The Extreme Motus all-terrain wheelchair ($4,500) is a caretaker-pushed chair built for stability and safety on steep, rugged trails — ideal for riders with quadriplegia, cerebral palsy, MS, or low core strength who want to hike with family.

The Extreme Motus is an all-terrain chair designed for riders who require a caretaker or family member to push, providing maximum stability and safety on steep or rugged trails.

Best for Quadriplegia or Cerebral Palsy: The Extreme Motus
The Extreme Motus is designed for people who want to explore but may not have the upper body strength to propel themselves. Because it is a “pushed” chair, the design focuses on the rider’s comfort and the caretaker’s control.
- Supportive Racing Seat: The Motus uses a high-back seat with lateral support. This is critical for riders with Cerebral Palsy or high-level Spinal Cord Injuries who need help maintaining a steady, upright posture while moving over bumps.
- Dual Disc Brakes: Safety on a descent is everything. The Motus features independent disc brakes on both rear wheels, allowing the caretaker to safely control the speed down steep hills without the chair running away.
- Low-Pressure Balloon Tires: The large grey Wheeleez tires act as a natural suspension, floating over sand, mud, and snow where thinner tires would sink.
Best for Independent Riders: The GRIT Freedom Chair
If your goal is to get a workout and navigate dirt roads on your own, the GRIT Freedom Chair is a fantastic piece of engineering for those with sufficient strength.
- Lever-Drive Efficiency: Instead of pushing on the rims, you use long levers. This is roughly twice as efficient as a standard wheelchair and keeps your hands clean and away from the mud.
- Mountain Bike Parts: The GRIT uses standard bicycle components, which makes it easy to repair or customize at any local bike shop.
- Independence: This chair is built for the “weekend warrior” who has the core and arm strength to tackle inclines and navigate obstacles without needing a push.
Pros and Cons
Extreme Motus All-Terrain Wheelchair
- Pros: Safest for steep descents (dual disc brakes), floats on sand/snow/water, ultra-comfortable for long hikes, light at 49 lbs, fits in a standard SUV.
- Cons: Requires a caretaker to push; not designed for self-propulsion.
GRIT Freedom Chair
- Pros: Provides total independence, lightweight, lower entry price for the base model, mountain bike parts are easy to service.
- Cons: Can be unstable at high speeds; requires significant upper body strength to operate effectively on steep trails; narrower front wheel struggles in soft sand.
Conclusion: Which Should You Choose?
At Extreme Motus, we often find ourselves recommending the GRIT Freedom Chair to customers who have full use of their upper body and want the challenge of a self-propelled workout.
However, if you are looking for a chair that allows the entire family to go hiking together — especially for children or adults with more involved disabilities like quadriplegia or muscular dystrophy — the Extreme Motus is the right choice. It removes the “work” of the trail and replaces it with a shared family experience.

Frequently Asked Questions
Can one person push the Extreme Motus?
Yes. The Motus is balanced so that a single caretaker can easily push and steer the rider across varied terrain, including grass, gravel, and sand. The long wheelbase and balanced center of gravity make it feel significantly lighter to push than a standard chair.
Does the GRIT Freedom Chair work in soft sand?
The GRIT can handle firm sand, but its narrower front wheel and mountain bike tires may struggle in deep, soft sand compared to the large balloon tires of the Extreme Motus.
Which chair is easier to transport?
Both chairs are designed to be disassembled. The Extreme Motus uses quick-release pins to remove the wheels and frame sections; the GRIT also breaks down into a compact size for most trunks.
How much does the Extreme Motus cost compared to the GRIT?
The Extreme Motus is $4,500 in 2026. The GRIT Freedom Chair ranges from $2,995 (base) to $5,495 (premium configurations).
Are all-terrain wheelchairs covered by Medicare?
Generally, no. Most all-terrain wheelchairs are considered “recreational” and are not covered by traditional insurance or Medicare. However, there are many grants available to help families fund these life-changing tools.
