  • Protects bicycle paint work
  • Small size could be viewed as good for moving around

This lock is small and well designed, but its strengths may also be its weaknesses.

With Knog’s reputation for kookie designs, it comes as no surprise that the Knog Bouncer bike lock is far and away the cutest lock we’ve tested (who’d have thought that a shackle lock could be cute?). However, we’d draw the line at dangling it out of a handbag and showing it off at parties (as Knog suggests on its website).

By far the best feature of this bicycle lock is that it comes with a silicone coating, meaning the Sold Secure Bronze-rated shackle is designed to protect your paint.

For some, the small size will be a welcome feature when chucking it in a bag and pedalling off to the next destination,  and for these glass-half-full people its small size (and its low, 860g weight) does make it very portable. Even so, for some other cyclists the fact that there’s not a whole lot of room inside that 120mm ‘D’ could make locking to a wide post or around an aero frame difficult.



A good looking lock, but the small size won't suit everyone
