A human being can travel on a bicycle at low to medium speeds of around 10-15 mph (16-24 km/h) using only the power required to walk. PRO-STRAIGHT aims to achieve an average speed of 30 Km/h for exactly the same power... for a speed of 30 km/h almost 75% of effort required is order to overcome aerodynamic drag. Just by knowing this we can realise the importance of reducing the frontal area and setting a better air flow...
