Engineers Create A Strong But Lightweight Isotruss Bike Using Carbon Fibers

Bike frames average about 2.6 pounds!

Engineers used elements of architecture and geometry to create a strong but lightweight triangle-based isotruss bicycle frame. To make a road bike or mountain bike, the isotruss is first wound with carbon fiber using a sheet that holds the tension constant. The engineers then hand-wind Kevlar strands over the isotruss. The process creates a bike with a large strength-to-weight ratio.
