I doubt you’ll hit 75kph with a 36V Motor though. My 52V mid drive would get me to around 40–50kph on a good day, flat terrain, no wind, and pedaling hard. I put it back to 25kph max because riding so fast on a bicycle was too dangerous in my opinion... cars don’t expect you to come so fast, and I was getting too dangerously confident. I was also worried about the consequences should I get in a crash and the bike is investigated to see whether it was legal.
For those interested in diy, the tsdz2 mid drive is a pretty good motor that has a torque sensor and that you can add to most bicycles. There is also an open source alternative firmware for it that’s pretty good. See https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki
