The manual which I found here https://s3.amazonaws.com/assets.scot...N_spark_en.pdf says Shimano E-type FD. The mounting holes are beneath it and you can loosen them and slide it up to meet the bigger ring. It might have a plate that goes around the BB cup, or it might bolt right to the frame, but anyhow those two bolts beneath the cage, part 5 in the diagram below, are the ones. You'll need to put it in low gear and loosen the cable while you do this and hook it up and re-adjust it again afterward.
