stem lock / lock

stem lock

This bicycle lock is composed of a key and a aheadset stem which is matched with the key.We make the aheadset Stem a part of the bicycle as a‘lock’.So when you are riding your bike you have to insert the key in the aheadset stem to join the aheadset stem and fork.And when the bicycle is not available, you just take away the key. Besides, since without key, the aheadset stem and the handle bar can rotate on the fork. We can turn the handle bar 90 degree to save the space.
The key is delicate and firm, symmetrical on the central axis. The metal ring on the key can fasten the nick in the aheadset stem to prevent the key from dropping.
