Masterlock's funky Streetcuff design has been around for a couple of years and the design has been tweaked and improved strength-wise in that time.
The police cuff style remains the same, but it's good to see that it now comes complete with a neat bottlecage boss mounting bracket. The downside is its size - the 65mm cuff hole limits its applications to road-based bikes - we tried it on a couple of fat-tyred mountain bikes and it simply wouldn't fit. The design also means that you can lock it to the bike and to whatever it's anchored to, but you will need a secondary lock to go through at least one of the wheels.
The cuffs got through the first test - previously we'd broken these at the rivet (which is much improved), and after five minutes we'd simply managed to remove most of the plastic covering. On to test two and just inside 35 seconds was all it took to sever the cuff section and remove our test frame. It's a quirky design that's great for quick stops when the bike is in sight, but for longer duties a second lock would be needed.
