Hey there guys!
Been a lurker for the longest of times, and decided to post a build log of my electric enduro brat build.
Short introduction, i'm from the Philippines and decided to start retrofitting gas bikes to awesome all-electric.
I work with a small team, in a very nitty-gritty compact garage. :D

Nomad
Basebike: Rusi KRZ200 (chinese steel-framed dirt bike.)
Motor: HPM-10K (Golden motor 10kw, watercooled.)
Controller: Asi BAC8000
Batteries: Samsung 25r 20s 35p
Tires: 120/90-18 rear, 90/90-21 front
Sprockets: 12t front, 90t rear
Total system cost: around $6-7k++

Presently set to around 450a battery, 800phase and topping off at 120kph. No real sense to go any faster, given the road and traffic conditions here.
BUILD LOG.jpg

1. Bought the frame around january, roughly around $250 for the entire thing with papers to my name.

2. Got some mild steel, welded it to the frame for a mock-up mount with my other old and busted gm10kw that blew up from spinning up too fast. :lol:

3. Using CAD (Cardboard aided design :p ) a rough mockup of how the batteries are going to be fit. In my bikes case, it had to be three separate modules working as one in order to maximize the space, making all 700 cells fit.

4. As i've said, nitty-gritty lmao. While waiting for the samsung 25r's to arrive, we're using what cells we have to get the overall pack configuration in shape.

5. Cells are finally here.

6. My battery specialist, Alexander working a blur in our awesome secret laboratory that's totally not a fire hazard of a place. Cells are glued, welded with a k-welder. Nickel strips and copper busbars. Kapton, waterpoofing cloth and then resin painted over it.

7. The stock bike had horrid 16"/18" wheels, which was much too small for my size. I'm relatively tall for an asian, being 6'0 feet flat. Our local laceman is used to our kooky projects, setting up mxus', qs205 and qs273's with no problem. Spokes are and labor generally don't go above $10 per wheel.

8. Bike's starting to look proper. Also, if you've noticed i've changed the stock chinesium upside-down suspension to an old yamaha tenere' xtz 660 96' model a good friend of mine sent my way.

9. Sprocket is installed, and chained up. This is a local #40 industrial sprocket sold in the dark alleyways of my country. Works great with a 428 chain. Chain guard was later installed.

10. Here the body has been repainted to matte black, and the golden motor 10kw mounted.

11. Main "Africa" shaped battery module is slid in sideways into the belly, while the two smaller modular packs sit on top of it. The water cooling inlets couldn't be used do to it hitting the pack, so I just filled it with coolant, sealed it, and used forced air cooling later on. Works great.

12. Cutting up some stainless sheets of adequate thickness and a little persuasion with a rubber mallet, and the battery guard is made. The skidplate underneath is still a work in progress. :roll:

13. A friend of mine offered up to re upholster my seat for $30, and I requested a classic brown faux-leather finish, with a darker pattern in the middle for a two-tone look.

14. Here's the bike with more paint and accessories fitted. All its 12v systems (lights, horn, keyless alarm) are powered by common 10a pull-down converters. I've got 4 in parallel.

15. 130w osram led headlight. I love this thing. Nice, clean beam and great brightness.

16. My girlfriend gifted me with a laser cut decal that fits in this nice little spot on the motor. You will ride eternal, shiny and chrome. (also, the little super fans are installed. Don't be fooled by their size! They blow a lot of air, comparable to hotel hair dryers.)

17. Body lighting for better visibility, while keeping thematic to my red/black colors.

18. Fast forward a week or so later, I brought the bike to a local flat-track funrace. Nomad is sitting alongside his other e-buddies. Scrambler on the left is a qs 273 tourer build, so is the green bling machine and the desert scrambler peeking on the right.

19. Powder. Cough.

20. I'd like to thank evolution gts for the asi controller, hence the stickers to represent. Also, you can see the xt90 charging connectors by the side, for easy access.

21. Alexander on a bafang powered emtb and I on Nomad taking on custom gas bikes in the flat track race.
I won first, he won third on the first round. We both effed up on the finals due to slipping on the same spot, hahaha. :lol: :lol: :lol:

Less than a week ago, managed to procure some CRF 250 08' model forks. Actually, the entire front set. It handles bumps and overall road harshness MUCH BETTER.

Also, a peek as to what kind of road conditions prevail here in the philippines. Slicks ain't gonna cut it here.

Bad ass build! Great job!
 
Hey Brother. I promise to have a better battery station. Sooner than you think ;) no more building batteries on a HOLY couch ahahah patched with a GM stator lol
 
Awesome build, fast and it looks fantastic, and you built it on a pretty tight budget which takes a lot of commitment. Glad you are happy with the result :bolt: :bigthumb: :bolt:
