Never worry about rusty keys, stolen keys or too many keys. A 5-digit resettable combination lock mechanism allows up to 100,000 possible codes, making the bike lock unbreakable. The bicycle chain lock can be easily set or reset with a personal number combination. This bicycle lock chain makes your life more convenient.
