A friend wants her very old throttle-only Ezee bike converted with a proper PAS and a LCD (ideally).
I tried a couple of KT controllers, which both worked perfectly, but backwards. when I alter the wiring to go forwards, the motor runs too fast, like 50 mph, with both controllers. I tried every combination, which gives three that run perfectly backwards, three that go over-speed and three that give 10 mph smooth forward with high current.
Just for testing, I tried a KU93 controller that will run anything, but it went backwards too. I switched the wires and then it ran too fast. I pulled the hall plug to make it run sensorless, which made it run perfectly, but the KU93 only has one PAS level- maximum power, which is not very user-friendly.
I can only guess that the hall sequence isn't symmetrical, so reversing the wires doesn't work.
Does anybody know a controller with proper PAS function that will work with the Ezee motor. She doesn't want to spend a lot of money. I told her £80 for a KT controller, LCD and motor cable.
Has anybody got any other ideas.
