yo i got a question; u said your motors 3000w, battery pack is what 36v 32a for about 1200wh. Sooooo how can u get the full 3000watts from the motor. Wouldnt u need a 72v 40ah battery pack, otherwise just get a 2kw motor instead or something. I am just wondering b/c i am thinking bout building an ebike sometimes and am curious about matching battery size with motor. LIKE i found a 5kw motor hub from alibaba for 200 dollars. Then I would need a 96v 50ah battery to get the full potential of the motor, Right? Otherwise lets say i used a 72v 40ah which is 3kw, then the motor would only draw 3kw and run 60% as fast (3000/5000).
Yeah, it was at 36V for a while but then I put the two battery packs in series to get a 72V 16aH pack. I've done like 45 mph and it still wanted to pull hard but I don't know man that was really shady on a Walmart bike and no helmet. I was on a 50 mph road and literally a line of cars was in awe following me as I smoked them off the line. Actually, gotta be careful with that too so they dont have some nagging nancy call the cops on you.
When you decide between a hub and mid drive, I think it all comes down to if you want to ride your bike somewhat like a normal bike and maintenance. I have a 500W and have had a 1000W gearless hub motor and I would tell you I felt the coggin on the 1000W. I can't imagine what a 5000W rear hub motor cogging is going to be like. The cyclone is like 12 lbs or something and the 500W rear hub is like twice that for 1/6th the power. But, then the gearless hub motors are so maintenance free just make sure you got a damn good torque arm on both sides of the bike for 3000W+. My 500W not one issue at all. The Cyclone destroyed one of my cassettes LOL.
