One thousand kilometers on an electric bicycle
By Craig Morris on August 16, 2016

I have spent two months riding my new e-bike. Here’s what you are missing out on if you don’t have one.

I know this is not directly ebike related, but it is an interesting build and looking outside our ebike work may help stimulate creativity.

They used an Arduino mini computer to run things and used an ebike controller to run a Subaru alternator as a motor!

Coffee Shop / Watts, Volts, Amps, Amp hours, Watt hours...a discussion
« Last post by Tom Cole on August 17, 2016, 05:43:28 pm »
Here is some basic math and information that is good to know when researching ebike batteries, controllers, and motors.

Amps = I
Volts = V
Watts = W
Amp Hours = Ah
Watt hours = Wh     THIS IS THE FIGURE YOU WANT TO KNOW ABOUT BATTERIES!

Amps x Volts = Watts
Watts/Volts = Amps
Watts/Amps = Volts
Amp hours x Volts = Watt hours

If we analogize these terms to a river, volts would be how many feet the water is going to drop from one point to another, or how fast the water will run, it is really about potential...kinda like water pressure.  Amps would be how big the gates in the dam are and the water behind the dam to be dumped into the river is amp hours (capacity).  Watts is a measurement of the power generated and watt hours tells us how long peak power is going to last.  A controller is what regulates the opening and closing of the gate based upon power requirements.
