chosen: U-locks and chain locks are the best types of bike locks for providing the greatest protection against theft. U-locks provide an extremely strong and secure lock, as they loop around the frame and the wheel of the bike. Chain locks can also be very effective, as they create a long and complex lock that would be difficult to cut through.
