353 lb of Rated Load on a Frame That Still Weighs 50.6 lbFolding 353 lb Rated 12Ah 12.4 mi

The HKM-5370323 is the highest-rated chair in this frame: 353 lb on a 50.6 lb aluminum build, with a 12Ah pack and 12.4 mi of rated range. At 353 lb this chair carries 88 lb more than the 265 lb versions built on the same platform, and it does it without gaining weight: still 50.6 lb with the pack fitted.

The difference is in how the seat pan and the frame rails take the load, not in extra steel bolted to the outside.

Dual 250W brushless hub motors on a 24V system move that load at walking pace, and the 12Ah pack returns 12.4 mi per charge.

Frame, Motors and Fold

A rating is a working limit, and this one sits well above the rest of the family. The frame is the same aluminum alloy, folded at the same joints, but the seating structure and the rails carry a heavier rider without the sag that starts at the seat pan on a lower-rated chair.

That margin is what a rider near 300 lb is paying for: a chair that is inside its specification every day rather than one running at its ceiling.

It also means the frame absorbs kerbs and uneven ground without the load concentrating on a single joint. The pack detaches for indoor charging, which keeps the chair in the car and the battery on a counter overnight.

Seat 18.9 in wide with a 15.7 in cushion, joystick on either armrest, electromagnetic brake that holds the chair the moment the stick is released. Load rating 353 lb, electrical assembly listed to CE and ISO.

Battery, Range and Charging

Two 250W hub motors drive the rear wheels directly through a 24V controller.

Splitting the drive between two wheels is what lets the chair move a heavier load away from a standstill without the stutter a single motor shows on a ramp or a threshold.

The 12Ah pack returns 12.4 mi per charge with a rider on board. Heavier loads and repeated stops draw more from the pack than a steady run does, so a full charge before a day of errands matters more here than on a lighter build.

Puncture-proof tires mean the chair does not need a pump or a spare tube, which matters when the load on them is higher than on the lighter versions.

Who It Fits and How It Drives

There is no pressure to check before leaving and no flat to change at the roadside. A chair rated to 353 lb still folds like the rest of the family: same latch, same folded shape, same place in a boot.

The rating does not add a second frame to handle or a different procedure to learn before a trip. A rider in the 280 to 353 lb range is the reason this build exists.

• At that weight the chair is working inside its rating rather than at the ceiling
• It also changes how the chair should be loaded
• On a chair this heavy it also pays to check the tire tread for flat spots every few
• A solid wheel does not puncture

What's in the Box

HKM-5370323 ships in one carton with the the product and the parts listed above. Check each item against the list before the first use, and keep the carton for the first month in case something has to go back.

Color and Finish

Check the frame joints and the seat mounting points monthly when the chair carries a rider near its 353 lb rating. That is where wear appears first, and a loose bolt found at home is a repair rather than a breakdown at the far end of a trip.

Charge indoors and unplug at full. Test the brake on level ground before the first trip, keep bags off the push handle so the weight stays inside the wheelbase, and cross slopes square rather than turning on them under load.

Battery Care and Maintenance

The seat measures 18.9 in across with a 15.7 in cushion, and the joystick moves between armrests for either hand.

For a heavier rider, the transfer is the moment that tests a chair, and the pan carries that weight into the rails instead of into the upholstery.

One stick covers forward, reverse, steering and speed; releasing it sets the electromagnetic brake. On an incline that behaviour matters more at this rating, because a chair that has to be held by hand is a chair that can get away on a slope.

The frame folds for a car boot, and the pack comes out first to cut the weight of the lift. At 50.6 lb the chair is heavy enough that two lifts - frame, then pack - are the practical way to load it without straining a shoulder.
