Why is BIRDY valuable?

Though seems quite simple, BIRDY contains many complicated and refined design.
For example, the vertical folding design requires extremely precise adjustment.

This one-of-a-kind characteristic requires accurate computation, superior manufacturing techonology and strict quality control while processing design and mass production. Unlike most of the folding bikes with folding hinges on their main frame, which could be produced by machine, BIRDY needs to be handmade by professional workers.

Why is BIRDY special?

BIRDY is a real "folding bike" which you can easily fold/unfold within 15 seconds without using any tool. It is extremely compact after being folded without any parts separated apart from the main frame.
This is why BIRDY becomes one of the most outstanding commuting folding bike. In spite of the time and location, it is always convenient and easy to fold/unfold.
Unlike most of the folding bikes which have folding hinges on their main frame and thus make the main frame relatively fragile especially during high-speed riding, BIRDY is proud of its resistant and durable main frame, which adequately integrated with the folding structure and suspension system.
The weight and the mobility capability are always the main concern for folding bike riders. BIRDY is functioned not only as a commuting bike but also a superior traveling bike. With the newly-developed rear carrier, which could perfectly be folded without any additional effort, BIRDY can carry luggage up to 25 kilograms.
