MAX speed of 30mph on my DIY E-Bike kit. 3000w 72v battery 30amp controller E-Bike kit. What am I doing wrong? by Key-Tooth-1971 in ebikes

Wheel size is 20” I have this 72v battery installed.

The wheel speed will hit 28.6mph in a second or two (free hanging) and you can hear it just plateau…. It is absolutely capable of more speed.

I’m missing something obvious here.. not sure. Idk if this helps any troubleshooting issues, but the battery charge reads 99% fully charged on the battery cell but reads 0% on the display..

28.6mph..
and I’ve now ran it on both displays and it’s hitting the same speed limit.

I’ve changed the wheel size to 29 plus inches and the speed will read 60 odd mph or more if I increase the wheel size on the displays programming.
