To ensure safety and protect the rights and interests of consumers, ebikes need to pass some certifications including UN38.3, UL, FCC, ROHS, CE, etc. Amongst them, CE certification is a mandatory standard for products sold in the European market. The CE certification means the products have been assessed to meet high safety, health, and environmental protection requirements. When ebikes are transported to the EU, the customs will check the CE certification along with the products for customs clearance. All those uploaded certificates were provided to us in electronic PDF form by the manufacturers . Analytical reports of testing those bikes could be provided upon request and after ordering those bikes through us.
