The modeled scores are within three points, so the result does not distinguish a higher-scoring bike. Treat the result as a planning estimate and compare each bike's geometry confidence before a real test sit.
Rider fit: reaching the ground
The NIU XQi3 Street lists a 875 mm seat; the Zero Motorcycles FX lists 881 mm — a 6 mm difference. Seat height is only a first-pass ground-reach input. It does not establish safety or actual foot contact. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change the result.
On seat height alone, the NIU XQi3 Street has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
