Locks that work

Also you Dutchies, have those fantastic, handcuff type rear locks. Mostly look like they are attached /part of the rear brake bolt.

My ex, had her house keys etc. on the same ring, so when she was not on the bike, the rear was always locked to the bike.

Great invention for small short trips- quick nip to the shops etc.

I have wondered why a small version has not caught on here.

You can buy them in most LBS. But they are kind of heavy and overpriced for what they are.
