The Kryptonite KryptoLok Series 2 Mountain Bike U Lock is a extremely good deterrent category product boasting hardened performance steel.   The Kryptonite KryptoLok Series 2 Standard U Lock will protect your bike from opportunistic thieves with hand tools.

This is the standard product in this series, but also available in a wider Mountain Bike version and a longer version.

But to stop a determined thief you had better consider a high manganese product such as the Kryptonite Evolution Series 4 integrated chain or the Kryptonite New York Fahgettaboudit mini.



European Testing Agencies

In Europe, independent testing agencies put locks through their paces to see how secure they really are, or in some cases are not. Kryptonite holds more than 45 approvals at Sold Secure (UK), ART (NL), N.F. (FRA), SSF (Sweden) and VAREFAKTA (Den). These agencies attacked products with every bit of malice the testers could throw at them and they still held up. We hope this brings peace of mind to our customers; it does to us and we use the products every day ourselves!
