What's your budget? Not gonna be cheap to do that, especially for the battery.
Just some thougths so you have an idea what you may need at those kinds of speeds and distances.
Keep in mind everything below is approximations; you'd have to figure out your own actual numbers to work from, based on your choices for motor, controller, battery type, bike type, terrain, riding style, etc.
At a guess, you'll probably need around 4Kwh of battery for 60km at 90km/h, depending on your actual power usage (which depends on terrain (hills), stops/starts, vehicle+rider weight, weather (wind), etc.). Some of the motorcycles going those speeds average arond 120wh/mile. (
At a guess, based on the two 2kwh packs I have, the battery itself will be around 50-60lbs+ depending on what cells it's made from and how it's built/packaged, and about the same volume as a good stack of hardback books, or nearly a 10gallon fish tank.
What voltage you want will be determined by how fast you need to go vs the motor's kV and any gearing between it and the road. Then the kwh you need divided by the voltage you need gives you the Ah of the pack.
If you want it to acclerate quickly, you may need around 4-8Kw (or more) of power out of the battery. Again, depends on stuff like vehicle+rider weight, etc.
What kind of battery you get will be determined by how much power you need out of it, and the size of the battery you can fit on the bike. If you need 8Kw of power out of it, and its' a 4kwh pack, then it has to support a c-rate of 2c, without much voltage sag or heating. If you need 16kw of power out of it, the same pack has to support 4c. If you only need 4kw out of it, it only has to do 1c.
So, just as in your other thread we tried to help in, you should look at this thread
https://endless-sphere.com/forums/viewtopic.php?f=3&t=66302
and then copy the first posts's questions to a reply in your thread here, along with your answers to those questions.
That will help us help you figure out what you *really* need, and get you building and riding what you actually would enjoy riding.
