Thanks, great pics and they are nice looking bikes. What kind of mileage are you getting from a full battery? Yesterday, I depleted the main battery and a Range Extender in 48 miles riding mostly flat bike trails averaging slightly over 18mph. I rode in Sport Mode until I hit 12% battery and then it dropped the power level. I will try the same ride this week using ECO mode. At my age (69), 6'5" and 205lbs I don't expect the mileage younger, lighter, stronger riders get but I was expecting better mileage than that with 150% battery in Sport Mode.
