The speed sensor will make it slightly more accurate, especially with starting and stopping. Without one it relies on the GPS signal from the head unit so there is a little delay when you first start moving and when coming to a stop before it registers you have stopped. I have been using it 1+ years without an additional "speed sensor" and haven't had any issues. Didn't want the extra parts, batteries, pairing, weight. Seems to be working fine without...
Nice looking unit. Had to 1 up me! 😀 I use the tether for mountain biking 🚵♂️. I thought the same thing, when I first saw the computer...that is is smaller than I thought. Sad to see that road bike now.
The thing I really like is the WiFi, which is what convinced me to get it. Yeah I still have a couple more videos to produce with the old bike. Wish I could go back pre-crash :(
