It would be great if you can locate your wheel incase of theft.
@indovisual Pretty much everyone's biggest wishlist item. Doesn't even seem to be a good alternative solution out there for this yet, aside from just strapping your iPhone to the bottom and hoping the thief doesn't notice.
Use a tile, mount it to the bottom.
I thought about mounting this tiny thing (of course in a housing) to the OW: https://www.kickstarter.com/projects/1566751732/tracker-extremly-power-saving-gps-gsm-board
It could be powered through the OW's battery for quite a very long time - it just has to send updates when the bad guy turns it on the first time. If had a bit more time, I'd definitely be interested in developing a nice gadget out of it.
