Tour De France cycle safety Always lock your bicycle wherever you leave it and make sure it's left in a well-lit public area with lots of people passing. Stations and public buildings often have designated areas with bicycle racks. Try to lock your bike to an immovable object that the bicycle cannot be lifted over, and that cannot be broken, cut or removed. For maximum protection use two different types of lock (a D-lock and robust chain and padlock is ideal). Always lock your bike at home, even when it is in your garage, flat or halls of residence. Investing in a ground anchor to attach your bike securely to a wall or concrete floor offers added peace of mind. Enjoy the rest of Tour De France and keep your bicycle safe and secure.
