S2
Origin
Hiboy is a Shenzhen-based Chinese e-mobility brand that launched in 2015 focusing on hoverboards before pivoting to e-scooters in 2018-2019. The S2 was Hiboy's breakthrough product — launched on Amazon US in late 2019 at $349 just as the post-Xiaomi-M365 budget e-scooter market exploded. Hiboy used aggressive Amazon advertising, sponsored YouTube reviews, and a US-warehoused fulfillment model (rare for a Chinese brand at that time) to dominate the sub-$400 segment for three years running. By 2022 the S2 was the #1 best-selling adult e-scooter on Amazon US in its price bracket. The success was based less on technical innovation and more on price-performance fit: 13.5 kg, foldable, dual brake, 25 km/h, Amazon-fast delivery, and competent enough for 90% of first-time buyers. The S2 became the 'first scooter' for millions of users worldwide.
Specifications
- Brakes
- E-ABS regenerative electronic anti-lock (motor-based) Front brake is electronic — no physical caliper. Mild regenerative effect, less aggressive than Segway G30. In emergencies, front E-ABS alone is inadequate. Open mechanical disc brake on rear wheel — actuated by hand lever on left grip. Effective in dry conditions but gets fouled by wet/mud (an open disc vs Segway G30's sealed drum). Brake pad replacements €5-10. Caliper alignment is a common DIY tweak after 1000+ km. Stopping distance is meaningfully longer than the Segway G30 (especially in wet). New riders should practice in a parking lot. The combination of 8.5" tires + open disc brake + lighter overall scooter means the S2 stops fast on dry pavement but struggles on wet cobblestone.
