Pendleton Somerby e bike fault

[Goog]

Hi,
I have a Pendleton Somerby e bike bought second hand.
The other day there was sudden loss of power then the fault disappeared for a day.
It has now come back, power is in surges and stops all together after about 4 mph.

Halfords have confirmed the crank sensor is still working but can't say for sure if fault lies with the ECU and or the motor.
Their workshop is fully booked for a fortnight, then after proper diagnosis there is a further week's wait for parts.

Obviously I will now go down the route of employing a local independent e bike repairer.

Any ideas anyone on where the fault lies?



Any ideas anyone

Check that the motor connector is in all the way to the line, not just in tight.
