I have a 4T in a 17" and it is a rip-you off bike almost and very responsive, so much so I consider the 3T.. for the RPM. You do NOT go max throttle anywhere under 40mph.. and even then it will bring the front up @ 25-35 if you really want it to.. until it hits the kV limit and the current drops ( back EMF limit)... From what I ganther.
I have a 72v Kelly, 8kW rated. 350A phase... I was afraid the 5T would be to slow... and the 4T only gets 52mph loaded.
The Kelly peaks at 18kW. The battery is very power dense, based on the volume. Relative. This bike will put you through a wall easily, from a meter away... if is torky, 134lbs, Eleek. Two shunts for data acquisition.
Perhaps the battery cannot do the full current. I also vote for a larger controller.
Is there any current measuring device inline?
4 - 500 Phase A on this motor must be nuts, jbjork. Perhaps we will be able to compare results some day,
Yes a 72100 will not cut it. This motor did not get warm @ 17.7kW up a hill, on my 8kW Kelly.
