GoTrax G4 vs Hiboy S2 Pro (Budget Commuter Showdown)

Choosing a budget commuter scooter can feel like splitting hairs. However, the GoTrax G4 and Hiboy S2 Pro sit in the sweet spot for price-conscious riders who still want reliable speed, decent range, and everyday durability. Consequently, this in-depth comparison distills official specs, real-world considerations, and commuter-centric advice so you can pick the scooter that actually fits your routine.

Key Takeaways

• Both are true budget commuters. Expect roughly 19–20 mph (30–32 km/h) top speed and a claimed range up to ~25 miles (40 km) under ideal conditions. Moreover, both deliver city pace without breaking the bank.
• Ride feel differs. The G4 uses 10″ pneumatic (air) tires for natural damping; meanwhile, the S2 Pro uses 10″ honeycomb (solid) tires plus dual rear shocks to offset their firmness.
• Security and app features diverge. The G4 includes a built-in cable lock and PIN-style digital code lock; by contrast, the S2 Pro offers the Hiboy S2 app with remote lock and configurable settings.
• Water readiness isn’t identical. The S2 Pro lists IPX4 (splash resistance). Conversely, the G4’s materials emphasize UL safety and general wet-weather guidance; therefore, treat it as light-rain only.
• Weight and portability are close. The G4 is about 37 lb (16.8 kg); the S2 Pro is 37.4 lb (17.0 kg). As a result, both fold quickly, yet neither is a featherweight for long stair carries.
• Warranty differs. The G4 lists 2 years on adult e-scooters, whereas the S2 Pro lists 1 year. Consequently, coverage length may influence daily riders.
• Quick picker:
  • Pick the G4 if you value air tires for smoother road feel, built-in physical security, and a longer warranty.
  • Pick the S2 Pro if you prefer maintenance-free tires, app locking and tuning, and factory rear suspension.

Quick Specs: Side-by-Side

Notes:

• Wh (watt-hours) = V × Ah; therefore, 36 V × 10.4 Ah ≈ 374 Wh, and 36 V × 11.6 Ah ≈ 418 Wh.
• The G4’s max load has appeared as 220 lb in older manuals and 264 lb on the current product page; accordingly, we note the discrepancy.

What Matters Most for Commuters

Range Reality

Manufacturers quote best-case numbers: warm temperatures, smooth pavement, and a light rider at moderate speed. In practice, colder weather, higher speeds, hills, and heavier loads diminish range. Although both scooters claim up to 25 miles (40 km), the Hiboy’s larger battery (~418 Wh) slightly improves endurance—provided you ride gently. Conversely, because air tires reduce vibration losses, the G4 can feel more efficient on rough asphalt at the same pace. Ultimately, your habits—steady cruising versus frequent bursts—affect results the most.

Ride Comfort

Comfort reduces fatigue and, consequently, mistakes. The G4’s pneumatic tires flex over cracks and seams, which softens chatter. By comparison, the S2 Pro’s honeycomb solids never puncture, yet they ride firmer; therefore, Hiboy adds dual rear shocks to help. Even so, the handlebar can still transmit more buzz than an all-air setup. On truly broken pavement, air tires win; on clean city lanes, both ride acceptably.

Braking & Safety

Both scooters use mechanical braking with electronic assistance. Consequently, lever feel, rotor condition, pad quality, and tire grip all matter. Because the S2 Pro pairs regen/e-brake with a disc and runs solid tires, stopping feel remains predictable but slightly harsher over ripples. Meanwhile, the G4’s air tires add compliance as you squeeze down. Either way, practice controlled stops from ~15 mph (25 km/h) and maintain pads and cables regularly.

Portability

At roughly 37 lb (≈17 kg), each is liftable for a flight of stairs or a quick hop onto a train. Nevertheless, neither is a casual shoulder-carry for long distances. Fortunately, the folding mechanisms are quick and intuitive. If you’ll carry daily, consider a shoulder strap; additionally, pre-scout indoor storage.

Weather Readiness

Both scooters are best for dry-to-lightly damp commutes. Specifically, the S2 Pro lists IPX4, meaning splash resistance. Conversely, the G4’s materials emphasize UL safety and light-rain guidance; consequently, avoid heavy downpours and deep puddles on either model. After damp rides, dry the scooter and store indoors to preserve components.

Maintenance

G4: You’ll check tire pressure (often 45–50 psi) and occasionally patch or replace a tube. In return, you get better grip and comfort.
S2 Pro: You skip flats thanks to solid tires, yet you may tighten hardware and inspect rear shocks periodically. On both scooters, keep the brake system adjusted, the folding latch snug, and the deck bolts checked. Consequently, minor upkeep prevents bigger issues.

Ride Quality & Handling

The G4 feels planted and forgiving on patched streets because air tires deform over bumps. Moreover, steering is neutral, with enough stability at ~20 mph (32 km/h) to inspire confidence. The S2 Pro tracks straight and feels slightly “livelier” up front since solids don’t deform as much; however, the rear shocks reduce kickback, especially on expansion joints. Therefore, if your commute features older tarmac, the G4’s compliance becomes noticeable. If, instead, you hate flats more than you love plushness, the S2 Pro’s no-flat promise plus rear shocks remains compelling.

