More than a bike lock!
Trelok is piece of mind... this Germany company has been since 1854, I'm no math expert but that's over 160 years. Any company that has been making locks that long must make solid products.
Easy to transport folding locks offer great security and are easy to attached to any bike that has H20 bosses. For the daily commuter that may not need a high security solution the seat tube mount locks are a way to secure your bike and because they are attached to your seat tube, you will never forget your lock again.
