So, today i went a-welding again. Maybe for the last time on the project! I welded tabs onto the frame to mount the sheet of aluminum that holds the electronics, as well as made one major modification of the battery frame because there was one section that was too short.
The only pic i have so far is this one that I was using to show the “thinking stool” over at elmoto.net (http://www.elmoto.net/showthread.php?678-show-us-your-THINKIN-stools!-(again…))… Read the rest of this entry »
i’ve been trying to bench test the motor to ensure that:
Upon the first try, it failed. I had most everything setup properly,… Read the rest of this entry »
So, i’m back from the TTXGP practice runs today at Infineon Raceway in Sonoma, CA. Ok, so it’s actually the “AMA Moto Jam”, but i’m mainly interested in the TTXGP race and teams.
Going into the event, i had no idea what it was going to Read the rest of this entry »
As i as describing in my previous post, i’ve been struggling with how to make sure that the batteries stay in the frames. I went over a bunch of different ideas, and thought the latest plan was to weld or epoxy bars to the Thundersky end plates sort of like this:
End plates showing welded or expoxied bars
Then, tapping holes in the bars/end plate and using screws to keep them anchored to the angle aluminum. This allowed me to keep all of the … Read the rest of this entry »
Ack, no updates in a long time. There’s actually been a bunch of stuff going on too!
In the middle of January, i received my batteries from Thundersky and EVComponents. Woo! Here are a couple of iPhone pics of the batteries.

Unfortunately, when i ordered the batteries, Read the rest of this entry »

So, i mentioned in an earlier post that i originally thought i’d be able to build a bike for a couple grand. Well, after thinking about my desires for an electric motorcycle, that cost jumped a bit….ok more than a bit.
What i’m hoping to get in the end is a motorcycle that will:
That being said, i decided to throw as much in the way of batteries as i thought i’d be able to get away with. A guy in Florida with the screen name “remotecontact” on elmoto.net started on a project similar to me a few weeks before i got started. He started with a 2009 Ninja 250 and is planning on using the same EnerTrac hub motor, with 32 Thundersky 60Ah batteries. that works out to 6.1KWh.
I first found Elmoto.net (http://www.elmoto.net) when I was doing research on the Electric Motorsport GPR-S. At that point, i was kicking around the idea of upgrading from my Zapino to a real moto and was considering buying one.
I can’t remember at which point when I went from thinking about buying an electric motorcycle to building one, but I’m pretty sure that elmoto.net was a big of the reason (and i thought i’d be able to build a bike for cheaper than i could buy one…this is yet to be seen though).
The group of people that frequent the site have been exceptionally supportive to me and everyone else who chimes in asking questions and talking about their projects.
There are a couple of other sites that I peruse regarding electric vehicles and motorcycles such as endless-sphere.com (http://www.endless-sphere.com/forums) (which is more geared towards bicycles, but has an incredible amount of information about low level battery tech, charging, and management. And also is where I found the EnerTrac hub motor), but I find that elmoto is the place I go to first when I need help, support, guidance, or just random information about EVs in general, but especially about motos.
