The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Yamaha Jog CE50 has a 690 mm seat; the Yamaha Morphous sits at 655 mm — a 35 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 69 cm for the Yamaha Jog CE50 and 66 cm for the Yamaha Morphous.
That makes the Yamaha Morphous 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 Jog CE50 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.
