Navigate city streets, cruise the backroads or tackle cobblestones. No matter where you go, let Ethos take you there. Ethos delivers unrivaled ride quality and performance packaged in a strikingly sculpted design that is unlike anything you have ever experienced.

Iso Tech

Iso Tech (Isolation Technology) is a patent pending method of isolating the seat frame from the base frame using vibration damping polymers. These act in unison to significantly reduce vibration that has been linked to pain and fatigue in studies. Also, the casters are no longer attached to the frame you sit on, so vibrations from the casters are not transferred to the footplate and your body.

Whole Body Vibration

Research has shown that whole body vibration from wheelchair use can be linked to pain and fatigue. Iso Tech significantly reduces the vibrations you feel from rolling over everyday surfaces. No other chair can give you a ride like this.

Performance Frame

The base frame has been engineered with incredible rigidity for optimum performance. Its front caster design provides just the right amount of flex to smoothly navigate bumps and cracks. Its also the only rigid frame on the market that lets you independently adjust your wheelbase for increased stability and performance.


Ethos was designed to make optimization easy. You can easily adjust the center of gravity, seat depth and front and rear seat heights to achieve the optimum set up for maximum performance.


Choose from a combination of 21 frame colors, 8 highlights and 8 anodized options. Make it as bright and bold as your personality or make a power statement with a more subtle and sleek design.

Ethos Rider, Wisconsin

"Since receiving my Ethos, I no longer have to get out of my wheelchair to get comfortable. Theres such a good feeling to this chair and as a result I feel less pain in my back at the end of the day."

Karah S.
Ethos Rider, California

"Ive been riding Ethos for 6 months and I love it! After a long day in my old wheelchair my back and hip area was always so sore and my feet were always bouncing off my footplate which would cause a lot of clonus. I dont experience any of that with Ethos. In fact, when I got my Ethos I was still trying to pull my feet back up on the foot plate out of habit, but they were already there! Its amazing. It has significantly reduced my spasticity and improved how I feel throughout the day. Im getting older, Im 46 now. So, to have less pain and more energy makes a huge difference. Im so happy with my Ethos and as a bonus, I loved picking from all the colors options to create something that was really "me". Its so pretty! I get compliments all the time."

Micah Fowler
Actor on ABCs "Speechless"

"Ethos is a game changer. Its so much easier for me to roll this wheelchair. When I use it outside it is so smooth and nice! If you are looking for a new wheelchair you should check out Ethos by Ki. It is the best wheelchair Ive ever owned."

Rick H.
Ethos Rider, California

"My first impression of Ethos was wow! Its new, exciting and rides smoother than any other chair I have been in before. Ethos significantly reduces the vibration I feel from the road and now I come back from rides feeling less fatigued. The vibration damping components of Ethos pays dividends. I also find the design to be incredibly solid. If you werent looking at it, if you just closed your eyes, picked it up, shifted it around and jumped in it - you would never think it has a separate seat and base frame. Trust me, I have ridden pretty much every wheelchair out there, all the way back to the E & J chairs. The difference in how I feel every day is amazing. This is the chair we have all been waiting for."

Paul M.
Ethos Rider, Illinois

"Ethos is the best chair Ive had. After getting in it I quickly experienced the difference from my old chair. The effects from bumps on the sidewalk were nonexistent. Its smooth, quiet and easy to push. Being isolated from the ground really makes a difference in how much smoother the ride is. Also, I think it looks really cool compared to some of the other chairs out there."

Olga F.
ATP, California

"I have three clients with low spinal cord injuries, and they were complaining about pain in their lower lumbar area, spasticity in the lower leg or a combination of both. This was largely caused by vibrations experienced in their previous wheelchairs. I had them try Ethos and each one said the vibration they felt was reduced 30-50% depending on the type of surface they were on. As a result, they all experienced less pain and spasticity. Each client rides an Ethos now and they all say its been a great improvement over their prior chair. Personally, I love working with Ethos, there is so much adjustability that its easy to get the chair just right. Its also so versatile it not only meets the immediate needs of my clients but can adapt to them over time as well."

Melanie R.
M.R., MPT, C/NDT, Amputee Rehab Coordinator, Georgia

"One of my patients experienced a right hip disarticulation, so he uses a wheelchair pretty much all day when hes not using his prosthesis. He needed something with a more rigid frame and hes a heavier guy, so he requires an efficient push to preserve his shoulders. He got an Ethos and immediately noticed the remarkable difference in the stability and efficiency compared to other chairs. He said when he goes outside, he feels like hes gliding across the concrete versus having to push across it. Also, my client and his wife are older, and they loved how easy it was to load into their vehicle. Hes been using Ethos for nearly a year and every time he comes in he shares just how much he loves the chair."
