Used it on my way to work. Speedo was a little off on the Connie. 0-20 = 1mph, 20-35 = 2mph, 35-55= 3mph, 55-70 =4mph, 70-80=5mph difference (the bike reading the lower number). Since my bike has a dial speedi it was nice to look down and see the large digital display. Thanks for the idea Rosso , it will come in handy
