    Now I have found the error. The cable connector to the motor sitting on the fork were not fully insulated. There was leakage between the power cables. Cutting it and replacing the wiring did the trick. The old controller did not work either, so it probably broke in the process. Now my hall...

    Already done that, but that is to check the controller. Now I am measuring on a disconnected motor, no controller in the loop.

    The new controller has arrived and it didn't help. The exact same behaviour, just a couple of pushes than rotates the wheel a couple of degrees. Must be the motor that is malfunctioning. Can I check it in some easy way? Measured the resistance between the three phase connectors from the motor...

    Great offer, thanks! But the problem is that I am not based in the UK. As a swede doing business with UK based firms nowadays I have the toll regulations to factor in. As a minimum the Swedish mail will add around 10$ for their 'help' with declaring VAT for the goods. Then the VAT added is...

    I wouldn't call it that the motor spins up, it is only revving really slow. Probably about 2-3 rpm. And not in a smooth way, more moving/jumping a couple of degrees and then waits for some time before jumping to the next angle. Maybe around three "jumps" per second. Yes the PAS works, that is...

    I have measured the resistance between the three power wires and power, both positive and negative. The result were if I remember correctly, roughly 5 kohm on one side (negative) and infinate on the positive side. I dont know if this is a test on both the high and low side? I know...

    The LCD is non existant, see pic. The controller is flashing with a red led inside. I guess you can see the red light shining throgh where the red/yellow/black cables are entering the controller. The flashing is about one second on and one second off. The battery is most likely healthy and...

    How do I check the MOSFETs other than doing the measurement I already performed?

    Just buy a new controller and test if it works? Or do you have any troubleshooting tips except the MOSFET test that I already tested? Does the speed sensor matter? If it is unplugged, it will just make the bike go faster?

    You are wrong ,;) the manufacturing date of the PCB is week 49 2018. There is no display, just a push button with some leds on. Looking at a similar bike, it has got the same 'display', so I guess/hope it is compatible. Is the controller sensored? That I don't know, how do I check it?

    6: Three for power and three for the speed hall sensor.

    No, the board is probably a generic board. That is why you see the three slots for rotational hall sensors. There are only three connected slots out of 6 on the board. The motor is wired with three thicker cables and then the speed sensor is wired by three thin cables. When there is three...

    Hi, I have bought an used cheap china bike, named Epoque Lynx. The retailer have gone out of business so there is no luck getting help there. The motor is only rotationg the wheel really slowly and in short 'steps'. No assistance at all. I have checked the MOSFETS and they seem ok, according...
