TECHNOLOGIES

All our technologies are developed to achieve certain special application purposes of a product. Simply say, technology is born from riders' demands. Based on our different product designs, there are different purposes and guiding ideas behind them. Therefore, our engineering team has worked out proper and practical technologies for tooling, and manufacturing processes to make our products unique and stable.

PROCESS & PRODUCTION

Quality Control

Product quality is always originated from the raw materials to the complete production process.
The QC system functions as a solution to pick out inferior products and make sure all the goods to customers are flawless.
In our company's philosophy, the most economic solution is always to nip any potential risks in the bud.
So we set out and execute a strict QC system to shut down any chances of the inferiority complaints arising from the market relentlessly.

Testings

Testing is another important part of a complete and mature factory. All technologies and ideas needed to be proved and supported by objective testing numbers.
Even during bulk production, testings also play the role of an alarm and work as a supplement to the QC system.
So we always insist on two testing systems to support our engineering team and production team.
