General advice

• If you aren't sitting on the saddle, then lock the bike with a good quality D-lock, the best you can afford. As a rule of thumb, it should cost at least 10% of the bike's value.
• Make sure the street furniture, that you're locking it to, is realy immovable. Don't lock your bike to a gate, if the whole gate can be lifted off it's hinges. Also tall poles are no good as fixing points, if the bike can be lifted over the top of it. Fill as much of the shackle as possible - this makes it more difficult for thieves to force it open.
• Remove the manufacturers' stickers from the frame+forks and paint them (badly) - it isn't pretty, but it should deter thieves.
• When your bike is at home, consider fitting a ground or wall anchor to lock your bike to (and always keep it locked up, even when it's in a locked garage).

Parts + Accessories

• If you have quick release levers on your wheels and saddle, then consider replacing these with allen key skewers (or better still, lockable security skewers). Another option is to use a cable to secure the wheels and use the D-lock as a padlock through the frame and cable.
• When the bike is parked, remove lights, pump, saddle and water bottles and take them with you.
• While cycling, a small carabina (from a climbing shop) will ensure that your panniers stay attached to your bike.

Alternative Bikes

• If you are buying a new bike and haven't got a secure place to lock it, then consider getting a folding bike (e.g. a Brompton) that you can take with you. Folding bikes also fly, car, rail or bus, but note -  the Manchester Metro requires you to bag a folding bike.

• Record the bike's frame number and description somewhere safe and consider tagging and/or registering it here it to help the police return it to you if it's found.
• The cheapest way to insure your bike may be through your home contents insurance. Alternatively, click here for specialist Cycle Insurance Companies.
