I would like it classed as a moped to keep costs down, so 50kmph. Home to work is 10km, so 20km return each day, urban only. I have seen Aliexpress kits for a reasonable price, 1000W or so? I have read they can be a bit gutless and want to keep up with traffic at a green light. No real idea on if this is a suitable power rating. I have also been to Haynes Engineering and found a few options in scrapped forklifts for motors (1-2kw). I have 300 18650 cells, but would probably grab the best 150 or so and buy extras to make up the right voltage and cell C rating to match the motor. Perfect, thanks! You're right, I shouldn't have jumped straight to a project subforum. My apologies.

I am looking to convert something like a Honda C50 or Yamaha V50 to electric, and I am looking for advice. If I want to ride it on the road as a commuter to work, I'm guessing i'll need compliance certificate before registration? I'm hoping @cletus is happy to chime in because he would be my closest LA class certifier. I've had a read through the LVVT docs and as long as it stays under 50km/h and under 60 volts it should be ok? Anything else to design in? I have a bunch of lithium batteries that I can build into a right-sized pack, and still need to decide if I use a hub motor or a centrally mounted one. But before I go spending any money on a donor bike or motor, what do I need to know? NZTA says a moped needs to be registered and entry certified. Is it a big deal to re-register if I find a de-registered donor? Working examples can get quite pricey. Thanks!
