A theft data for the year 2014 from Transport for London made some interesting findings.

The top ten most stolen bikes in London were:

  • Specialized Camber
  • Specialized Stumpjumper
  • Carrera Villanueva
  • Norco Six
  • Burner B1300
  • Hong Fu Single Speed Foldable Bike
  • Felt Z95
  • Kona Dawg
  • Scott Specced XCR
  • Pake French 75

Out of these, the most stolen bike was the Specialized Camber, with 168 thefts reported in London alone. The next most stolen bike was the Specialized Stumpjumper with 137 thefts, and the Norco Six with 101.

Further recent data by Transport for London indicates that bike thefts have risen by 40% in the last 3 years.

Honourable mentions go to:

  • Gary Fisher Cobia (84 thefts)
  • Trek Fuel EX (80 thefts)
  • Pake French 75 (72 thefts)
  • Kona Dawg (71 thefts)
  • Scott Specced XCR (67 thefts)

The data above is based on thefts recorded around TFL bus and rail stations from November 2014 to October 2015. I suspect some of the bikes were stolen elsewhere and dumped around a TFL station.

Bike security is very important nowadays, with bike thieves is a major issue in some bike areas. However, Kryptonite’s New York standard U lock is an excellent way to protect your mountain or road bike. This lock comes with a 6 ft long cable to ensure you have enough reach to secure your bike to a couple of bike racks.

This lock comes with a 12 mm diameter in the shackle, providing excellent security against bolt cutters or hacksaws. The 6 ft long cable is thick to prevent the cable from being snapped or cut. To secure the cable, it comes with a locking mechanism, to ensure the mechanism is secure, the lock comes with a sliding dust cover over the locking mechanism. This is a great idea and something I haven’t seen before.

6. Bell Catalyst U-Locks

Our rating: 8 / 10

Bell Catalyst U-Locks

These U locks are the perfect theft protection for your bike. They are smaller than the Brooklyn U locks so you have more room to maneuver the lock around your bike. The Bell U lock is designed to be lightweight, but it’s definitely not going to slip out of your hand.

These U locks are easy to use and extremely sturdy. You can place the lock on the ground in order to stand your bike up, which is especially useful if you have your bikes up against a wall so you can�t access them from the ground. These locks also come with a ribbon cable as well as a plastic cover for the keyhole to make sure your lock stays waterproof.

The best thing about the locks is that you can buy them in either the 6 inch or the 12 inch size. The 12 inch lock is obviously a lot more secure, but it’s also a lot bulkier to carry in a backpack, so it just depends on how much room you have. I just make sure I use the smaller lock when I park my bike in a crowded area.

7. Kryptonite Kryptolok 12.7mm U-Lock

If you’re not a big fan of carrying a pocket-sized lock with you everywhere you go, then this could be the best anti-theft lock for you.

The extra thick (12.7mm) chain on this lock is hard to cut through with a standard bolt cutter.

Another awesome feature is the anti-wobble feature, which helps you from accidentally pinching your bike tire during locking or unlocking your bike or rack, and allows you to take the lock out of the bracket during locking.
