I guess for riding on flats a lot less power is needed,.would say up to 4kw for constant speed? Otherwise your 1+kwh battery would ...

Re: Unite/Currie MY1018Z: How many amps do you shove in?

Ive just started experimenting but it does see like this motor loves to eat watts/power. I got the 24v version and hooked it up to 36v li-ion battery. Speed is decent, close to/around 40kmh with not fully charged battery. Had some chain alignment, motor plate fitting issues but now it.seems to.bette...

Friction Drive - kits from Aliexpress. Any Good? Has anyone Tried them?

Hi, there seems to be 3 varieties worth looking at. Most of them come in price ~200 - 400 eur, depending on shipping cost / customs tax, which might be added on top of order. This one seems to be most promising, also boasts 36v and 500W of power: https://www.aliexpress.com/i/32965870432.html -------...

Looking good. Looks like you are progressing battery wise..

Would be interesting to find out how much the final weight is for your scooter with different battery configuration. As you said lifepo will be heavier but how much more?
