Bike Briefcase

Step 1 U Lock

Insert a u-lock through your bike rack so the open end of the lock is above the rack and the closed end goes below but hits a leg of the rack or some part of the rack that stops it from going all the way through.  This only works on some racks.  Attaching a plank of wood across the rack can also work if you don't have a u-lock.

I´ve make a mix between your idea and some others from here, to get a CYCLOCASE, using a Notebook case and elastic strips. I put some pictures in here  to help other commuters to do your own cyclo-briefcase!
