Read a Calibike battery review at

“Battery: By the time I got back to starting point total distance was 24.7 miles. Display still showed all full bars except the half bar that is at the right side of the icon (961 display) When I got home, the battery took 1 1/2 hrs to fully recharge. I estimate the battery was about 25% depleted with 75% left to cutoff voltage.”
