My YZ Electric conversion build

[MZIENOWICZ]

Sweet build. Figured I'd show my little build. It's a 72v 60ah 420amp battery with qs138 and ND72890 and 02 wr426 frame. It's pretty fast, comparable to like an older 250. Was thinking of building a new project with a 165 and 96v battery. Something that can sustain some real power. In the background of the pictures are blasters converted to electric. One with qs138 and one with qs165. The blue one with 165 is a beast, way too much power for little blaster frame haha but banshee's are way too expensive and I probably wouldn't want a banshee without the 2 stroke anyway. Would be sac relig. No one cares about blasters lol. I live in lake community and could never have gas powered toys, the neighbors would not be happy but the electric stuff they don't mind. No noise or pollution and no one says anything. It's a win for me, neighbors are happy and I get to build stuff. I used to build race cars, I fabbed chromoly classes. Now I like to build stuff in my garage. Expensive hobby but fun for the whole family

It looks real nice. What cells are you using in your battery. Why did you compromise the frame. I got a 20S12P battery in the same frame with a lot of space left. We build our bike to run on the MX tracks, and I do not modify frames because of big jumps and the stress. Your work looks real good though. The bike looks real clean.
Here is a picture of the YZ250F that I did a few years ago. I put the controllers in the airbox to keep the balance closer to stock.
I am interested in your next build if it is a QS165 60H V3 , but the QS138 70H V3 motors are on the tracks like we use them do get hot at 72V 300-400A. I would like a water cooled bigger motor if we are going to throw more Watts at it. I run a Votol EM260S controller and it will overheat unless we watercool it at 300-400A in the Southwest CA and AZ.

Lol I like the "elegance" of the battery inside the frame. I've road bikes with the battery sticking past the frame and it gets in the way. I don't like it. Personally, form and function on my builds have equal priority. Just a matter of preference I guess. The modifications are properly welded and I have no worries.

They are rs50 cells. I run my bike on the street a lot and wanted the room where the airbox is for a second small "emergency" battery
I wanted that weight lower In the frame. I ride to and from my trails and I know when I've spent my main battery, I have one to get me back home.

I know the 138"s get hot when run hard but i had an extra so i used it. I was also looking at the sotion gts35 water cooled motor but I haven't seen a lot of good reviews on it. The 165 10kw I know is a good motor, the 12kw has to be even better I'm guessing

I'm learning every build. This was my first attempt at 2 wheels. The next one I was going to make more of a dedicated track bike. But they are so much fun on the street and back trails aswell. Wisper quiet and no one bothers me.
