The pedal sensor on my Babboe e curve needs to be replaced. It is mounted behind the RH crankshaft which needs to be removed to access the pedal sensor. I don't know how to remove the crankshaft. I removed a bolt on the crankshaft which revealed a square post that the crankshaft is mounted on - see picture (please ignore the disgraceful state of the chainring). The crankshaft is firmly mounted on the square post. So how do I remove the RH crankshaft ? Any tips welcome.
