Cycling locks tested until breaking point

Sadly, you can’t always keep your bike with you. So on those occasions when you’re not there to keep an eye on it, make sure you leave it in good company – ideally secure in the custody of a seriously tough lock. It’s not an area to scrimp on, so we’ve rounded up a selection of the toughest and most innovative shackles around. Most of them have been independently rated by Sold Secure, an organisation originally set up by the Police and Home Office, but now administered by the Association of Master Locksmiths. They test locks for the insurance industry and provide a rating of either Gold, Silver or Bronze, depending on their ability to withstand attack.
