I started with wired but never liked the wires, especially going to the rear and that was before I wanted (not needed) other sensors besides simply speed and distance. Went to wireless for a few months and then moved on to my smart phone with all the sensors, bells, and even whistles. It has GPS and Google maps tied into the app with simple swiping to change pages with the main page showing everything from tunes, to cadence, to you name it. Everything on that page but the map. Oh, and the speed is displayed in large top and center since that is still most important to me. With the sensor on the rear hub it all works on the trainer too.
