Extra security

D locks and cable locks only allow you to lock the frame and one wheel of your bike, so you may decide to buy two D locks to secure both wheels, or to buy a cable lock to secure the second wheel. Alternatively, you could combine your D lock with an ‘extension’ cable – a flexible cable with open loop ends which you can loop through the wheel you haven’t locked and secure to the D lock before you lock it.

If you have quick release mechanisms on your bike, it can be very easy for thieves to steal your saddle and wheels. You may wish to replace the quick release mechanisms with ordinary bolts or nuts which fit a spanner or allen key; or you can buy special locking nuts which can only be undone with a specially designed version of an allen key which is sold with the bolt.

If you’re unsure about this, your bike shop should be able to advise you and fit the replacement if necessary.
