Motorcycle conversion from GT250 Comet to 8kw hub motor, 8.8kwh automotive EV battery reuse

[Elec’73]

Hello, just finished this motorcycle EV conversion [ 2004 Hyosung GT 250cc Comet chassis ] reusing automotive EV battery modules instead of building battery packs ”from the ground up”. Are there any other experiences with automotive EV module reuse on motorcycles & feedback ?

Hey, do you have any more pics or info on the build? What exact cells are you using? What controller? What motor?

(mostly asking because these photos appear four weeks ago on someones instagram who is in the in the philippines, and not kentucky as the op stated...Was a bit weirded out originally since there were so few details included, and one thing about nerds like us is that we love to share all the tiny little details so I did a bit of digging and found that post...)

Yeah, I'd love to hear more to, if this is indeed OP's legit build. Looks really clean with the automotive modules

Yes, absolutely; I will gather and share the pictures showing the storyline of this build with more detail. Looked like someone pinged a couple of pictures I had put out there. Nice!

Titled in KY as pictured below with a couple of fresh views that your instagram dude has not pinged yet, since these were taken today. For the specs : 72V 8000W hub motor - Fardriver ND84680 Controller - JKBMS 200A 24S - I recently installed 4x battery modules from a Hyundai IONIQ5 / Kia EV6 at 88.8V Nom x 100Ah+, so right at 9 Kwh - previously had 3x battery modules from a Renault Zoe EV at 88.8V x 72 Ah that you can see in one of the initial pictures. 12 Lbs weight saving with the newer battery pack. I will upload pictures of interim steps in a separate post.

The instagram link in your comment is inop now, after your instagram dude was politely asked to take my pictures down.

Yeah, indeed, legit it is and a low cost build (material and Capex/tooling). There is no welding (metal frame), no 3D printing. Simple cutting/grinding, drilling and assembly with reuse solutions to keep cost down, hence the choice of EV battery modules. I will go over some specifics in separate posts.

You and I used the same method of attaching a metal plate to the bottom of the frame to hold the batteries.
