Kent Bikes Now Alan and I do ride just about daily we're nerds so we have used recording Watt meters to inform us how many WattHours per mile we're utilizing. On a recent reasonably hilly journey, with my e-assist set to levels 2 or three , I used 214.7 WattHours to go 37.7 miles. My arage velocity was not tremendous fast however not turtle slow both, I averaged thirteen.6 mph. My bike has a modest 250 Watt motor and a 12.5 AmpHour 36 Volt battery.
