What is a Quadribent?
The Quadribent is a recumbent vehicle consisting of parallel paired recumbent bicycles that are joined together side-by-side to form a recumbent quad bicycle that two people can ride together.

The Quadribent attaches two EZ-1 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.

It can accommodate additional riders in an optional rumble seat.

Built-In Cargo Platform - NEW
The new Mark 4 version of the Quadribent has a built-in cargo platform (18" x 30").

The Cargo Platform allows you to easily carry things with you: groceries, picnic lunch, perhaps even your dog!

Electric Bicycle Motors
Add an electric motor kit to your EZ-1 Recumbent bicycle. The bicycle motor option provides extra power for climbing hills, accelerating from stop signs, or for when you want to take a break from pedaling.

The Quadribent is 2-seat, side-by-side, human powered vehicle that enables almost anyone to enjoy cycling. The 4-wheeled design maximizes stability and the recumbent position maximizes your seating comfort. Heads-up design eliminates neck, shoulder and hand pain.

Co-Captain steering allows either rider to pilot the vehicle and the dual-drive allows people with different physical abilities to ride together with either rider generating from 0 to 100 percent of the power.

The Quadribent is great for combining an adult rider with a child and/or physically challenged rider. The Quadribent can be separated into two recumbents bikes for “solo” riding and easy transportation however it is not recommended to be done on a regular basis. Most people never separate it.

Quadribent Abstract
(from the Patent)

A recumbent vehicle including parallel paired recumbent bicycles operatively and reversibly joined by a bracing assembly having less than four brace members, is provided.

The parallel paired recumbent bicycles are easily separable, without the need for tools, for individual riding.

A conversion kit for reversibly uniting a pair of recumbent bicycles so as to form a recumbent quad is similarly provided.

The kit generally includes a bracing assembly including a pair of braces, and brackets adapted to reversibly receive portions of the braces therein.

One of the brackets is a front bracket with another of the brackets being a rear bracket.

The front bracket is supported by a front triangle of a diamond frame of the recumbent bicycle, with the rear bracket being supported by a rear triangle of the diamond frame.
