Most of the existing foldable electric bicycles on the market are two fold, with a smaller volume and more convenient portability compared to ordinary electric bicycles. However, when the tube in the frame is too long, it still occupies more space. Therefore, how to achieve a more convenient and compact car model has become a topic that Space Cardan has been thinking and researching.

After several years of research, the manufacturer of Tianxi electric vehicles has invented a patent for a three fold bicycle and applied it to folding electric vehicles. The main purpose is to reduce the volume, save space, and make travel more convenient. It does not affect the length of the central tube or the size of the vehicle model at all, only making it easier for electric bicycles to store and travel.

Space Cardan manufacturer adheres to the original intention and production philosophy of "customer first, quality first" from bicycle transmission shafts to the later production and research and development of electric bicycles,

Gradually becoming a trustworthy electric bicycle manufacturer in the minds of customers.
