Core Services

CKD Knock-Down Supply and OEM Branding

Two services that most parts traders cannot offer: a matched component set for your local assembly line, and private-label branding across parts, packaging and manuals.

Full Compliance Documents

CE, RoHS, UL, UN38.3 and MSDS files are ready for customs clearance and platform listing in your market.

Flexible MOQ & Trial Orders

Small trial orders are supported so repair wholesalers and conversion shops can test the market before scaling up.

Mixed Container Loading

Combine different parts and models in one container to match your sell-through and reduce inventory pressure.

Dongguan Supply Chain

Based in Dongguan next to Shenzhen, with dense Pearl River Delta sourcing and short drayage to major ports.

Refundable Sample Cost

Sample charges can be refunded from your following bulk order, lowering the cost of supplier evaluation.

12-Month Core Warranty

Hub motors and controllers carry a 12-month warranty; wear parts are excluded and quoted separately.

Buyer Feedback

What Our Overseas Partners Say

We import conversion kits for the German market and the documentation set made customs clearance straightforward. The mixed container option lets us stock kits, displays and harnesses together instead of committing to a full container of one item.
