Davidson Modal
A travel bike that folds and toggles between single, fixed, and geared modes.

The Modal Bicycle Concept 
The concept of the modal travel bike is to have a bike that is thoughtfully designed and equipped so that it could be run as a regular road bike or quickly converted into a single-speed road bike with minimal fuss and fit into an airline-friendly case for travel.

Single Mode Details
For the Modal to work, it’s built as a road bike with two sets of bars: one has shifters and other just brakes. I’m simply removing the derailleur, releasing the chain master link, swapping out the Paragon, changing the bar, and connecting the cable stops. After a few adjustments, the bike is ready to ride. The beauty of a single speed when traveling is fast rear wheel in and out. There’s also very little to break in transit.
