There are times when you want to stop for a little lunch on a ride without carrying your jacket and helmet in the cafe' with you. It is nice to have a locking option if you don’t have hard bags on your bike. The Kryptonite R4 Retracting Combination Lock is a convenient light-weight lock for light-duty security.
It is small enough to fit beneath most any seat or in a pocket of a tank bag. The R4 has a 2.6 mm vinyl-coated retracting 3 foot steel cable. It also has a 4 digit resettable combination, and the rollers are easy to grip and turn. So you don’t lock yourself out (or in), the lock has an anti-reset button that prevents accidental resetting. A really nice feature is the removable light for locking or unlocking at night.
Would I trust my expensive leather jacket overnight in the inner city to this lock? No way. However, that is not its intended purpose. It a convenient, light-duty lock that will foil light-duty criminals. The Kryptonite R4 Retracting Combination Lock retails for $22, but Competition Accessories has it for $18 on their website.
