Rider fit: reaching the ground
The CAKE Osa+ has a 795 mm seat; the Sondors Metacycle sits at 800 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 80 cm for the CAKE Osa+ and 80 cm for the Sondors Metacycle.
That makes the CAKE Osa+ the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Sondors Metacycle gives taller riders more legroom and a more open knee bend. Load your own height and inseam into the simulator to see exactly how each one fits you.
