Options and Additions
Custom Single Bike Frames

In addition to tandem bicycles, we hand build custom single frames using material from Reynolds, Dedacciai, Columbus, True Temper, Easton and 3/2.5 and 6/4 Titanium. We can build just about anything you can dream up. Take a look around. Creativity does not run short here at da Vinci Designs.

Craftsmanship da Vinci Designs tandem frames are hand crafted with quality materials. We hand-pick every tube from various suppliers and tubing manufactures. Most of our steel tubes are custom made to our exact specifications by Reynolds.

Fit
What good is a great bike if it does not fit? We offer seven unsuspended frame sizes to provide a perfect fit for most teams, and custom frames for those who need it. Our road and unsuspended offroad frames are interchangeable; the angles and tire clearance are the same. The differences between our road and offroad frames are in the height of the top tube. Short legs and long torso, or long legs and short torso? No problem. We'll be sure to fit you.

Ride
Aside from the benefits of the Independent Coasting, you will find that da Vinci Designs tandems are the most comfortable, fast, precise, agile, and stable tandems you will experience. Customers tell us their da Vinci rides more like a single than any other tandem they have ridden. We attribute the ride quality to the race proven geometry, large diameter tubing, careful placement, laser straight alignment and flawless construction.
