I can not set PAS to assist pedalling. Pedals is more like a throttle

[Jai134]

I use Bluetooth and an android mobile phone and I can not get my PAS settings to work well. If I change ratio to 100 it kicks in on level 2 but not 1. If I lover it to 60 it works at level 3 but not 2 and 1. When it kicks in it accelerates like crazy up to approximately 20 km/h and I need to pedal very slow to keep a constant speed. I just control the speed without adding any pressure to the pedals. There is no correlation between pedaling and motor speed except for starting the motor.
Ratio is set to 100
Acceleration to 30
Current to 15
I havent changed anything else except for throttle which is "close". That is still working though.

I could really need an answer because I don't understand if it works as supposed or not. PAS level 1 does not work at all even with Ratio set to 100. If I set PAS Ratio to 70, level 2 starts to work but then the bike accelerates to 25km. If I want to keep a lower pace I have to peddle very slowly and without resistance. It is just useless like this!
I have a Magic Pie 5, pedelec from GM and a single speed bike with Gates Carbon Drive 60 teeth in front and 22 in the back.

The GM pedelec is very poor as it only senses the pedal rpm not the torque being applied. As your gearing is fixed, fitting a 12 pole magnet ring should enable the PAS to work on the level 1 setting but I don't think it would make much difference to the PAS operation.

I had to stop using the pedelec on my Magic Pie equipped "Wheelie Machine" and just use the thumb throttle because the pedelec was way too sensitive.



If I needed more assistance from the motor when pedalling uphill, I would have to change down to a lower gear. Unfortunately, the sudden increase in the pedal rpm caused too much power to be delivered to the motor, resulting in the front wheel lifting off the ground completely.
Unfortunately, to achieve a decent pedelec operation you would need to install a torque sensing bottom bracket, preferably in combination with a Cycle Analyst to control the current output to provide a true "torque controlled" pedal assistance.
