Hey all,
I built an electric onda board based off info I've scraped off the site here over the years, and I often commute on a BBS02-driven hardtail 29er. I primarily ride a long, low Honda Ruckus as a commuter vehicle, and I'm planning on building an EV ruckus. A few years ago I built a 170cc ruckus in my living room - it turned out quite nice in the end. Everything on the bike came in parts and got put together over the course of a few months.
Here's my plan - I've done a smidgeon of research, and I've decided I want to keep the most 'stock' look as I can. Rather than swapping in a swingarm and a hub motor, I want to mount something like an ME0708 right where the stock motor was. I have a shapeoko3 dialed in for aluminum and don't think I'll have much trouble fabricating a plate to mount the ME0709 on the stock swingarm. I'll ditch the belt, retain the stock final drive gearset, remove the centrifugal clutch, and direct drive from the output shaft of the ME0709 to, say, a 12 toothed sprocket, then to the final drive shaft something between 60 and 70 teeth, whatever fits and works well.
Here's the inside of the swingarm in question:
The hole at the far left is where the motor mounts, the swingarm sits on the left side of the bike. At the far right is the centrifugal clutch, and behind it is the final drive. The final drive's output axle will mount to a stock wheel. I think with the CVT cover on, I'll be able to have the sprockets and chain invisible. Alternatively I could mount the variator on the output of the motor, but I can't imagine the stock CVT is going to be beneficial versus direct drive.
Before I start buying expensive parts, I wanted to make sure I'm 1) not off my rocker and 2) on the right track parts-wise.
from electricmotorsport, as a kit for simplicity's sake

Does this sound alright? Right now I can hit mid-50s with my 66.6cc motor, I'd like to stay around there speed-wise, though I rarely cruise above 45. Range isn't a major consideration, though I'll fit as many cells where the stock gas tank goes (floorboard in the pics).
Anyone have any input? I ran this all past the ruckus community but nobody there's ever done anything like this before.

8) The Gigavac GX14 48V looks a lot smaller than the Albright, it might be easier to mount somewhere hidden on the Ruckus. You say ''fuse block''? Is that for the 12V system? Here's something that looks awesome, it will definitively go in my next project.
