FAQ:

Q: Which is the best u-lock for a bicycle?

A: The best mini U-lock. If you’re looking for the highest level of security from a lock that is big enough to fit around a wide range of objects, the New York Standard, the Brute STD and the Granit X-Plus 540 are the best bicycle U-locks available today.

Q: How big of a you lock do I need for my bike?

A: Thicker shackles are more secure! U-locks with diameters of less than 13 mm could be susceptible to attacks by medium sized bolt cutters which some opportunist thieves do use. Better u-locks, with diameters of between 13 and 15 mm are unlikely to be defeated by anything but the biggest bolt cutters which most casual bike thieves just won’t have.

Q: Are there any bike locks that are unbreakable?

A: The best bike bike locks are secure, virtually unbreakable and simple to use. Unfortunately, the two most popular types are flimsy cables and cheap U-locks.

Q: Is it safe to use a cable lock on a bike?

A: The cable is very light (and cheap). So you can secure the most valuable parts of your bike without adding too much weight (or cost) to your u-lock. In reality these cable locks offer very little practical protection.
