Rider fit: reaching the ground
The KYMCO People GT 300i has a 810 mm seat; the Vespa ET4 150 sits at 805 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 81 cm for the KYMCO People GT 300i and 81 cm for the Vespa ET4 150.
That makes the Vespa ET4 150 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the KYMCO People GT 300i 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.
