Why is the Birdy so expensive ?
The Birdy frame is manufactured by hand with considerable precision in a labour intensive process (check out the beautiful welding lines on the bike). Many measurements and adjustments are required during the manufacturing process. In fact the frame sections are re-aligned by hand three times during the manufacturing process to ensure the frame meets rigid requirements for folding: Once after initial welding, once after heat treatment and then finally after powder coating as a complete bike. All of these alignments are done by hand. The frame design of the Birdy might look simple and straight forward but it is much more complex than meets the eye. For example the front and rear swingarms are perfectly in line when the bike is unfolded but they go out of line when the bike is folded. The very unique features of the Birdy (suspension that is incorporated into the folding mechanism, a jointless main frame and low weight) demand a complex frame design and complex manufacturing process.
