As I mentioned here I’m posting some old ideas which I don’t expect to follow up on myself.

Here is the transcribed text

Common keyed parts

Create a system of common-keyed parts for a bicycle + bike lock:
– A keyed quick release, works as easily as a regular quick-release for wheels, but has a key
– Keyed quick release for the seat post (believe this already exists)
– A rack that sits behind the seat (pannier rack?) with a variety of panniers, baskets + boxes which can be locked to the rack. They also can optionally be locked closed themselves
=> All of the above locking parts use a single key, which is also the key for a chain-style or U-lock style bicycle lock. So the same key used to lock up the bike would also be used to lock easily removable pasts to the bike.
