The calipers should be industry standard fit. You might consider however, the complete hydraulic setups LUNA sells, but if yours is a folding bike, might not be great. Another great caliper is TRP Spyer, which I have on another bike, and is a great caliper that acts like a hydraulic as it squeezes from both sides. https://www.cxmagazine.com/review-trp-spyre-dual-piston-mechanical-disc-brake/2
EDIT: IT may be the spyke caliper I put on, I'll have to look. You have to match the caliper to the lever type.
