Especially in urban areas bike theft is a problem. That's why it is important to protect your bike with a secure bike lock against thieves.
Expensive mountainbikes and road bikes are very popular among pilferers.
When you compare the value of your bike with the price of a quality bike lock, you'll realise that it's actually not that much money, especially when you consider the loss should your bike be stolen.
The most important thing about locking a bike is to find a solid thing where the bike can be attached to, like a lantern or a balustrade.
Manufacturers of solid bike locks are companies like ABUS and TRELOCK.
