3. Manufacturing Process of Little Kids Mountain Bike

Raw Material Inspection
All magnesium alloy and component batches undergo spectrometry and physical checks per ISO 9001/ISO 4210 to ensure high strength and low impurities.
Frame Molding & CNC Machining
Advanced die-casting molding creates seamless, hollow-tube frames. Key stress points (head tube, dropouts) undergo precision multi-axis CNC machining for tolerance control within 0.08mm.
Welding & Surface Finishing
TIG/laser welding joins frame sections. Double powder-coating and anti-corrosion primer ensure a durable, UV-resistant finish.
Component Integration
Installation of Shimano-compatible 7-speed system, disc brake calipers, child-ergonomic grips & saddle.
Assembly & Testing
100% functional testing—brake force, gear shifting, and ISO 4210 impact/roll tests. Each bike is road-tested and serialized for traceability.
Packing & Logistics
Shockproof packing and RFID batch tracking ensures safe global delivery.

FAQ – Little Kids Mountain Bike Technical Expert Panel

1. What is the difference between magnesium alloy and aluminum alloy frames?: Magnesium alloy frames are approximately 34% lighter than standard aluminum, deliver better vibration damping, and superior corrosion resistance after proper coating. This results in a lighter kids mountain bike that’s easier and safer for kids to control.
2. What does “EN 14765” and “ISO 4210” compliance mean for child safety?: Both are international standards for cycle safety and performance. They ensure the little kids mountain bike passes demanded impact, fatigue, and brake force tests—vital for end-user safety.
3. How is disc brake performance verified?: Each bike undergoes EN 14766 braking force testing (dry/wet). A good system achieves a stopping distance under 3.5m from 20km/h on flat asphalt.
4. What is CNC machining and why is it important?: CNC (Computer Numerical Control) machining executes precision cuts for key stress points (dropouts, head tube), guaranteeing assembly tolerances below 0.1mm—vital for a safe ride and long bike life.
5. What are typical frame lifespan and anti-corrosion features?: With correct anti-rust coating (ASTM B117 240h rating), magnesium frames last 7-10 years in active use.
6. Which age and height is a 20-inch little kids mountain bike suitable for?: Suits children 118–140cm tall (typically ages 7–12), offering optimal standover height and control for growing legs and arms.
7. What support is provided after purchase?: All little kids mountain bike models include lifetime online tech and spare parts service, video guides for assembly, and full warranty cover.
