   This led several velomobile designers to re-consider 4 wheels for aerodynamic velomobiles—despite the inherent drag losses of 4 wheels compared to three. Velomobiles.nl claims for a given width, four wheels offer 40% higher cornering stability than a tadpole tricycle of similar width and center of gravity. [8]

These bicycles had solid rubber tires and as a consequence the only shock ...
