For Terns the frame for their lineups are pretty much similar from one model to the next like all the verges and all the links should ride similar in fit and feel to each other. It's the rest of the components that'll change the ride slightly from what i can tell here the gear inches from 25" to 95" should give you a rediculous gearing to even make up those 45 degree san francisco inclines if you ever feel like visiting! and 95" is actually a pretty fast gear that you'll only use on a decline. The only thing i would really change out is the kojaks if your New York streets are as lousy as my Toronto streets strewn with pot holes and stuff and throw some big apples on them to make the ride enjoyable. I cheated though, I ran a big apple in the rear and a kojak in the front to lighten up the bike a bit and still have an ok ride since almost 70+% of your weight is on the rear tire with folding bikes.
