Ottolock Sidekick
Why does the Ottolock Sidekick make its way onto our list? The reason is simple. It is because this lock is very compact and affordable. But do not be fooled by its small frame. This lock actually provides some of the best security levels, due to a contemporary double-locking collar.
To be more specific, in most commercial locks, there is only one U coil, which will transform into a bent foot top. If someone wants to steal your bike, all they need is one single cut. Meanwhile, with this robust Ottolock Sidekick, robbers need at least three cuts to open your bike. And although the 12mm shackles are less strong than other models, cutting the lock twice can create noise. And surely no robbers would want that!
A major drawback is that this lock lacks an integrated frame mount. Also, it is too tiny to secure anything more than the frames. But if you are on a budget, this lock will sufficiently protect your bike.
