It's not a super expensive 25 speed Tour DE France racer or a fancy smancy ultra equipped mountain bike. It's a bike.
Mes Deux Cents, (see link on the right), a wonderful and picturesque blog I really like, had this funny bike lock overkill pic up. Perhaps the owner built this cycle themselves with love and it's priceless to them or they've been burned an awful lot by bike thieves.
I hope some thief doesn't see this as a challenge. Good grief!
