Kerdom DX08 Review: The 25.8 lb Carbon Fiber Wheelchair Worth the Hype?

There is a number on the Kerdom DX08 spec sheet that stops you on the first read: 25.8 pounds. That is the weight of the chair without its battery, and it is lighter than a lot of folding manual wheelchairs that have no motor at all. For anyone who has wrestled a 50-pound power chair into a car trunk, or skipped a trip because the logistics of moving a wheelchair felt heavier than the chair itself, that single figure is the whole pitch.

But weight is only worth something if the rest of the chair holds up. A featherweight frame that runs out of range in two miles, or can’t climb a curb cut, or feels twitchy under a real adult body, is not a bargain at any price. So this Kerdom DX08 review looks past the headline number at the parts that decide whether a power chair is genuinely usable: range, ride, build quality, and the actual experience of traveling with it.

If you have already read our Kerdom DX07 review, think of the DX08 as the answer to the one complaint that chair couldn’t fully solve - weight. Here is how it earns the upgrade, and where it asks you to compromise.

What Makes the DX08 Different

Kerdom builds a full ladder of folding power wheelchairs, and the DX08 sits at the top of the ultra-light line. Where the DX07 leans on a carbon-and-aluminum frame to reach 41.5 lbs, the DX08 goes further: a near-full carbon fiber structure that drops the frame weight to 25.8 lbs, or 29.8 lbs with the battery clipped in.

Two things separate it from everything below it in the catalog. The first is that carbon frame, which is not a marketing flourish here - it is the only way to hit this weight while still carrying a 300-pound rider. The second is the Bluetooth remote control. The DX08 can be driven empty, from outside the chair, which sounds like a gimmick until you are a caregiver trying to reposition a chair in a tight hallway or roll it up to a car door without lifting it. It is a genuinely practical addition that most chairs in this class do not offer.

The price reflects the position: $1,769.99, listed down from $3,965.99. That is $400 more than the DX07, and the question this review keeps returning to is whether the 15-pound weight saving and the remote justify that gap.

Kerdom DX08: Full Specifications

Here is the complete spec sheet before we get into how it actually rides:

Specification	Kerdom DX08
Weight (without battery)	25.8 lbs
Weight (with battery)	29.8 lbs
Battery	24V 10Ah / 240Wh lithium-ion (removable)
Range	13.5–20.5 miles per charge
Max Speed	3.73 mph
Weight Capacity	300 lbs
Motors	150W × 2 brushless (300W total)
Seat Width	18.85 inches
Folded Dimensions	24.8″L × 10.2″W × 28″H
Turning Radius	22 inches
Max Incline	12°–18.9°
Tires	8″ front / 11″×8″ solid rear
Charging Time	4–8 hours
Battery Lifespan	~2,000 charge cycles (3–5 years)
Control	Joystick + Bluetooth remote
Frame	Carbon fiber
Warranty	5 years

Two numbers deserve a second look. The 10.2-inch folded width is the standout - that is slim enough to slide behind a car seat or into a closet gap, not just a trunk. And the 240Wh battery is larger than the DX07’s 180Wh pack, which matters for both range and air travel. More on the travel side below, because it is the detail most reviews get wrong.

Design, Frame, and Build Quality

Pick the DX08 up and the carbon fiber is immediately obvious. The frame has the slightly hollow, resonant feel of carbon rather than the dead heft of steel, and the weave is visible on the structural tubes - this is real carbon, not a printed wrap over aluminum. At 25.8 lbs, most adults can lift it one-handed, which is the entire point.

The seat is a sling-style padded surface at 18.85 inches wide, which lands in the average-to-roomy range and fits most riders comfortably without feeling cavernous. Armrests flip up for side transfers, and the backrest folds forward, which is part of how the chair collapses so flat. Build tolerances feel tight - no rattle in the joints, no flex in the seat frame under load.

The tradeoff for carbon’s stiffness is ride feel. The 8-inch front casters and 11-inch solid rear tires are puncture-proof, which means you will never be stranded by a flat, but they also transmit more of the ground into the seat than an air tire would. On smooth indoor floors and good pavement this is a non-issue. On broken sidewalk or cobblestone, you feel it. This is the honest cost of a chair built to be light and maintenance-free.

Portability: Folding and Travel

This is where the DX08 stops being just a lighter DX07 and becomes a different proposition.

