. Owners report needing to tighten them regularly.
3. Battery and Electronics
The battery is only covered for 6 months, shorter than the 1-year coverage for the rest of the scooter.
Comparing to Higher-End Alternatives
While the S2 Pro appeals strongly to budget-minded consumers, some riders might consider spending more for an upgraded scooter like Levy, Segway Ninebot Max, Xiaomi Pro, or Apollo models for better build quality, pneumatic tires, better suspension, and longer warranties.
Value for Money: Is the S2 Pro Worth It?
Despite its known drawbacks, the HiBoy S2 Pro remains one of the most popular and best-value electric scooters for adults in the sub-$500 range. The combination of 19 mph top speed, 15–25 mile range, dual brakes, rear suspension, no-flat 10-inch tires, and app connectivity is hard to beat.
Who Should Buy It?
- Students and Urban Commuters on a budget needing a daily ride of ~5–10 miles.
- Casual Riders who want a scooter for short errands or recreational outings.
- First-Time Scooter Owners looking for an affordable entry point.
Who Should Skip It?
- Heavier Riders approaching or exceeding the 220 lb limit.
- Those Riding on Very Rough Pavement or in consistently wet weather.
- Buyers Seeking a Long-Term, "Bulletproof" Scooter willing to spend $800–$1000+ for premium construction.
Final Thoughts
The HiBoy S2 Pro earned its spot as one of the fastest-selling electric scooters largely due to aggressive pricing, respectable performance, and a feature set that competes well above its budget category. While it rocketed to Amazon's best-seller lists around 2020–2021, popularity does not automatically guarantee perfection. There are clear trade-offs in build quality and long-term reliability that prospective buyers should understand.
Ultimately, the S2 Pro's meteoric rise from a lesser-known Chinese import to a major best-seller underscores both the huge demand for affordable e-mobility options and the importance of weighing real-world feedback.
