Electric 450 CRF conversion.

[Arlo1]

I have not spent as much time on ES as I used to. I have been busy with many things. One of them has been this bike.
About 2 years ago I picked up a 2005 CRF 450 with a rod sticking out of the cases. From there I started figuring out how I was going to make a fast and fun to ride Electric MX. I 3d printed about 5 jackshaft housings until I got a design I liked and 3d printed a jackshaft just to see how my design works out. I then found a Zero SR IPM R motor and took a sevcon Gen 4 size 6 off of another bike. I was able to find a 2018 Zero Longbrick from Hollywood electrics. I had to cut and widen and weld the frame to fit the battery in. My goal was to keep the motor and battery as low in the chassis as I could. Anyways. I will post all the build videos and try to add some info to this later.

Hey Thud,

Nice to see your post! Hope you're well.

What interesting project are you building?

I sure got a kick out of that twin motor two speed bike you took to New Mexico all those years ago. Talk about bad ass!

Good times.

Nice, very similar to my plans for the yamaha build

Setting up the sevcon looks easy for you, it seems like it is not for most people
I am struggeling with the controller choice myself, it is hard to find a good powerful controller if not going the sevcon direction.

Thanks man.
About 25 lbs more then a factory 450. I need to weigh it once the 3d printed parts are on it.
