Useful dimension ratios

Seat height feel

About 30 in — a very low seat height for its category. This is a geometry comparison, not a guarantee of rider fit.

Wheelbase / length

68.2% of overall length. This shows how much of the bike’s total length is axle-to-axle distance rather than overhang.

Length beyond wheelbase

About 22 in (560 mm) combined beyond the axle-to-axle distance.

Bounding-box footprint

About 13.6 sq ft (1.27 m²), calculated from listed overall length × width. Useful for rough storage planning.

Clearance / wheelbase

15%. A simple ratio showing listed ground clearance relative to wheelbase.
