PowerCranks™ are the world’s first independent bicycle cranks designed to accelerate your potential in any sport.
PowerCranks™ can improve your performance if you depend on your legs for speed and power.
PowerCranks™ can increase your benefit from exercise for the same amount of time invested if your workouts suffer from time constraints.
For certain lower extremity injuries, PowerCranks™ force the optimum rehabilitation for the injured leg.
PowerCranks™ trains the major hip flexor and hamstring muscles as aerobic power machines while enhancing unconscious coordination ability.
PowerCranks™ integrates a one-way clutch in each crank-arm of your bicycle or stationary bike. This patented modification changes the cranks from being fixed to each other at 180º (as are regular cranks), to being independent from one another. Each leg can drive the bicycle but one leg cannot assist the other. Effectively, with PowerCranks™ the rider is doing one-legged pedaling with both legs simultaneously.
This simple modification benefits the PowerCranks™ user:
Fully train the hip flexors and hamstring muscles that are otherwise difficult to train
Enable neuromuscular changes that improve cycling efficiency and running form
Balance the muscle effort and improve the coordination in lower extremities and core which can lower the risk of injury
Improve running ability while training in a non-impact environment
Act as a rehabilitation tool since the good leg cannot assist the bad leg (thereby utilizing all the major muscle groups in the legs).
Nothing beats a PowerCranks™ workout! Twice as many muscles exercised results in increased basal metabolic rate compared to standard biking or spinning
Why do PowerCranks have such a revolutionary effect?
As children, we learn how to pedal our tricycles and bicycles by pushing on the downstroke and relaxing on the upstroke. As we grow older, we learn to push harder on the downstroke and unweight our feet on the upstroke. The reality is that, without PowerCranks™ training, we still leave back-pressure on the upstroke. This happens because the cranks are fixed together.
Eventually, we may purchase toe-clips or clipless pedals to allow us to “pull up” on the upstroke. Even so, do we actually pull-up and achieve proper mechanics in our pedal stroke? Virtually all of us do not… we still under-utilize our leg muscles. We may use clipless pedals, but it does not mean we have changed our ingrained pedal stroke.
