When did the HiBoy S2 Pro become the fastest selling electric scooter?

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. The reasons were simple yet powerful: a compelling price point and a well-rounded spec sheet that promised higher speed, decent range, and practical commuter features at a fraction of what many rival scooters cost.

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.

HiBoy S2 Pro

Introduction and Overview

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. These features have propelled it to become one of the most popular budget scooters on Amazon and other major online marketplaces.

But how does it hold up under scrutiny? Is the S2 Pro really as good of a deal as its initial hype suggests? Below, we’ll explore all aspects of the scooter: from its raw specs and features to common user complaints, warranty experiences, and why some riders might ultimately choose alternative brands with stronger build quality.

Specifications and Features

1. Frame and Design

• Material: Aluminum alloy

• Weight: ~36–37 lbs (≈16.5 kg)

• Max Load: 220 lbs (100 kg)

• Folded Dimensions: 45.3 × 16.5 × 19.3 in (approx.)

• IP Rating: IPX4 (can handle light splashes, but not heavy rain)

The S2 Pro sports a sturdy aluminum frame with a wide standing deck that can optionally accommodate a detachable seat. It folds down via a latch at the stem, locking compactly for transport or storage.

2. Motor and Top Speed

• Nominal Power: 500 W brushless hub

• Peak Output: 750 W

• Top Speed: ~19 mph (30 km/h)

Owners often report hitting 19–20 mph on flat ground, which is plenty for city commutes or campus rides.

3. Battery and Range

• Battery Pack: 36 V, 11.6 Ah (≈417 Wh)

• Advertised Range: Up to 25 miles under ideal conditions

• Real-World Range: Typically 15–20 miles (depending on rider weight, terrain, speed mode)

• Charging Time: ~4–6 hours

A regenerative braking system helps recapture a little energy, though it’s not a major contributor to total range. The battery is built into the deck (non-removable), and owners should charge at least once every 2–3 months if the scooter is in storage to avoid over-discharge.

4. Tires and Suspension

• Tires: 10-inch honeycomb solid rubber (no flats)

• Suspension: Dual rear spring shock absorbers

• Front Suspension? None

The large, solid tires won’t ever go flat but transmit more road vibration than pneumatic tires, especially in the front. Dual rear springs help mitigate bumps on moderate terrain, but very rough roads can still deliver jolts through the un-suspended front wheel.

5. Brakes and Lighting

• Braking System: Mechanical rear disc brake + electronic (regenerative) front brake

• Lighting: Integrated LED headlight, tail/brake light, blue side deck lights

• Horn: Electronic beeper on handlebar

The dual braking setup is quite effective: the e-brake alone can handle gentle slowing, while the rear disc provides a stronger stop if needed.

6. Controls and Smartphone App

• Display: Central LED showing speed, battery, mode

• App Connectivity: Hiboy S2 app (iOS/Android) via Bluetooth

• Features: Cruise control, lock/unlock scooter, ride statistics, speed-mode customization

Riders can switch between Eco (slower, battery-saving) and Sport (full power) modes. Cruise control automatically activates after maintaining the same speed for ~5 seconds.

7. Optional Seat

• Hiboy sells a matching seat that bolts onto the deck, making longer rides more comfortable. Many reviewers who bought the seat version say it helps reduce fatigue on extended commutes.

Performance in Real-World Conditions

• Acceleration and Speed: The 500 W motor offers surprisingly peppy acceleration for a scooter in this price class. Heavier riders still report reaching ~15–18 mph on modest inclines.

• Range: While you’ll see the typical “advertised vs. reality” gap, the S2 Pro commonly manages 15–20 miles per charge under normal city use. Lighter riders or those sticking to ~10–12 mph can nudge closer to 25 miles, but expect that only on smooth, flat terrain.

• Hill Climbing: Rated for ~15% grades, the scooter can climb moderate hills at reduced speed but may bog down on very steep inclines if near the 220 lb load limit.

• Ride Quality: On smooth pavement, it’s a stable, comfortable ride. When roads get bumpy or potholed, the lack of front suspension becomes noticeable, and the solid tires can feel harsh. Slowing down on rough stretches is advisable.

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. It delivers “19 mph and 20+ miles range” at half the cost of some mid-range models.

