ABSTRACT:
A locking device for securing a bicycle to a pole, post, bar or other stanchion is provided. The lock includes a shackle, formed from a bar of metal stock bent around itself forming a pair of parallel legs connected at one end open ended at the other end. The parallel legs are bent in a U-shape to form a shackle with legs connected at one end and open at the other. A cross bar, fitted with a locking mechanism includes holes adapted to receive the two open ends of the shackle. With each end of the shackle leg slated for forming a latch slot, a double tongue sliding latch supported in the cross bar engages the latch slots for locking the cross bar to the shackle.
