The Electric Motorcycle
Everything you wanted to know about building an EV Motorcycle

Step 6: Testing


Your first test of the electronics should be done WITHOUT the chain on it. That way if something is wired incorrectly, your bike will not end up in the neighbor’s yard or even worse, your living room.   The Alltrax controller has a LED on it to give you a status check of itself.


Motor break in: IMPORTANT INFO.

A new E-Tek motor will need to be broke in. The brushes need to seated. I am sure you will want to play with all this new HP, but the first few hours of running the bike need to be in 25 to 30 MPH range and accelerate slowly. After that, have fun!!!! 

Here I am for the first test ride. Several people looked at the really quiet bike with a few asking questions. It all worked correctly so now we need to make it look good. 

 

Coasting: Learn to ride differently!

Most cars and bikes will slow down when you let off the throttle because of the internal resistance of the motor and transmission. Not so with a direct drive electric motor.  When I first starting riding this bike, my habit was to give it throttle until I needed to slow down and then hit the brakes. With this bike, you will let off the throttle and the bike will coast at almost the same speed. Now I needed to learn to let off the throttle long before I needed to stop. This will increase your MPC (miles per charge) distance by at least 30% or more. You will not be holding up traffic at all. It is just a different way of riding this type of bike.

Reg-Gen Braking

I was asked about Reg-Braking on this project. This is when the motor generated a charge to the batteries while at the same time slows the bike like a brake. Unfortunately Reg-Gen Braking is not practical for a bike as it does not have the mass like a car (or golf cart as they use it now) does. The added weight may kill the range. It is also a added cost of about $500.

Step 7


The required disclaimer: This information is about what we learned on our project and is not intended to do anything but show you how we did ours. LEARN all you can before starting any project with this much voltage.  A 9 volt battery, applied correctly, can kill you. Think about what 6 - 12 volt car batteries can do if not wired correctly.
