Technical Praise for the Bezerra Stepper Mechanism
Mr. Bezerra first put his design to clinical testing in 1995, when Associated Testing Laboratories (ATL, a Wayne, NJ-based company) performed physical analyses on an early prototype of a bicycle fitted with the Stepper Mechanism against another bike with a standard crank mechanism. The bikes were subjected to bicycle kinematics, which is the study of force applied to the pedal system. They were also tested for force transmission using a 50-lb. weight applied to the pedal system. As noted by the report, a consistent force was obtained throughout the cycling force by the Stepper Mechanism, as opposed to the "come and go" nature of the conventional bicycle's measure of force.
The following quotes are lifted directly from ATL's findings (available as part of the Company's Business Plan):
• "In a complete revolution, test results revealed the conventional bike lagged behind, traveling only 386 inches, compared to 629 inches by the Stepper Bike. And, because pumping up and down is [a] more efficient motion than circling round and round, in the time that it takes to complete one pedal revolution on a conventional bike, a cyclist can achieve more than 3 pedal strokes on the stepper. As a result, the stepper cyclist can travel a greater distance with equal pedaling effort."
• "[T]he Stepper Bike's smooth pumping action displayed an almost uniform, wave-like distribution of force. Technical data supports that the Stepper Bike is much more efficient with 90% force being transmitted to the rear wheel, while the conventional bike falls behind with only 63%..."
• "A remarkable feature of the Stepper Bike's propulsion mechanism is that it is so far advanced, it has the ability to be adjusted to accommodate any degree of desired force...This fulfills a broad spectrum of consumer needs."
Sweet Spot Studios provided another analysis of the Bezerra Stepper design against a conventional bicycle, which found that a significant increase in force was delivered directly to the chain by the Bezerra design over the conventional bicycle.
The US Cycling Federation backed the real-world application of the Bezerra Stepper Mechanism to racing bicycles all the way back in 1995, when it approved the Bezerra design for use in mass-start races under its jurisdiction.
