electric / default rider 183 cm
Brammo Empulse R vs Ultraviolette F77 Mach 2 ergonomics
Brammo Empulse R and Ultraviolette F77 Mach 2 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 Brammo Empulse R lists a 800 mm seat; the Ultraviolette F77 Mach 2 lists 800 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.
