I got a new eBike and wanted to test the speed. In one hand the iPhone and off I went ;-) the White finger tells you the highest speed you did and that was 30km/h what I believe is the exact speed I had. These bikes are rated 32km/h but that might still be the case, I even think this app is 100% accurate ;-)) thanks, great app :-))
