Losing your bike is not a fun experience. Unfortunately, it could happen if you are not too careful. Bike thieves are going to have a difficult time stealing a YERKA bike though. It has an integrated locking system that lets you secure your bike to a pole fast. Thieves will have to cut through the main structure to take your bicycle, which is not something they are interested in doing.
You also get anti-theft nuts for your wheels. The developers are also working to add Bluetooth to the YERKA bike. The above video shows how this bike works. You can find it on Indiegogo.
