YERKA fixed gear bike with frame lock and bluetooth.
Security, Performance and
Comfort achieved together
into one sleek design.
This bike was definitely engineered after the motto „form follows function“ as the bike itselfs works as the lock. Spin the frame around an object and lock it with your seatpost. That’s how this invention works. Unfortunately this ride is not available, yet. Nevertheless it simplifies cycling massively by implementing one function to the regular fixie frame.
