Here is a nice solution for everyone that rides a bike, which are most of my friends the live in NYC; I would implore them to give this a look once it becomes available to the general public. Not only is it a cool problem solver, it’s a very sleek looking bike.
The bike is designed by Lee Sang Hwa, Kim Jin Ho, and Yeo Min Gu.
Saddle Lock provides a way to quickly lock the rear wheel without the need for additional locking accessories. The seat post swings down around the main frame when a button is pushed. The saddle features a cut-away shape that allows it to sit over the rear wheel. A combination lock allows the release of a special alloy rotating lock that extends from one end of the saddle to the other, securing its connection to the wheel.
