The Masterlock Criterion bike lock sits at the top end of the bike lock market in terms of both cost and security. It sports a Sold Secure Gold sticker and costs close to £100, so sits resolutely at the business end of proceedings.
Unfortunately, this is not obvious when holding the lock and you’d be hard pressed to guess as much, because it looks and feels rather cheap. With a plasticky body, dainty 1.3kg weight and the shackle’s less-than-snug fit into the body, only the plush keyhole dust cover hints at the quality within.
The lock is a good 270mm-long with a frame mount included, so usability is convenient and the lock can be used on non-uniform bike racks or railings.
We’re not going to argue with a respected independent body like Sold Secure so you should be in very safe hands with this bike lock, and its low weight will be welcome when stowed in a back pack or on the bike's frame.
