Electric EX 500

My son and I recently converted an EX500 with a 3 phase PM ZERO style motor powered with 12 Nissan leaf batteries and on board Type II charger.Still sorting it out but seems very fast and lighter than stock. Would like to improve front brakes. Looks like I can't post pics.

Welcome! Participation is key...I believe 5 posts will enable linking and pic privileges, 15 for PM.

Welcome! I assume you were trying to add pics from a hosting site. I've recently noticed that members with less than 5 posts have been able to post pics that are uploaded to the site from their computers. This is a good opportunity to test that. Would you mind trying to attach them from your computer?

Instant acceleration?
How much $ invested into it?
Looks like a fun project.

Funniest thing I've heard all week

Thanks for doing that. It cleared up a mystery for us. We had a software upgrade a while back and we're still learning a few things about the results of it.

I am pretty sure the quote is accurate (1943) and explains why it took me so much tome to upload a pic.
Probably could have uploaded something larger than a thumbnail if I were more IT savvy.

The acceleration is impressive with the motor controller set to pull 350 Amps and with the current set up the top speed is 92 MPH. We have not made the long ride yet to find out the range.
As far as cost, I will say that the ZERO motorcycles seem not that expensive after buying the electrical components to put the EV-500
on the road. But I could not have found a more rewarding Father and son project, Priceless!

Some members may remember it took me over a year to figure out how to post picks .
In my defense I literally had one months experience with a computer when I first joined the site.



Now I'm a picture posting fool .

Awesome project for you & son!

Would you say acceleration is faster than stock?
What is total weight of bike compared to stock?

I'm particularly interested in EV for racing as range isn't important. But a better power-to-weight ratio than current bikes and faster acceleration would be really worthwhile.

Hello Danno, yes the acceleration is faster than stock and can be changed with changes to the software in the motor controller. I am not sure how to measure the acceleration, but it is quicker than my 700 Interceptor.
EV500 weighed 40 lbs less than stock. If we can get better measurements we will post them.
Thanks for your interest.

Another interesting aspect that I'd like to investigate is 2-wheel drive! After getting to certain power-levels, further increases in speed is difficult due to rear-tyre traction. Hence all the developments in DBW, traction-control, wheelie-control, etc. Would be interesting to see how splitting up that power and putting some of it to front tyre can improve speed and control as traction would be more balanced.

2 wheel drive for MC is a waste. the weight transfer unloads the front tire and all you will get is wheelspin . we won't even mention the horrible effect to the handling. I took Audi and several others 25 years to get 4wd to work on a road car.
Don't

Audi dominated IMSA GTO racing in '80s and were saddled with increasing ballast weight again and again. If someone told them not to bother in beginning, and they actually didn't pursue that path, it never would've happened. Today with modern electronics, lots of issues can be resolved quickly via software.

I'm thinking about section in turns after apex as you're standing up coming out and before straight. Rear-traction on back-end is always more limited than front due to combined cornering and accelerating demands. Yet front tyre still has plenty of grip and a lot of time that's wasted as it's aimed towards outside of curve just to balance sliding rear-end. I want to leave TWO blackeys coming out of turns rather than just one!!!

you will fall down.
Check the 2" gap under my front wheel at a start. tell me how a driven front wheel will help my acceleration.
In cornering the front tire has all it can handle with just turning the bike any additional input force acceleration or breaking will make you fall down or go much slower.

Again, I'm not talking about in straight line.

Sure, from braking to apex, front-tyre is typically more overloaded than rear.

But during transition from apex to straight-away, front-tyre has surplus grip there due to rear-tyre being overwhelmed. With software, we can balance drive-traction between front & rear in this area. Then remove more and more power from front-wheel coming on straight as front-end gets light.

Hey, if anyone's gonna probe new 2wd tech, I'd put my money on either Honda or Yamaha R&D departments.

i seem to remember reading Yamaha exploring 2WD some years ago? If so, the idea seems to have been discarded, at least never reached fruition in any of their production.

I doubt, even *if* successful, new motorcycle sales market would support the immense, added expense of technology involved. Whatever tech invested has got to return in market share and $$$ for any major manufacturer. I don't believe demand is there.

Just realized major threadjack occurring here.....out of respect to OP thread....I'd suggest to open new thread on this subject.....anybody?

Yeah, it'll be only for racing initially due to unfair advantage.

Hub-driven wheels have become standard with hybrid tech. Impossible just couple years ago, but modern software is what makes it possible. Heck, latest Lotus Evija has 4wd with close to 2000bhp!!! Impossible to control without software. Imagine heel-n-toeing 4 separate accelerator-pedals! AAhahahhahahahh!!!!

Back to EV500.

Could you please provide some links to equipment used for retrofit?

Thx

This is rad! My EX is still going with the original engine, which I will take care of as best I can, but when it finally gives up the ghost, I plan on dropping it out and converting the bike to electric. I'm bookmarking this thread for the future.

Not to dissuade you from building such e devices, but :
Some thoughts on electric driver anything. In short efficiency . that is the power created in you e device seems prodigious but when you look at the power consumed to generate the electricity weather by wind coal or even water, plus the losses in transmission, the net power of your device comes out a negative number.
Batteries are a joke for transportation devices. the only thing that currently works is a hydrogen fuel cell. I'm not sure of the power required to create liquid Hydrogen. Maybe when nuclear fusion become a reality, or wireless transmission of E power is a fact (ala Tesler) .
As long as paying for power is fact, nobody is going to make much headway on creating a free power system.
I see all e transportation devices short of Public trans as a very expensive toy

What's really strange is when someone switches to EV, I would suppose their previous cost in petrol would be transferred to their electric bill. And end up costing more. So far, of five people I know who've traded in their petrol auto for EV, all have said their electric bill has gone up less...

I supposed with free charging at office and universities, the petrol cost was transferred elsewhere. Are there any studies out there on this switch for consumers?

They're keeping it a secret. Once everyone is converted to electric, and we do away with gasoline, expect the cost of electricity to rise at a geometric rate.
It's a scam I tell you.
