For great theft protection while you are in class or headed into work, the UltraCycle U-lock has your back..or in this case.. your bike. The stylish user friendly lock, is ideal to stash in your bag or on your belt. This is a drill, pick and cut resistant hardened steel shackle, and a non-damaging rubber coated finish. Perfect for any situation. A lock you know you can trust.
U-locks are more secure than most other kinds of locking mechanism because they are more resistant to cutting with high-leverage hand tools such as bolt cutters. However, most are still vulnerable to at least one type of exploit. For instance, if there is enough space for a thief to fit a jack into the U, the jack can produce enough leverage to break the lock. Another common brute force method to break open U-locks is to use a long length (perhaps 2 meter) of pipe to twist the lock open (although this method is more commonly used to defeat chain and cable locks). Like all locks, U-Locks are vulnerable to power tools such as portable angle grinders. A quality U-lock will advertise the material's hardness (relative resistance to grinding), its resistance to prying (expressed in tonnes, or pounds, for example, one might resist to 5 tonnes, which exceeds the 2-tonne capacity of a common car jack), as well as resistance to drilling into the keyhole itself. A U-lock is a rigid metal ring in the shape of the letter U. The U part of the lock attaches to a crossbar section, and for this reason they are also called D-locks. To lock the bicycle, one locks it physically to some other object, such as a bike rack, parking meter or other pole installed securely in the solid ground. Merely locking the bike frame to the wheel is not recommended because, although it cannot be rolled away, the entire bicycle can still be lifted and carried away. For a time, many U-locks used a cylindrical pin tumbler lock. However, most cylindrical locks can be picked by thieves using a common disposable Bic pen. U-locks with cylindrical pin tumblers should be avoided; though most manufacturers no longer offer them.
