With a frame that’s lighter, more aerodynamic and less breakable than many top-of the-line counterparts, a new bicycle created by a team of Brigham Young University engineers may soon change the face of cycling. A second team has created the “Y-Flex,” a weight simulation fitness machine coming soon to a home gym near you.

       

Made from carbon fiber intertwined with Kevlar string, the bike’s frame employs civil engineering professor David W. Jensen’s IsoTruss — a cage-like, open tubular lattice that optimizes the inherent strength of reinforcing pyramids and triangles.

“The team’s goal was to shrink the IsoTruss structure, which has been proven to work well for large-scale applications, from between 5 to 18 inches to about 1 inch in diameter,” said Jensen. “Everybody involved has done a great job of accomplishing just that.”
