I have the Bolt and I use it without the speed sensor on my commuter bike and with the speed sensor on my road bike. The tracking comes out the same when I do the same rides. While it isn't a big deal to swap the speed sensor from one wheel to the other when I'm in a rush out the door going to work I don't bother. The only real difference is that without the sensor the speed reading is a little lagged.
I've never used the live track feature. Why do I want anybody to know where I am?
