Extreme Motus All-Terrain Wheelchair: Sizing & Custom Options (2026)

It’s nearly impossible to make one piece of adaptive equipment that works for every body and every disability. So the Motus is designed to be modified — sized to the rider, padded for trunk control, fitted with the right headrest, and (when our customers ask) painted whatever color they want. This page covers the standard customization options and what we charge for them.

What size all-terrain wheelchair is right for me?

The Extreme Motus comes in three sizes. The only difference between them is seat width:

• Large — 18″ wide
• Medium — 16″ wide
• Small — 14″ wide

Sam, who stars in all of our videos, uses a medium. He’s about 5’1″ and 85 lbs — comparing your size or your rider’s size to Sam is a useful starting point.

If your rider is a kid who’s still growing, size up. You can always pad a larger seat with blankets, towels, pool noodles, or hardware-store foam. You can’t make a small chair bigger.

For riders with limited trunk control, the aluminum side “wings” of the seat can be bent in or out for more or less lateral support. This is a quick adjustment we can do before shipping or you can do at home.

Seatbelt or 5-point harness?

The seat reclines about 30 degrees and the chair wraps around the rider on the sides, so plenty of users do fine with the standard seatbelt. That said, almost every chair we ship goes out with a 5-point harness — the extra security is worth it, especially for kids and on rougher terrain. Add it during checkout.

Custom headrests

We’ve installed a wide range of headrests for customers — from simple foam pads to full quad-style headrests with lateral supports. The process:

1. You tell us the headrest you want (a brand and model, or send a photo).
2. Our shop confirms whether it’s doable on the Motus frame.
3. You send measurements (rider height, seated height to the back of the head) so we install at the right point.
4. We drill the aluminum frame and mount the headrest before shipping.

Pricing varies by headrest model — we’ll quote you once we know what you want.

Extreme Motus for tall riders (extra-long footrest)

If your rider is over 6 feet tall, or has a disability that limits knee bend, choose the extra-long footrest option (+$200) at checkout. This adds 5 inches to the footrest assembly so the legs sit comfortably without cramping or forced flexion.

Custom embroidery

We can embroider your logo, name, organization, or other artwork on the seat headrest. $200 add-on, plus a few extra days of build time. Send us your artwork (vector files preferred) and we’ll work with our embroidery vendor to put it on before shipping.

Custom colors (powder coat)

Standard Motus frames come in blue or red, kept in stock. Want something different? Our powder coater can do almost any color. $400 add-on, plus up to 4 weeks of additional build time while the frame goes to the powder coater and back. We’ve done greens, oranges, blacks, custom team colors, two-tones, and more.

What we can’t do (and who can)

Some customer requests are outside what our shop is set up for — extensive tilt-in-space mods, specialized switch controls, integrated power assists, etc. When that happens, we refer customers to a local Assistive Technology Program (ATP).

In Utah, that’s Dan O’Crowley at the Utah Assistive Technology Program (UATP) at Utah State University. UATP is part of the Institute for Disability Research, Policy & Practice (IDRPP) and specializes in repurposing and customizing assistive technology — they refurbish donated equipment, run a statewide device exchange (AT4All), and provide custom modifications at modest service fees. Their Salt Lake City facility specifically focuses on mobility devices.

Most U.S. states have similar programs — usually housed at a state university or independent living center. Your state’s AT Act program is the easiest place to start (search “[your state] assistive technology program”).

FAQ: Customizing your Extreme Motus

How much does a customized Extreme Motus cost?

The base price is $4,500. Common add-ons: 5-point harness (varies, often included), extra-long footrest +$200, custom headrest (varies by model), custom embroidery +$200, custom powder coat color +$400. Most customized chairs land between $4,700 and $5,500. Shipping is around $375. Full pricing in our online store.

How long does a custom Motus take to build and ship?

Standard configurations typically ship in 1–3 weeks depending on stock. Custom embroidery adds a few days. Custom powder coat colors add up to 4 weeks because the frame ships to the powder coater and back. We’ll give you a firm timeline at order.

Can the Extreme Motus accommodate quadriplegic riders?

Yes — many of our customers are quadriplegic. The standard recline plus a 5-point harness handles a lot. We can also install custom headrests with lateral supports, deeper trunk wings, and other supports as needed. Talk to us about your specific situation before ordering.

Can I add a power-assist motor to the Extreme Motus?

That’s outside what our shop is set up for. The Motus is purpose-built as a manual chair — adding a power assist would require structural and frame modifications we’re not able to do well. If a powered chair is what you need, the 2026 Price Guide covers Action Trackchair, TerrainHopper, Magic Mobility, and other powered options.

What if I need a modification that’s not on this page?

Just ask. We’ve done one-off mods that aren’t documented anywhere — sometimes we can do them, sometimes we’ll refer you to an Assistive Technology Program in your state. Email me with what you’re trying to accomplish and we’ll figure it out.

Ready to spec your chair?

You can configure most options directly on the product page. For anything custom — headrests, unusual sizing, paint colors not in the dropdown — just send me an email and we’ll work it out.
