It is known that maximum braking occurs when the front brake is applied so hard that the rear wheel is just about to lift off. Skilled cyclists use the front brake alone probably 95% of the time. However, improperly modulating the force applied on the front brake will bring the bike to a sudden stop, rider and bicycle's weight shifts to the front thus generating a momentum (force) that will send the rider "sailing" forward over the handlebars and eventually the bike will flip. The second case scenario a bicycle hits a end parking concrete barriere at 15km/h. Chances are the bicycle and rider will flip over. Q1): Does anyone know what is the name of the generated force ( that throws you over the handlebars). Q2): Based on speed, bike/rider mass-height how can this force be calculated. Any links?
