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.