Performance: Speed, Acceleration, Hills

Both scooters cite similar top speeds (G4 20 mph / 32 km/h, S2 Pro 19 mph / 30 km/h). Although acceleration to 15 mph (25 km/h) is not officially published, 500 W hub motors on 36 V systems usually deliver brisk city starts—especially on flat ground. For hills, Hiboy lists 15° capability; nevertheless, angle marketing can be optimistic. Consequently, technique helps: start with momentum, keep knees flexed, and avoid stopping mid-slope. Heavier riders should prefer the G4’s higher published payload ceiling.

Battery, Charging & Longevity

• Chemistry & capacity: Both use 36 V lithium-ion packs. Notably, the S2 Pro’s 11.6 Ah (~418 Wh) offers ~12% more energy than the G4’s 10.4 Ah (~374 Wh).
• Charging: The G4 typically uses a 42 V / 2 A charger; its manual quotes ~3–4.5 hours. Meanwhile, the S2 Pro lists a wide 100–240 V adapter input; thus, charge times may vary by charger version.
• Care tips: Store between 10–25°C (50–77°F) when possible; furthermore, avoid full discharges and do not leave the scooter in hot sun or a cold trunk. For longevity, use 20–80% for daily cycling and ~50–60% for multi-week storage.

Comfort, Portability & Build

• Decks: The S2 Pro deck ~17.7″ × 6.1″ (450 × 155 mm) feels standard for shoulder-width stance. Although G4’s brand materials don’t publish exact deck size, both feel adequate for urban riding.
• Fold & carry: Each folds quickly with a front-latch mechanism. Crucially, secure the clasp fully; a loose latch is the most common source of stem play.
• Frames & finishes: Both use aluminum alloys. Consequently, expect normal commuter wear on bar ends, kickstand, and fenders over time; periodic tightening reduces rattles.

Features & App Experience

• GoTrax G4: Clear LCD, cruise control, and notably two security layers—a built-in cable/tiller lock and a three-digit display lock code. As a result, casual misuse becomes less likely.
• Hiboy S2 Pro: The Hiboy S2 app lets you lock/unlock, toggle lights, switch modes, and adjust limits. Additionally, cruise control and a three-light system (head/tail/sidelights) aid visibility.

Reliability, Warranty & Support

• G4: 2-year coverage is strong in this price tier. Accordingly, keep proof of purchase and document issues with photos or video.
• S2 Pro: 1-year coverage remains standard for the class. Nevertheless, Hiboy provides troubleshooting, manuals, and app updates.
• Wear parts: Expect brake pads, tires, and possibly rear shock bushings (S2 Pro) to be typical consumables. Sensible speeds, smooth braking, and indoor storage, therefore, extend service life.

Costs & Value Over Time (TCO)

Electric scooters are exceptionally cheap to “fuel.” Consequently, energy often represents the smallest ownership cost.

• Energy use assumption: commuter scooters typically consume 15–25 Wh/mi (9–16 Wh/km), depending on speed, terrain, and rider mass.
• Electricity price example: $0.15 per kWh (adjust to your local rate).

Energy cost per 100 miles (160 km):

• At 15 Wh/mi → 1.5 kWh × $0.15 ≈ $0.23
• At 20 Wh/mi → 2.0 kWh × $0.15 ≈ $0.30
• At 25 Wh/mi → 2.5 kWh × $0.15 ≈ $0.38

Even at the high end, the figure stays well under fifty cents per 100 miles. Consequently, the bigger TCO drivers are tires, brakes, and time. Solids (S2 Pro) reduce flat-related downtime; conversely, pneumatics (G4) save wrists and improve grip, potentially reducing crash-related costs. Balance according to your roads.

Use-Case Matchups

Short, Flat City Hops

Either scooter works. Nevertheless, the S2 Pro’s no-flat tires and app lock make it a fuss-free errand runner.

Hilly Suburbs

Power is similar; however, the G4’s higher published payload and air tires help on imperfect pavement where traction matters.

Heavier Rider (≈100–120 kg)

The G4 is the safer bet given its up-to-264 lb (120 kg) published limit on the current product page. Consequently, taller or heavier riders may feel less constrained.

Winter or Frequent Rain

Neither is built for storms. Even so, the S2 Pro’s IPX4 rating is explicit, while the G4 should be treated as light-rain only. Therefore, ride slower, increase following distance, and dry the scooter afterward.

Apartment Carry or Train Hops

This is largely a toss-up. Since both weigh ~37 lb, choose based on features (G4 security vs S2 app). If you climb many stairs daily, consider a lighter model overall.

Head-to-Head Verdict

Below is a simple decision matrix (weights in parentheses). We score 1–10 per scooter based on official specs and typical class performance. Importantly, justifications emphasize commuter impact.

Overall verdict: You can’t go wrong with either scooter for sub-$600 commuting. If your streets are cracked, patched, or brick, the G4’s air tires and longer warranty tip the scales. Alternatively, if you hate flats and value app control, the S2 Pro is an easy keeper—especially when discounted.
