We have developed a revolutionary, patent-pending technology called “the stepper mechanism,” which produces about 3:1 advantage upon takeoff and going up hills, thereby significantly increasing performance. The extra force it creates (a nearly three-to-one advantage over the conventional bicycle in all force-related aspects), coupled with its ergonomic advantages, could potentially render the conv
entional rotary crank obsolete. Moreover, the mechanism incorporates only main components, each having its own subset of parts—a pulley, small additional sprocket, and a chain. We now seeks to license this technology to bicycle manufacturers, initially to the high-end sector and, once established, to the middle- and low-end sectors. Bezerra Corporation’s revolutionary cycle feature is a pedal-crank mechanism, referred to in this plan as the stepper mechanism. The mechanism operates in a vertical, up- and-down, “stepper” motion, and is designed to replace the 6.0 to 7.5 conventional rotary crank arm. The stepper mechanism’s crank arm is nearly three times longer than a conventional rotary crank arm, providing more efficient transmission of force to the drive wheel. Causal cyclists will experience greater ease of use. Conventional rotary pedal configurations are limited by “dead zones” occurring at the 12 o’clock and 6 o’clock pedal positions, where almost no force is transmitted from pedal to back wheel. If the cyclist attempts to stand with his/her weight on the pedal for an entire half cycle, s/he would use only an average of only 63% of the force necessary to push the bicycle forward. This is problematic when cycling, because the bicycle “jumps” forward when the pedal reaches 3 o’clock, and then slows as the cyclist strains to bring the other pedal past the dead zone. The Bezerra technology eliminates the “dead zone” by replacing the cycling pedal motion with a more linear, stepper motion, which utilizes an average of 93% or more of the cyclist’s force. From the standpoint of performance, the stepper motion is significantly more efficient. Biomechanically, the motion is smooth and less fatiguing to the rider, and it does not position his or her legs and knees at the awkward angles that are inherent with a conventional cycling motion. In addition, the cyclist can achieve double the RPM and sustain and maintain the RPM for many hours. Also, the motion transfer mechanism has a 20:1 advantage upon takeoff and going up hills.
