The EZ Quadribent

​What is a Quadribent?

The EZ Quadribent is a two-seat, side-by-side, human powered vehicle that enables almost anyone to enjoy cycling.

The EZ Quadribent attaches two semi-recumbent bikes to make a four wheel, side-by-side "Sociable Tandem" with independent gearing and pedaling. The recumbents can be detached for solo use.

The EZ Quadribent side-by-side bike is designed for comfort, stability, easy and efficient riding.
