I believe it's the same design as an Ultra Torque road crankset, so a bolt tightened up clockwise from inside the non drive side arm. Obviously there's a tool made to fit that costs ten million dollars, but from memory it's a 10mm allen key fitting. The drive side crank will have a safely circlip that'll need removing before you can extract the crank.
10mm allen key I can manage but how do I remove the circlip? Is it kinda obvious where it sits? (happy to ride across a country but the bike is in another room and I can't be arsed getting up to look)
