Pretty darned easy actually. I leave my left hand on the bars and use the middle two fingers of my right hand against my neck. If you are under much exertion at all, the pulse is easy to find. Nearly every cycling computer has a clock that reads out seconds. Watch and count for 15 seconds - multiply by four and done.
