The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Tomos Standard 25 has a 810 mm seat; the Yamaha Y15ZR sits at 845 mm — a 35 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 Tomos Standard 25 and 85 cm for the Yamaha Y15ZR.
That makes the Tomos Standard 25 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Yamaha Y15ZR 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.
