I was going by the last sentence of the article: It comes in two flavors, either single- or three-gear, which cost $699 and $799 respectively. If you go to Yerka's site it does say that "The Yerka model with gears incorporates sealed gears inside the hub which means less service, more reliability and you will be able to shift without pedaling" so the three-speed might have an internal hub gear. But this also clearly implies a model "without gears". And finally at the store page - https://yerka.store/products/yerka-v3?variant=35584723255449 https://yerka.store/products/yerka-v3?variant=35584723255449 - it pretty distinctly gives you an option of "3 speed" and "single speed". And has photos of a bike with one big gear behind the cranks, doesn't even have a chain guard to help keep your pants out of it. No fancy internal gear there.
