The Top 5 Bike Locks Reviewed
The beauty of cycling is that it can be many things to many people. For some, it’s a comprehensive and incredibly effective workout. It grants them fantastic cardiovascular fitness while also helping to tone and sculpt the core, legs and glutes. For others, cycling is a far more therapeutic, almost spiritual endeavor. It allows them to engage with their environment far more intimately than if they were to simply zip by in a car. Cycling allows us to enjoy our environs while also allowing the stress of the working day to drain away as we pedal. For some, cycling is simply a cost-effective and sustainable way of getting where they need to be, whether that be the workplace, a place of education or simply the grocery store.

With that in mind, it can be incredibly dispiriting and upsetting when we find an empty space or a forlorn single wheel where our bike used to be. Bicycle theft is an ever-present threat which cyclists need to be aware of. Aside from being careful and vigilant the most effective way to protect your bike is with a robust lock.

Strongest Bike Lock
All cyclists know and trust the Kryptonite brand. They’re well known for creating bicycle locks so strong and so impenetrable that not even Superman himself could crack them open. While their first offering in this list is a little pricier than its predecessors you know that the little extra cost pays for a pedigree and reputation that is known amongst generations of cyclists.
Sporting the same canary yellow as a New York cab, the Fahgettaboudit Mini offers the protection you need to, well, forget about anyone attempting to steal your bike.
The u-lock itself is made from some of the toughest steel on the market; 18mm max-performance hardened steel that gives this product a 10/10 security rating. New hardened double deadbolts offer increased strength and stability. The cross bar containing the locking cylinder is protected by a patented steel sleeve to protect the cylinder from dirt, dust and debris picked up in transit… Not that the locking cylinder needs all that much protection.
The disc-style locking cylinder is made to the highest security standards and is pick and even drill resistant. The lock comes with 3 stainless steel keys- incorporating a brand new design and including one LED replaceable key fob.
The lock comes with a lifetime guarantee and “key safe” program. This means that if you register your keys you can receive replacements within 2 days no matter where you are in the world if you should lose them.
In all honesty, the greatest protection the Kryptonite brand gives you is its name. When thieves see it, they show the same aversion that DC comics’ flagship character shows for glowing green rocks. All but the most foolhardy will simply back away, while even the most determined and resourceful thief will find it completely impenetrable.
The only restriction is its diminutive size. At 3.25” x 6” this is best suited to smaller bikes.
Perfect for – Anyone who wants a small, portable lock with the best protection you can get on the market. This is good for people with expensive bikes, such as an electric bicycle. Those looking for similar security qualities but in a larger size will benefit from…

The phenomenally strong chain is combined with an oval hardened steel crossbar for added security and hardened double deadbolt locking for incredible holding power. The cylinder is robust as you might expect from Kryptonite with reinforced an anti-drill/pull cylinder protection system designed with more than one million key variations.
Again, because the Kryptonite logo is so prominently displayed, this chain lock will give even the most determined thief serious pause.
