It's always nice successfully introducing someone to this long, historied, and very varied franchise. One of us! One of us...!
Anyway yeah there's no direct "Cyborg" trait in S, instead a bunch of other traits say they're cybernetic enhancements in their flavor text. As for the bits, you can use the default ones (range 5 in R, yes, but long range when boosted) or make a custom remote weapon that always has long range. Either way, they cost your actions to move them. I think long range suits them to represent how the Elmeth started out as an assassination sniping weapon. And I think costing actions is a necessity because extra turns in turn-based games are universally broken, so the closest you can do is use them as a combo weapon with "Go, Funnels!".
