Rider fit: reaching the ground
The Brammo Empulse R has a 800 mm seat; the CAKE Osa+ sits at 795 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 Brammo Empulse R and 80 cm for the CAKE Osa+.
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 Brammo Empulse R 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.
