The inventor of the 4 Strike Bike is the Dutch Lex van Stekelenburg. He has worked for many years as surgeon. The idea of the 4 Strike Bike arose from physical complaints:
“I developed troublesome back and shoulder complaints from years of performing lengthy surgical operations while standing with a bent and crooked posture. To recover from and prevent these problems, I came up with the idea of this bike. I then designed and built the first bike and began to use the 4 Strike Bike successfully. Over the past 5 years I have experimented with several prototypes that hundreds of enthusiastic people have now cycled on.
As slow walkers we pedestrians can’t do without our bikes and cycling has become a sort of ‘second gear’. If we don’t allow a rigid handlebar to suppress the natural feeling of wanting to move our arms together with our legs, but enable them to cycle as well, then we can shift into a ‘third gear’. We have now constructed a bike that you can cycle almost as if you were four-legged, assuming a more horizontal position and with harmonious movement along the shoulder and pelvic girdle. As well as steering, the hands now move with the feet in an alternate parallel pedalling movement using all 4 limbs to create more speed.
With the use of more muscle power from the combined use of both upper and lower body, more muscular work is performed and the effort more equally distributed; this is healthier for heart, better for aerating the lungs and prevents undercooling of the upper body in rain and cold. You’ll have more fun on this revolutionary new bike.”
The bike is produced by Minq Engineering B.V. in Lichtenvoorde
