Hi, I've just bought a Trance e+2 and would like some sort of speed and distance readout. Normally I put a fairly minimalist speedo on my manual bikes (do we call them "manual" now?) but I am aware the E+ can do so much more via Bluetooth. I've seen you can get the two different displays from Giant but they are way more expensive than I am prepared to pay just to see my speed and distance. So what does everyone else use? I could put an old Android phone on my handle bars but I'm not sure I want that size display and the battery life will probably be bad (plus I'm a little reckless and usually crash a lot!). Is there another aftermarket solution? Otherwise it will just be a cheap and cheerful wired speedo on the front again.
