A 330 lb Rating With Puncture Proof Tires for Gravel and DirtFolding 24Ah 330 lb 12.4 Mile 50.6

The HKM-3338707 combines the 24Ah pack with a 330 lb rating in an all-black build, and its puncture-proof tires are chosen for ground that is not always paved. This is the heavier-rated version of the 24Ah folding chair: 330 lb load capacity, 50.6 lb with the pack fitted, dual 250W brushless hub motors on a 24V system.

The extra capacity is in the structure rather than in added weight, so it still folds into the space of the lighter builds.

Range is rated at 12.4 mi per charge on the 24Ah pack, and the pack detaches so charging can happen indoors while the chair stays folded in the car.

Frame, Motors and Fold

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

Hub drive has no exposed chain or belt, which matters on gravel: there is nothing at ankle height to catch grit, and nothing to lubricate after a wet week outdoors.

The 24Ah pack is the capacity option for this frame and is rated at 12.4 mi per charge. It lifts out without tools, so the chair can stay in the car while the pack charges indoors, and a second pack can travel in a bag for a full day away from an outlet.

Tread meant for gravel and packed earth makes this the build for a driveway that turns to dirt at the end of the pavement. Seat 18.9 in wide, 15.7 in cushion, joystick on either armrest, electromagnetic brake that holds the chair when the stick is released.

Battery, Range and Charging

Tires are puncture-proof and built for surfaces beyond a hallway: gravel, packed earth, and a lawn that has gone soft after rain.

Solid rubber means no tube to pinch and no pressure to check, at the cost of a firmer ride than an air-filled tire on old concrete.

The 330 lb rating sets this build apart from the 265 lb versions that share its motor and pack.

For a heavier rider that margin is the reason to choose this chair, and it is also what keeps the frame stable when a bag is added to the seat back on a slope.

Who It Fits and How It Drives

The aluminum frame folds for a car boot and the pack comes out first, so the lift into the vehicle is lighter than the 50.6 lb total suggests.

Folded, it takes floor space closer to a large suitcase, which leaves the rest of the boot for shopping. Keeping the chair in a car is realistic at this weight because the frame and pack split into two lifts.

• Charge the pack indoors overnight
• A driveway that ends in gravel is where the tread on this build does its work
• The tire bites into loose stone instead of skating over it
• Grass after rain is the harder case: the tires cut through the surface layer rather

What's in the Box

Color and Finish

After use on gravel or dirt, clear grit from the hubs, the caster forks and the folding latch before the chair is folded away. Grit left in a joint works like sandpaper on the pivot and is the usual reason a frame starts to stiffen over a season.

Charge indoors and unplug at full. Test the brake on level ground, keep the joystick free of dust, and treat wet grass and loose gravel as surfaces to cross slowly rather than to turn on with weight on one side.

Battery Care and Maintenance

A brush is more useful than a hose on this chair. Knock the dirt off the tires and the frame before folding, and wipe the hubs with a dry cloth, since water pushed into a hub seal does more harm than the dust it was meant to remove.

An 18.9 in seat over a 15.7 in cushion holds an adult rider square, and the joystick can be swapped between armrests for a left-handed rider or a caregiver who walks on one side of the chair by habit.

The stick covers forward, reverse and steering, and releasing it engages the electromagnetic brake. On uneven ground that behaviour is what keeps the chair from rolling when the rider stops to talk, open a gate, or wait at a crossing with the chair on a slight camber.

For a rider who drives with one hand, the stick sits at armrest height and needs no grip strength beyond a thumb and forefinger. That is also why the brake is automatic: on a chair rated to 330 lb, a parking lever that has to be pulled by hand is one more thing that gets skipped on a slope.
