Da Vinci Designs hand-builds custom tandem bicycles in Denver using carbon fiber, steel, titanium, and aluminum, each with their patented Independent Coasting System that allows either rider to stop pedaling without affecting the other. The shop offers road, hybrid, and full-suspension mountain tandem models, plus electric-assist versions with Shimano Steps, and designs custom tube specifications for stiffness, strength, and ride characteristics rather than using off-the-shelf components.
