What are you deciding?
Using the guides and contacting the team
Use these guides to work through a choice, compare offers or prepare questions for a supplier. Product pages describe the vehicle; the general FAQ covers payment, delivery and support policies.
Approved project specifications, manufacturer documents, applicable authority requirements and unit-linked inspection records take priority over general website guidance.
Hangzhou team and Suizhou factory
Zhejiang Jingyan Technology Co., Ltd. was established in Hangzhou in 2016. KEEYAK is its outward-facing brand. The 345 m² Hangzhou office houses the sales and technical support team.
The company’s Suizhou manufacturing factory was established in 2009 and covers 110,000 m². The factory’s history and area are separate from the Hangzhou company’s founding date and office area.
These details are supplied by the company. A verification of the Hangzhou office does not verify the Suizhou factory area. For a specific order, confirm the seller, manufacturing site and unit-linked documents separately.
