Wheel arches: If the body shape of a velomobile is interrupted by open wheel arches, the laminar stream in this part will be transformed into a turbulent stream, creating a significantly higher aerodynamic drag. This is why the front wheel arches of the Milan are closed to the sides. The openings in the undercarriage are as small as possible, which keeps the amount of rotating air flow escaping very small.

Frontal area: The frontal profile of the Milan has been kept small consequently. This has been achieved by creating individual bulges for all the protruding body parts of the rider (shoulders, head, rotating knees, heels and toes). The bulges for the heels allow to do without openings in the laminar part of the Milan's body.
Nose: The shape of the Milan's nose is designed to reduce the amount of air flowing under the vehicle. This prevents an airflow disruption caused by the profile reduction between the undercarriage and the road.
Undercarriage: The undercarriage is efficently streamlined with a special air guide and flattening.

Head fairing: Because the rider's head usually creates a lot of aerodynamic drag, the Milan sports a head fairing, which "catches" the turbulent stream behind the rider's head and directs it rearward less turbulently. As it needs to have a slightly larger profile than the head to achieve this, it also serves as an excellent rollover protection.
