Years ago all bike computers were wired and to a wheel sensor, magnet on a spoke. Most or maybe all of them would auto start.
I have a wired one on my rando bike, it auto starts, but that one was made by a company that went out of business years ago, no longer sold.
Does anybody still make wired bike computers?
