Features of the rugged wheelchair designed at MIT:

The GRIT Freedom Chair


We know purchasing adaptive equipment can be a serious investment, so our team works hard to offer the most versatile, rugged wheelchair on the market to make your investment worthwhile.

GRIT spent years prototyping the design of the Freedom Chair to make sure it was best suited to help those who matter most: Our riders. We arranged hundreds of face-to-face demos with wheelchair riders around the world and used their feedback to craft our products and our company mission. From the implementation of components and accessories to the relationships we build with our customers, the GRIT team is committed to doing all we can to help you get outside, over and over again.

The result? An all-terrain and manual rugged wheelchair ready to take you just about anywhere. Hit the trails, an obstacle course race, a grassy park, the beach, or anyplace you can enjoy independence or quality time with the people you love. Below, we’ll discuss some of the key features of the Freedom Chair.

If at any point you have questions, need clarification, or would like to talk to a team member about getting a Freedom Chair of your very own, give us a call! 877-345-4748.

A rugged wheelchair, easier to push

Less shoulder strain. More fun.

Our MIT-designed patented lever drive is tested to be about twice as physically efficient than a regular wheelchair. This design is not only more efficient; it is far better suited for safely navigating difficult terrains. We use the properties of leverage to give you the same benefits of shifting gears on a bike. This means that the GRIT Freedom Chair lets you cruise faster than walking speed on smooth ground, but also gives you the power you need to climb over hills and roll through grass, dirt, and sand.


King of the hill

Grabbing the tops of the levers gives you a lot of torque, making it easy to overcome obstacles.


Win the race

Grabbing the bottoms of the levers lets you cruise efficiently on sidewalks, bike paths, and roads.


Take it anywhere 

With lots of quick-release parts, the GRIT Freedom Chair disassembles to pack up easily

The GRIT Freedom Chair is the first rugged wheelchair that is just as easy to take to the trail as it is to use on the trail. The wheels, seat back, and footrest can all be removed with quick-release buttons, enabling the GRIT Freedom Chair to fit into the trunk of a small car.

We designed the chair to be disassembled in less than one minute—depending on your vehicle, you may not need to remove all of the parts, but the more you remove, the lighter your load becomes. Compare this to folding chairs, which collapse but still require you to lift to full weight of the chair, or to other all-terrain devices, which may not disassemble or collapse at all.

When fully disassembled, the heaviest part of this rugged wheelchair weighs just 25 pounds.


A mountain bike for your arms

All moving parts on the Freedom Chair are bike parts, so this rugged wheelchair is easy to customize and easy to service.


We intentionally engineered the GRIT Freedom Chair with as many off-the-shelf bike parts as possible. This allows us as a company to build chairs far quicker than our competitors, but more importantly, it opens a lot of creative and practical windows for our riders.

First, these easy-to-source bike parts make the Freedom Chair easy to maintain. Taking care of your GRIT Freedom Chair is as simple as keeping the tires inflated and occasionally tensioning or greasing the chain.

Second, the Freedom Chair is easy to customize. Our standard bike interfaces allow you to upgrade the chainring, the tires, the wheels, the chains, the freewheels, the handlebar wraps, and more. Need to make an adjustment? Your local bike shop will know just what to do.


Backed by the GRIT Guarantee

An off-road, all-terrain wheelchair is a financial, physical, and psychological commitment. We understand that. We want you to make the right decision for you. Here’s how.


The GRIT team is always thrilled to connect someone with the Freedom Chair, but we know no number of photos, videos, testimonials, or data points can replace the value of using the chair for yourself. And, just as important as using the chair is using the chair on your own turf. Demoing the chair at a convention center is better than nothing, but we want you to take it out on the adventures you had in mind when you first purchased it.

So: Go for it! From the day the chair is delivered, you have 30 days to take it through the snow, the mud, the dirt, the...whatever you’d like. Train in it. Get it muddy. Get it filthy. Challenge yourself in it. Most of all, use your new all-terrain, rugged wheelchair as much and as often as you can.

Almost everyone who uses the chair refuse to give it up, but sometimes it just isn’t a good fit. That’s okay. With the exception of custom parts or models, customers can send their chair back for just the price of shipping (usually $99 both ways). Read more about the GRIT Guarantee below, and fill out the form at the bottom of this page if you have any specific questions!

Knowing there was a 30-day satisfaction guarantee was helpful in getting me over the purchase hump—but once I had the chair, I knew I would love it. Even more important than the guarantee is GRIT’s long-term commitment to rider success. The team has been really proactive in making sure my chair works well for me.
