Hi all
After seeing the term efficiency banded around everywhere I thought I would have a go at putting a figure to the name.
My best Idea is not given as a percentage maybe I can work out a formula eventualy for now just a number can be got from this concept.
If anyone has a better idea say.
Ok efficiency is the ratio of watts used to speed attcheved,this would be:-
watts /speed for comparison the speed should be in the same units mph or kmh.
The lower the number the more efficient the motor,for comparison the best readings should be on the level with little wind.
I'll start the debate with readings I have on my ebike resently.
speed 25mph, watts 850
using the formula I have proposed my eficiency number is 34
these readings were taken on the flat in little wind.
Try out the formula yourself and post a reply.
You could say I'm laying down a gauntlet.
Thats all for now
