Over 100,000 bicycles are reported stolen in the UK every year. They are a popular target with thieves because they can easily be sold. They should be locked whenever you leave them, even if you are just popping into a shop or the library.
The best type of cycle lock is made of a loop of solid metal (D lock). Thin chains and wire loops deter casual thieves, but can be easily cut with the right equipment. Don’t be tempted to buy a cheap D lock, the best are the type designed for motorbikes – expensive, but your bike is likely to still be there when you return. Try to use two locks or a long hi-tensile strength chain that you can wrap around both wheels, the frame and the post.
Always lock your bike to something solid like a lamp-post or railings, but never to itself. It can be quickly lifted and placed in the back of a van with the locks removed later. If you have quick release wheels, take off the front wheel and lock it to the frame and back wheel.
