WTB Quadricycle, quadracycle, 2-person side-by-side 4-wheel tandem bicycle
 

I am looking for a 2-person, side-by-side, 4-wheel bike.

Bikes in this category include:
EZ Quadribent by blackbirdbikes.com
Lightfoot Cycles Duo, Duette, or Microcar
Pacific Cycles 2-Rider

I do not want a heavy surrey like the Rhoades Car. I appreciate quality bicycles and would like a quadricycle similar in quality and weight to two recumbent bikes.

The purpose is to be able to ride with elderly or slightly disabled people.

I live in Indiana.

Thank you,
Fritz
