That Outperforms a Pickup Truck
A Chair that Supports 550 lbs Safely is Doing Something no 50 lb Folding Chair Can Do. Here's the Math — Compared to Things You Already Trust Every Day.
It's Time to Get Your Life Back.
We Built the Ark550® for People who've been Told to Stay Home one too Many Times. Told to Skip the Trip. Told the World wasn't Made for Them. We Disagree. The Beach. The Mountains. The Grandkids' Birthdays. The Quiet Moments Outside your Front Door. They're all Still There — and they've Been Waiting for You.
Every inch of the Ark550® has been carefully engineered with real-world experience in mind. As wheelchair users ourselves, we rigorously test, refine, and test again—ensuring it’s portable, comfortable, and powerful enough to tackle obstacles that leave traditional scooters and other wheelchairs stuck. Whether it’s curbs, gravel, or rough terrain, the Ark® is built to forget the forecast and carry you to freedom, rain or shine.