The fold is a single motion - release the latch, and the carbon frame collapses vertically into a block 24.8 inches long, 10.2 inches wide, and 28 inches tall. That width is the headline. A DX07 at 14 inches fits a trunk; the DX08 at 10.2 inches fits places a trunk-sized chair can’t - behind the front seats of a sedan, into an overhead bin, down the side of a closet. Combined with the sub-26-pound frame, this is the first Kerdom chair that one average-strength person can fold, lift, and stow without a routine that strains their back.

The Bluetooth remote earns its keep here too. Instead of lifting the folded chair across a parking lot, you can unfold it, drive it empty to the car door, then lift only at the final step. For caregivers, that changes the daily math entirely.

Air Travel: The 240Wh Question

Most reviews either call the DX08 “airline approved” with no explanation or wrongly flag its 240Wh battery as a dealbreaker. Both are sloppy. Here is the accurate version.

Standard carry-on lithium battery rules cap loose batteries at 100Wh freely, and 101–160Wh with airline approval. By that rule alone, a 240Wh pack looks blocked. But power wheelchair batteries are not governed by the standard carry-on rule. Under the US Department of Transportation’s Air Carrier Access Act, batteries that power a mobility device are treated as mobility-aid batteries, and airlines are required to accept them - including a single spare or removed battery up to 300Wh. The DX08’s 240Wh pack falls under that ceiling.

In practice, that means:

1. Notify the airline at booking - power chairs require advance notice, usually 48 hours.
2. Remove the battery before the frame is gate-checked or stowed; the battery travels in the cabin as a mobility-aid battery.
3. Carry the spec sheet showing 240Wh so gate agents can verify it against the 300Wh mobility-aid limit, not the 160Wh carry-on limit they may default to.
4. Confirm with international carriers separately, since rules outside the US can be stricter.

We cover the full process in our guide on traveling by plane with an electric wheelchair. The short version: the DX08 is travel-legal, but “airline approved” still requires you to do the paperwork.

Real-World Performance

On the road, the DX08 drives like a chair that knows it is light. The dual 150W brushless motors deliver a top speed of 3.73 mph - a confident walking pace - and the independent rear-wheel drive gives it a tight 22-inch turning radius that clears standard doorways and tight retail aisles without three-point turns.

The rated range is 13.5 to 20.5 miles. As always, treat the top figure as a lab number: on flat pavement at an average rider weight, plan for the lower-to-middle of that band, roughly 11–15 miles of real use, with hills and heavier loads pulling it down. For a chair used around a home, a neighborhood, a campus, or a cruise ship, that is comfortably a full day of mobility. The 240Wh battery is a meaningful step up from the DX07 here, and it recharges in 4–8 hours.

The 300-pound weight capacity is the one place the DX08 asks you to check the fit. It is lower than the DX07’s 350-pound rating - the price of the lighter frame. Riders near or above 300 pounds should size up to the DX07 or the heavier-duty DX05 instead.

Who the Kerdom DX08 Is For

The DX08 is the right chair if portability is the single thing that decides whether you actually use a power chair. Frequent flyers, cruisers, caregivers who load a chair into a car several times a day, and anyone living somewhere with limited storage will feel the 25.8-pound frame and 10.2-inch fold every single day - and that daily relief is worth the premium.

If you weigh near 300 pounds, mostly stay on rough outdoor terrain, or simply don’t need the lightest possible chair, the Kerdom DX07 delivers similar real-world performance with a higher weight rating for $400 less, and the budget-focused DX04 covers the essentials for under $800. We line all three up directly in our Kerdom wheelchair comparison, and our complete buying guide walks through how to match a model to how you actually live.

Final Verdict: Is the Kerdom DX08 Worth It?

At $1,769.99, the Kerdom DX08 is not the cheapest way into a folding power chair - it is the most portable. The 25.8-pound carbon frame, the 10.2-inch fold, and the Bluetooth remote combine into something the rest of the lineup can’t match: a power wheelchair that genuinely disappears into your life instead of dictating it. The 240Wh battery backs it with real range, and the 5-year warranty removes the risk from the spend.

It is not for everyone. Heavier riders and rough-terrain users are better served elsewhere in the Kerdom range. But for the traveler, the caregiver, and the small-space dweller, the DX08 answers the one question that keeps people from buying a power chair at all - can I move it myself? - with a confident yes.
