This new Kryptonite Kryptolok std bike lock includes a flex cable and introduces many improvements which make it safer than other brands’s locks.It is recommended for medium-high theft incident areas, having a security mark of 6/10. Each manufacturer rates their own locks – that is why this one is safer than other brands' locks with a higher number.

It has been awarded the Sold Secure seal (Silver level) by an independent organization. Its flex cable will let you secure the front wheel of your bike, to add an extra security feature. We highly recommend to use the U-lock, not this one independently. This cable is only a complement to the lock itself, and does not provide the same security level as the U-lock on its own.

MORE INFORMATION: How to choose the best lock to protect your bike?



Kryptonite has created an offer of anti-theft protection associated with all its locks (ATPO). This is a programme created in 1978 that reimburses a specific amount to customers registered to the programme if their bike has been stolen by opening or breaking the lock. ATPO is not a bicycle insurance and is not subject to any insurance company. The offer is made by Kryptonite.

About Kryptonite

Kryptonite is possibly the most relevant padlock brand in the world thanks to its wide selection of anti-theft devices and because of the extreme quality they give to all their products allowing protection for all bicycles. There are different types according to each need: U-locks, cables, chains, combination locks, etc. All this has given the brand numerous awards and has allowed it to distribute its locks, both for bikes and motorcycles, from its headquarters in Canton (Massachusetts, USA) to the whole world.

We at Santafixie recommend the use of professional padlocks. It is better to invest in a good lock than to regret the theft of your bike. At least one U-shaped lock, and even better: two (one for the frame and rear wheel and another for the frame and front wheel). This way it is practically impossible for your bike to be stolen.