2. Feature-Rich for the Price

The combination of rear suspension, app connectivity, cruise control, integrated lights, and a high-mounted charging port (to protect from water splash) make it feel more premium than the price suggests.

3. Solid Tires = Zero Flats

Budget scooters often use pneumatic tires that risk flats, adding maintenance costs. 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.

All these factors helped the HiBoy S2 Pro dominate sales charts from 2021 onward, catching many established brands off guard in the budget commuter segment.

Real-World User Feedback and Common Praises

• Overall Satisfaction: Many owners rate it 4+ stars out of 5, praising its stability, app features, and “fun yet practical” vibe. Users regularly confirm achieving 19 mph and 15–20 miles per charge without major issues in the first few months of use.

• Comfort: On decent roads, the scooter feels smooth. The deck is roomy, the handlebars are a comfortable width, and the rear springs absorb typical city bumps well enough.

• Maintenance: After initial assembly (handlebar screws, etc.), owners say it feels solid out of the box. Some do a quick brake calibration or minor alignment. Adding threadlocker (Loctite) to critical bolts upfront is highly recommended to prevent loosening later.

• Seat Attachment: Those who add the optional seat report being able to ride the full battery range without much fatigue, transforming the scooter into a pseudo-moped for city travel.

A telling quote from one Amazon reviewer:

“I wasn’t expecting much for $450, but it’s surprisingly fast and well-built. I cruise at ~18 mph comfortably. It’s the perfect solution for my 5-mile commute.”

Cracks Beneath the Surface: Known Issues and Limitations

Despite its popularity, the HiBoy S2 Pro is not without flaws. Below are the most frequently cited concerns from owners’ long-term experiences.

1. Ride Comfort and Solid Tires

• Harsh on Rough Terrain: Without front suspension, the front wheel transmits every bump directly to the stem. While the rear dual shock helps, it cannot compensate fully for big potholes or uneven pavement.

• Slippery When Wet: Solid rubber tires can have reduced traction in rain or on wet surfaces. Numerous riders caution that “any moisture makes it prone to slipping,” so caution is advised in damp conditions.

2. Loose Screws and Stem Wobble

• Periodic Tightening Required: Various bolts (especially around the folding mechanism and stem) can loosen over time due to vibration. Owners report needing to tighten them every few weeks or monthly, using threadlocker to keep them secure.

• Potential Stem Wobble: If the stem bolts become loose and aren’t addressed, the handlebar can develop play or, in rare cases, cause cracks in the weld.

3. Folding Latch Failures

• Rare But Serious: A small number of users experienced the folding latch popping open mid-ride, causing the stem to collapse forward. This is obviously dangerous. It’s crucial to ensure the latch fully locks and the safety pin is properly engaged.

4. Battery and Electronics

• Battery Warranty: The battery is only covered for 6 months, shorter than the 1-year coverage for the rest of the scooter. Some riders who left the scooter unused for months found the battery “bricked” from deep discharge and had to pay out-of-pocket for a replacement.

• Controller/Throttle Glitches: A handful of owners reported sudden power failures or a broken throttle lever. Though not extremely common, such defects can be frustrating if they occur out of warranty.

5. Long-Term Durability Concerns

• Stem/Neck Weld Breaks: The most alarming failures have been a few reported cases of the neck weld snapping after many miles or heavy abuse (riding with a loose stem, going over large bumps, or exceeding the weight limit). While rare, it underscores that the S2 Pro is not overengineered for high-impact use.

Build Quality and Long-Term Reliability

Overall, the HiBoy S2 Pro is regarded as one of the better-built budget scooters—but it’s still a “budget” product. Users who baby their scooter, keep bolts tight, and ride on relatively smooth roads often enjoy a year or more of trouble-free commuting. Others who subject it to heavier stress can encounter structural or electrical problems more quickly.

• Motor and Drivetrain: Generally robust, with few reports of motor burnout.

• Frame and Folding Joint: Adequate if maintained, but susceptible to metal fatigue if the stem is allowed to wobble.

• Battery Longevity: Likely to remain above ~80% capacity through the first year. Proper storage and charging habits are essential for a healthy battery.

• Maintenance Tip: Many high-mileage riders say routine bolt checks and conservative riding (slowing down for bumps) go a long way toward extending the scooter’s lifespan.

