Hi,
I'm starting to convert my Puch R50 to electric
I want a top speed of +80 Km/h and a range of +40km.
I brought the QS 138 70h v3 + Votol EM-150 kit.
The battery I have some doubts about it. For now, I want to buy a battery already made to keep it simple. I was thinking to buy a 72V 30Ah with 60A BMS(https://a.aliexpress.com/_mNtm1Vu) but all the posts I see use custom batteries with much higher BMS(150/200/250/300A).
For the sprocket ratio, I see this 39T 428 sprocket(https://www.amazon.de/-/en/Sprocket-Teeth-Pitch-Chain-Z%C3%BCndapp/dp/B07QN6WKK3) that fits on the position of the original 35T 415(I think) and use the 15T 428 sprocket that came with the QS motor. Some doubts about the top speed, what is the best way to calculate? The wheel is 12"
I need your help to solve my doubts
