Aerodynamics come into play at higher speeds but at low speeds it's not as important. I had fun playing with this tool http://www.wallaceracing.com/Calculate%20HP%20For%20Speed.php I plugged in some street speeds and frontal area makes a really big difference over 40MPH. sean On Thu, Nov 12,

You would need to include the driver. On a car the difference between 2500 and 2700 is not as significant as 500 and 700. However I have not converted a motorcycle so I am not even sure the rule of thumb applies Sent from my Verizon Wireless 4G LTE smartphone Original message

50Wh per mile is way too optimistic. A Zero SR, which is a state of the art bike, lists a nominal battery capacity of 11.4kWh. Range on the highway at 55mph is listed as 98 miles. This gives 116Wh per mile. Al On 11/12/2015 1:59 PM, Ing. Marco Antonio Gaxiola via EV wrote: Considering