Some owners adopt the viewpoint that even if the S2 Pro only lasts a year or two of daily use, the cost savings (versus a more expensive brand) still justify the purchase. Others prefer to invest in a premium model with sturdier components and a longer warranty.

Customer Service and Warranty Experiences

• Warranty Details:

• 1-year coverage on the scooter’s major components

• 6-month coverage on the battery pack

• Wear-and-tear items like brake pads typically excluded

• Mixed Reviews:

• Positive Cases: Some owners who suffered serious failures (like a snapped neck weld) slightly after the 1-year mark report that HiBoy replaced their scooters at no cost, “no questions asked.”

• Negative Cases: Others with battery failures around the 6–12 month mark felt HiBoy adhered too strictly to the 6-month limit, forcing them to buy a new battery at \$150–\$180.

HiBoy does have U.S. service centers and fairly responsive email/phone support compared to many other direct-import brands. However, experiences vary. If you’re within warranty and have a clear-cut defect, service tends to be smooth. Outside that window, the cost of repair parts can approach a substantial fraction of a new scooter.

Safety Concerns and Precautions

1. Frame Integrity and Folding Latch

• Always ensure the stem is locked securely; never ride if there’s noticeable wobble.

• Periodically inspect welds for cracks, especially near the folding joint.

2. Braking on Slick Surfaces

• Solid tires + moderate e-brake can cause wheel slip in wet conditions. Ride slowly and brake gently if the ground is damp.

3. Protective Gear

• With a ~19 mph top speed, wearing at least a helmet is strongly recommended. Elbow/knee pads are advisable for beginners or if riding on uneven roads.

4. Battery Safety

• The battery is not UL 2272 certified (common for many budget scooters). Use the original charger, avoid overcharging, and keep the scooter out of extreme heat/cold.

No major recalls have been issued for the S2 Pro, and catastrophic issues (like battery fires) have not surfaced widely. Most safety problems stem from mechanical oversights (loose bolts, improperly latched stem) or user behavior (going too fast on bumpy roads, riding in heavy rain, ignoring weight limits).

Comparing the HiBoy S2 Pro 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. Here’s why:

1. Build Quality and QA

• Brands like Levy (assembled/tested in the U.S.) or Segway-Ninebot often have tighter quality control, reducing the risk of weld failures or defective electronics.

2. Pneumatic Tires and Better Suspension

• More premium scooters tend to have front/rear air tires—or front suspension—to better handle rough terrain and wet conditions.

3. Longer Warranties and Stronger Support

• U.S.-based brands or international giants (like Segway-Ninebot) might offer 12–24 months on the battery and have well-established repair networks.

However, these upgrades typically come at a significantly higher price ($700–$1000+). If your needs are modest—and you’re careful with maintenance—the S2 Pro may still be the best bang for your buck.

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

• App connectivity

…all at a low price, is hard to beat. Many first-time e-scooter buyers find the S2 Pro hits a “sweet spot” of performance and cost. Even with potential maintenance quirks, the overall experience tends to exceed expectations for a budget model.

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 into personal electric mobility.

Who Should Skip It?

• Heavier Riders approaching or exceeding the 220 lb limit, especially if facing frequent hills.

• Those Riding on Very Rough Pavement or in consistently wet weather. A model with front suspension or pneumatic tires might be safer and more comfortable.

• Buyers Seeking a Long-Term, “Bulletproof” Scooter who are willing to spend $800–$1000+ for premium construction and extended warranties.

Final Thoughts and Conclusion

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—overtaking many established competitors—popularity does not automatically guarantee perfection. There are clear trade-offs in build quality and long-term reliability that prospective buyers should understand.

That said, in purely practical terms, the S2 Pro delivers a lot of scooter for the money. If you maintain it diligently (tightening bolts, checking the folding mechanism, and riding sensibly), it can be a fun and convenient commuter tool. For many owners, the cost savings and ease of use outweigh the occasional mechanical quirks. If safety, higher-level quality assurance, or extended warranty coverage is your top priority, looking at slightly pricier alternatives (like Levy or Segway Ninebot Max) might bring extra peace of mind.

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. Do your research, ride safely, and if you choose the HiBoy S2 Pro, you’ll likely understand why it’s so popular—and perhaps find it the perfect match for your budget and commuting needs.
