Wh/km

Post by Gow864 »

I'm in the process of converting an old 125cc Suzi.

I'm using a mars electric and a 48V/40AH TS battery pack, Kelly brushless 300A controller (I'm going it limit to 3C). Can I work out what it's Wh/km will be? approximately?

Cheers,
Gow.

This seems to be a reoccurring problem.
Finding bike aerodynamics is worse and highly variable due to the rider.
Don't forget the Wh/km will vary depending on speed.

Here is a typical sample but as I say yours will be different.
Antiscab do you have any actual running data that could be used as a guide?

So the short answer is NO but the long answer is YES.

Hi Gow,

i can give you a data point.

from the mains my average (for the past week) is 64.1wh/km.
