I picked up an InterLock seat post lock from MEC in Toronto the other day. This was a funded Kickstarter project.
It comes in two sizes 25.4 & 27.2 My ST1 has a 31.6 seatpost so I had to drop in a 27.2 to 31.6 seatpost shim (available at a local bicycle shop). This is not my primary lock on my Stromer ST1, but a convenient and handy secondary lock with the added bonus of being a seatpost lock.
The silver ring is a 4.4mm seat post shim. Second photo from the InterLock website.
