There is no such unit as "watts per mile".<br /><br />If you're talking about the power output of the motor at any one moment, the correct unit is Watt (W). If you're talking about the amount of energy consumed from your battery as you've covered some distance, the correct unit is Watt hours (Wh).<br /><br />For example, when the power output of the motor is at 100 W, if you continue steadily for one hour you would be consuming 100 Wh (Watt hours). If you're going at a constant 16 mph, you will cover 16 mi in that hour. The energy consumption per mile will be 100 Wh / 16 = 6.25 Wh (Watt hours), not 6.26 W (Watt).<br />joeweinhttps://www.blogger.com/profile/06668337577117358157noreply@blogger.comtag:blogger.com,1999:blog-18676999.post-46912073303180351282019-08-06T15:32:37.889-07:002019-08-06T15:32:37.889-07:00Watts is a measure of power. This is the rate that...Watts is a measure of power. This is the rate that energy is used. Energy is measured in Joules or Watt Hours. In your blog, you mention watts per mile - I believe you meant to say watt hours per mile. That tells us how much ENERGY is being used to go a mile. It depends upon the rate one uses energy (which is watts). <br /><br />So, if the battery energy capacity is 500 watt hours, and you are using 10 watt hours per mile, then the range is 50 miles. I should mention that you generally do NOT want to deplete all the energy in the battery before recharging. <br /><br />Hope this helps.<br /><br />TimAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-18676999.post-54500076615208358242019-08-06T15:28:19.785-07:002019-08-06T15:28:19.785-07:00Hey Kent,

I'm another "old codger", 86 as of current birthday, and was riding a Pocket Rocket Pro for about twelve years until I gave it to our grandson (med school grad as of this past May). I loved the BF PRP through the 16,000 or so miles that I put on it, but decided that it would be more useful to the grandson for his triathlons, etc,, so I acquired a "big wheel" Specialized Roubaix. The pleasure has been that we did a century for my 84th/his 26th birthdays.<br />Now I'm considering an ebike but my BF is in better hands, so I'll experiment with something else. <br />Nothing like getting to the age of wisdom when a little helping hand is both appreciated and enjoyed as it pushes you along to another century - in every sense of the word!agilenshttps://www.blogger.com/profile/07834425542250181837noreply@blogger.com
