Nelson says in a video introducing it.
Im not really sure either, but its definitely not a wheelchair.
Kaylor inspired Nelson to first createThe Rig.
In 2005, Kaylor had an equestrian accident and became paralyzed from the waist down.
She uses a wheelchair and has had to live within the limitations of its design.
It was comfortable and allowed Kaylor to maneuver off the pavement.
Knowing they were on to something, the couple then got to work improving upon the initial design.
The overall goal forThe Rigis that it be capable and affordable.
After all, it was a hole in the market that encouraged them to inventThe Rig.
Shopping for an off-road wheelchair can be frustrating, Nelson writes.
The Rigdoes have manual steering and manual brakes.
It does require upper body strength and hand strength to maneuver, Nelson writes.
Just about as much strength as it takes to operate a normal pedal bike.
Also, coordinating the throttle, brakes, and the steering does require full cognitive and decision-making ability.

The couple spent time refining the design with multiple prototypes.
