Electric Race Bike

[Jay64]

A *mostly* stripped frame.

[Jay64]

The motor, the arrows are the upper motor mounts.

[Jay64]

The measurement from the center of the steering stem tube to the back of the motor cavity of the frame.

[Jay64]

If both of the AngiMotors are going to be sticking out on either side, that is going to have to be one long shaft connecting them.

[jonescg]

You can move the motors further forwards, and tuck them inside the frame a little. My motors are only about 190 mm apart if I recall... The diameter of the Agni is only 250 mm, so you won't have any problems with the drive sprocket being too far forwards.

Don't the motors have to be out in the wind? Also, didn't you use a different frame then the one I'm using? Not sure if the spacing will be the same.

[jonescg]

The motors will pull air from the endplates and spit it out radially. So it's not going to help them much by being right out in the breeze, except mean you need even bigger crashbars around them, potentially affecting your ground clearance at lean. It also means your toes won't be touching the motor

The spacing will be different for sure, but it's not going to matter much. I would recommend the motor shaft be kept as short as practical though.

[Jay64]

So just the end plate needs to be out in the wind? I was playing around with some crude mock ups on Sketchup I did, and it seems like if I am going to have the shaft line up with the chain, the motor needs to be sticking out rather far on the one side.

I just turned down the deal to race a Lightning motorcycle today. So now I really need to get this bike built in time for the first race.

This is a great thread. Cant wait to see what you end up with.

Makes my moped build look very silly indeed!

[Jay64]

The Soliton controller just showed up today. Damn, this thing is HUGE. Glad I went for the JR and not the full sized.

I don't know, I think all EV builds are great. I would like to get the chance to see your moped one day.

[sflorlando]

You just might...I was in your area this past weekend doing the solar thing. And by solar I mean soaking up some rays laying on the beach!

That controller is huge. Specs are quite impressive though. Someday I will do a full motorcycle conversion.

Ken, I go up to Orlando quite a bit. Maybe we'll meet up one of these times.

[sflorlando]

definitely! The only ebike I have ever seen was my own, would be cool to pass ideas by you and nerd it out a bit.

[Jay64]

Ok, This is a very crude attempt at mocking up in sketchup. I believe this model is actually a GSXR 1000 frame, it definitely isn't exactly a 600 frame. But it was the closest thing I could find to get the general layout. My crude model of Dual AgniMotor 95R motors, and zippy flight max cells. I actually got lazy and both packs are the same size, even though one should be 4s instead of double 5s. But I figured it would be better to make sure there was room for a larger than needed pack than to go for a smaller than needed pack.

[Jay64]

Ken, if you want to check out some awesome electric bikes (bicycles) you need to check out Drew's builds. He is in Orlando too. Stupid fast bikes. I love um.

[sflorlando]

Thanks, Yes I have sent him a few PMs's. Id love to see some of his bikes. Crazy fast stuff.

[drewjet]

Maybe when you are ready to work on that pack we could all get together for a nerd session

Good thing you chose a Gixxer for a donor bike - they really are the wheelbarrows of the sports bike world And your batteries will fit down nice and low. You should be able to sit this thing under the tank cover pretty comfortably.

[Jay64]

Sounds like a plan to me.




Chris,
Yeah, working the basic dimensions out it looks like there is going to be plenty of room. Now I just need to work out the details for the motor mount/battery tray hardware. I've got it in my head, but there seems to be an electrical short somewhere between my brain and my drawing hand.

[sflorlando]

Im totally down for that!

Right now I am stuck on smelly petrol, my bike is currently dead with a smoked hs3540 and scooter is still in the works.

The race bike will be so slick when done. Cant wait to see it.

Ken

Awesome. We need to get on this if it's going to get done on time. I am only working part time right now, and pretty flexible, so just pick a day and time.

Ken

See it??? I want to drive it!!!!

[sflorlando]

Yes I concur. Im a network administrator for a local accounting/tax group in orlando. Once the busy tax season is done, I will have more time on my hands, finally ending these six day work weeks!

[Jay64]

I'm getting a little bit more of a hang of this software. Now I figured I would try and figure out how I was going to do the series/parallel connections of the packs.

[Jay64]

I have the packs paralleled on bus bars into strings of 8 for 40ah. It is kind of hard to tell in these pics, but each bus bar is sticking out 1/2" on opposite sides from it's sister bus bar on the same string to give something to connect the strings to. Each string has a 1/2" gap between the next string to leave room for each string to be encased in 1/4" polycarbonate boxes, and connected in series to the next string.
