electric / default rider 183 cm
NIU FQi 500 vs VMoto CPx Explorer ergonomics
NIU FQi 500 and VMoto CPx Explorer have modeled posture scores within three points for the 183 cm default rider. Treat this as a planning estimate; posture preference, data confidence, and a real test sit still matter.

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 FQi 500 lists a 760 mm seat; the VMoto CPx Explorer lists 760 mm, within a few millimetres of each other. 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.
