Compact Folding Bike Lock
Security rating 4. The lock cylinder employs advanced anti-theft Swiss technology. The slim lock profile attaches to the frame or can be easily slipped into a pocket or purse. The key is small and complex which makes it difficult to copy. A highly technical heat process is applied to specially hardened steel to help prevents the average crook from snipping it lose. The outer coating is rugged but is coated to protect the bike's paint.
