Last night I fulfilled a long-held desire: I installed a hidden switch that, when pushed, would restrict my bike to the UK legal limit of 15mph.
I used a locking push switch from Maplin:

I wired it up to my Lyen 12 Fet controller's board, one wire to X1 and the other to ground (I had already configured speed 1 appropriately using the programming cable). Then I mounted it under my saddle (as you can see in the pictures), in such a way that when my gel seat cover was put back on, you can't see it, but you can still operate the switch. The wiring all follows the battery connection, so you'd really have to know what you are looking for in order to know that it's there at all. I may even tape that section of battery/switch cabling up with black electrical tape.
Works like a charm, and I'm really pleased with this simple hack.
(I know that not all of the screws are in the controller in the photos - they are all there now that the job is finished)
