to remove the left pedal and crank you need to remove the retaining nut from the crank, then use a crank extractor to pull the crank off. A crank extractor is quite cheap, but any bike shop could do this for you in a couple of minutes. It would also pay to enclose the exposed shaft.
As Ray1 suggested
In case needed I have fitted a single bike pedal toe strap to the left pedal so I can pedal to a degree
One small point, it would also pay to check and see if the motor is supported with a bracket or cable tie. For reference, click on 'RESOURCES' at the top of the page, go to 'Miscellaneous', and there you will find 'Motor Bracket'. Sorry no photo available of the cable ties, but maybe Chas can come up with one.
The reason for this mod is that when the motor has to supply high torque, e.g. when starting, it has a tendency to twist. This twisting can result in the belt slipping, which in due course results in radical wear in the belt and the sprocket.
Sorry this is a bit long winded, but maybe of some help to you.
All the best.
