Bike thefts up so City of London police produce comprehensive anti-theft guide

The City of London police reports that bike thefts increased 25 percent year on year for the period April 1 to June 30.

To help combat the tide of light-fingered scumbags swiping bikes, the police have produced two videos and a comprehensive web page showing you how easy it is for some locks to be cut and detailing the best way to stop it from happening to you.

As you can see in this video, an inexpensive cable lock can be cut in seconds.

The City of London police’s cycling expert, PCSO Scott Green, talks about some of the security options here:

The most useful part of the campaign is a comprehensive guide to choosing and using a lock. Key points from the guide include:

  • Get your bike on the Bike Register so that it is more likely to be recovered if it is stolen.
  • Store your bike inside overnight if possible.
  • On the street, lock your bike to a proper bike stand, and in a place where it can be seen.
  • Lock your frame and both wheels to an immovable object.
  • Use a good quality lock. Spend 20 percent of the value of your bike on a lock and use two different locks when leaving the bike for any length of time.
  • If using a chain lock, make sure it’s not resting on the ground where it can be more easily smashed open.
  • Fill a D lock with frame and wheels and use one that’s as small as practicable to stop thieves using bars or jacks to lever it open.
  • Point your D-locks lock mechanism down so thieves can’t pour things into it such as glue which forces you to leave the bike for them to attack the lock later.
  • Don’t use a thin cable lock as your only security.
  • Look for Sold Secure ratings.
  • Keep your spare key safe and make a note of your key number.
  • Get insurance.

Our official grumpy Northerner, John has been riding bikes for over 30 years since discovering as an uncoordinated teen that a sport could be fun if it didn't require you to catch a ball or get in the way of a hulking prop forward.

Road touring was followed by mountain biking and a career racing in the mud that was as brief as it was unsuccessful.

Somewhere along the line came the discovery that he could string a few words together, followed by the even more remarkable discovery that people were mug enough to pay for this rather than expecting him to do an honest day's work. He's pretty certain he's worked for even more bike publications than Mat Brett.

The inevitable 30-something MAMIL transition saw him shift to skinny tyres and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.

I am pretty lucky as I work in a very secure area which has cameras watching the bikes, at home I built a key secured 7ft by 5ft bike shed, and bought off a local fabrication place a galvanized bike stand and coach bolted it to the flags, I then have two bike locks wrapping up my three bikes one of them locks is sold secure the other is just a chain wrap around...I put pipe lagging around the bike stand and the metal parts of the lock also..... I'm pretty confident mine are safe.

Mine are on immobilise.

Are bike register and immobilise two separate systems, do bikes need to be registered on both??

Locked even worse than the one in the photo.

I'm waiting for some new super light and strong material to come along, what's the point of having a 7kg bike if you've got to carry 2.5kg of locks and chains/cable.

And if your bike cost £3k then £300 of locks would be overkill. My gold rated lock was £25ish.

/dont have a £3k, 7kg bike btw.

Is there meant to be a video on this page?

Yes, they're different.
I asked a Met policeman doing bike marking that same question, and he said that the Met use bike register, not immobilise.
Apparently it's because bike register uses a tamper proof (supposedly) marker, whereas immobilise just uses the frame number, which for some reason isn't a good enough identifier for them.
