wholesale kids bike for 9-12 age kids Child Sport Mountain Bicycle With Shock Absorber

Kids’ bikes are having a moment. Parents want safety and real trail capability; retailers want durable stock that doesn’t boomerang back for repairs. From Hebei’s manufacturing belt—Dongmiao Industrial Zone, Hegumiao Town, Pingxiang County, Xingtai City—this model lands squarely on that sweet spot: a hardtail youth MTB with a spring fork and dual disc brakes. To be honest, that combo used to be rare at this price tier; now it’s becoming the baseline.

Who it fits and where it thrives

Sized in 18/20/22 inches, it targets ages 7–16; in real shops, the 20 and 22 inch sizes cover most 9–12-year-olds. Commutes to school, weekend park loops, after‑school MTB clubs—this bike is built for that mix of pavement and light trail. Many customers say their kids “graduate” to gears and discs right around this age, and the confidence bump is obvious.

Key specifications at a glance

Manufacturing and testing workflow

• Materials: high‑carbon steel tubes; surface pre‑treatment (phosphate) and electrostatic powder coat.
• Methods: jigged welding, alignment checks, fork spring preload set for youth weight range, wheel truing.
• Quality tests: frame fatigue to ≥100,000 cycles (aligned with ISO 4210 practice), brake performance per CPSC 16 CFR Part 1512; 72‑hour ASTM B117 salt‑spray on small parts.
• Service life: ≈5–7 years with routine maintenance; consumables (pads, tires, chain) on normal replacement cycles.

In a recent in‑house run (20" setup), dry stopping from 15 km/h averaged ≈3.6 m; wet surface ≈5.4 m. Not lab gospel, but a solid indicator.

Advantages retailers mention

Dual discs at this tier reduce warranty headaches; the spring fork takes the edge off curbs and gravel. Paint holds up—the powder coat is surprisingly resilient against the usual bike‑rack battles. Parents like the color options; shops like that cables and pads are standard and easy to source.

Customization for B2B orders

OEM logo and decals, gearing choice (SS/6/7‑speed), tires (street/trail), saddles, reflectors per destination (CPSC or EN), carton art and multilingual manuals. ISTA‑2A packaging drop tests available on request.

Vendor comparison (quick buyer’s view)

Mini case study

A coastal rental park took 180 units (20" & 22"). After a season of salt air and sand, returns were below 2%. They credited the powder coat and straightforward mechanical discs. Parents, anecdotally, praised the stable handling on boardwalk seams—small detail, big trust.

Compliance and documentation

Factory offers ISO 9001‑based quality management. Bikes can be produced to comply with CPSC 16 CFR Part 1512 (US) and EN ISO 4210 series (EU). If you need destination‑specific reflectors, torque specs, or batch test summaries, request them upfront—it speeds customs.

wholesale kids bike for 9-12 age kids Child Sport Mountain Bicycle With Shock Absorber orders ship assembled to ≈85% with tools included; final setup (handlebar, front wheel, pedals, brakes check) is standard shop work, about 20 minutes per unit. Honestly, that matters in peak season.
