Two 20-inch folding bikes, both with 7 speeds and disc brakes, sit at very different points on the price spectrum. One is a used unit listed at a noticeably lower price; the other is a new model with added features. The decision comes down to how much condition matters, what extras you want, and where you'd rather put your budget.
Quick verdict
Choose the USED 20" Folding Bike if you're comfortable with a second-hand unit and want the most affordable way into a 7-speed 20-inch folder. Choose the 20 inch Folding Bike if you want a new bike with an adjustable seat, gear case, and bottom bracket gear box.

Product notes
USED 20" Folding Bike with 7 Speed Gears and Disc Brakes

This is the budget entry point in this matchup. At US$85.00, you get 20-inch wheels, 7 speed gears, and disc brakes in a folding frame. The seller explains the bike is used, returned by a prior buyer, and still seems like a new item, while also cautioning that there may be unseen damage. That's the concrete reason to weigh: a low listed price for the essential commuter spec. The limitation is the used condition and the uncertainty that comes with it-if you can handle minor repairs and inspection, it's a strong value; if you want a no-questions bike, this one asks more of you.
20 inch Folding Bike with 7 Speed Gears Foldable Bicycle Adjustable Seat

The new listing at US$186.77 brings an adjustable seat, a gear case, a bottom bracket gear box, and dual disc brakes. The specification adds a high carbon steel frame, PU seat, 80kg (176lbs) load capacity, and recommended user height above 150cm (59 inches). The reason to choose it is the new condition and the extra features that make adjusting fit easier and protect the gearing. The limitation is the higher listed price-more than you'd pay for the used unit-so you'll want those features and new condition to be worth the gap. For riders who prefer a fresh bike with known specs, this is the more complete package.
Final choice by use case
Pick the USED 20" Folding Bike if your priority is getting into a 7-speed folding bike for the least money and you're ready to handle used-condition quirks. Pick the 20 inch Folding Bike if you want a new bike with adjustable comfort, protected gearing, and the assurance of fresh components.
