Range test performed today with the same bike, a total of 12 miles on a closed loop, essentially my one way to work. Battery still showed charge available at the end of the test which consisted of no pedaling whatsoever. Probably would not have made the advertised 20 mile range but 15 seemed likely. GPS stats sowed 15 mph avg speed for the duration of the ride. Recharge took 4 hours. Charger got quite hot and did not indicate the charge was complete but the batter indicated otherwise.
