Overview
The HKM-322899 is a heavy-duty folding electric wheelchair designed for riders who need a higher weight capacity than standard power chairs typically offer. The reinforced aluminum-alloy frame is rated for riders up to 440 lb (200 kg), while the chair remains portable at roughly 55 lb (24.9 kg) net weight without the battery and joystick. A one-touch folding mechanism collapses the chair into a slim package that fits in the trunk of a sedan or SUV -- no tools required.
Two quiet 250 W brushless hub motors mounted on the rear wheels provide balanced, responsive propulsion with a combined 500 W of power. The intelligent electromagnetic braking system engages automatically the moment the joystick returns to neutral, holding the chair securely on slopes up to 8 degrees. The 360-degree joystick controller mounts on either armrest and offers intuitive speed control for hallways, elevators, sidewalks, and parking lots.
From navigating a home or office to loading the folded chair into a vehicle for a weekend trip, the HKM-322899 delivers the strength and range heavier riders need -- in a package light enough for a caregiver to lift and compact enough to store in a closet.
Key Features
Intelligent Electromagnetic Brake
The upgraded electromagnetic braking system brings the chair to a controlled stop as soon as the joystick is released. On inclines up to 8 degrees the chair holds firmly in place, adding security during transfers and stops on ramps.
One-Touch Fold with Foldable Footrest
A quick-release mechanism folds the chair into a compact standing package in seconds. The footrest folds flat in about 3 seconds for an even slimmer profile. The folded dimensions fit easily in most car trunks, closets, and storage spaces.
360-Degree Joystick Controller
An ergonomic joystick provides forward, reverse, and steering control along with a speed dial, horn button, and battery-level indicator. The mount can be swapped between the left and right armrest.
Reinforced Aluminum-Alloy Frame
The lightweight yet rugged aluminum-alloy frame is engineered for a 440 lb (200 kg) load rating while keeping net weight at approximately 55 lb (24.9 kg) without the battery. Corrosion-resistant finish for long-term durability.
Solid Covered-Rim Tires
Large solid rear drive wheels with covered rims and smaller solid front casters. No air to inflate, no flats -- reliable grip on pavement, tile, carpet, and hard surfaces with minimal maintenance.
Lift-Up Armrests & Safety Belt
Flip-up armrests make side transfers from beds, sofas, and car seats easier. A padded lap belt holds the rider securely in place over longer rides and uneven ground.

Battery & Range
The HKM-322899 uses one removable 24 V 12 Ah lithium-ion battery pack. Energy stored: 288 Wh (calculated as voltage x ampere-hours: 24 V x 12 Ah = 288 Wh). On a full charge, riders typically cover up to about 12.4 mi (20 km) on flat pavement at moderate speed. Actual range varies with rider weight, terrain, wind, temperature, and stop-and-go patterns.
Tip: Charging the battery while it is off the chair (off-board) is convenient for travelers. The included 100-240 V charger works in most countries with the appropriate plug adapter. A full top-up from empty takes 6-8 hours; topping up after a short ride takes less time.
For airline travel, the 24 V 12 Ah / 288 Wh lithium pack falls within the size range many airlines accept for carry-on mobility devices when carried per their rules. Always confirm with your airline before flying -- rules vary by carrier, route, and battery policy.
Daily Use & Care
- Before riding: Confirm the joystick battery gauge reads a healthy charge level, the battery pack is fully seated and latched in its mount, and the joystick mount is secured on the chosen armrest.
- Transfers: Flip up both armrests and fold the footrest upward to side-transfer from a bed, sofa, toilet, or car seat. The lift-up design gives you extra clearance.
- Folding and unfolding: Switch the chair off, press the red collapsible button on the rear frame, and fold the footrest up -- the chair collapses into a compact standing package in seconds. Pull the frame open and it locks into riding position.
- Tire care: Solid covered-rim tires do not require inflation. Wipe them with a damp cloth to remove grit and check the tire surfaces monthly for cracks or wear.
- Battery care: Avoid storing the battery fully discharged for long periods. Top up at least once a month during storage, and charge indoors at room temperature using only the included charger.
- Cleaning: Wipe the aluminum frame with a soft, damp cloth and mild neutral detergent. Do not soak the joystick, battery compartment, or motor hubs. Dry thoroughly after cleaning.
- Weight awareness: This model is rated for riders up to 440 lb (200 kg). Staying within the rated capacity preserves frame integrity, motor life, and brake performance.

Frequently Asked Questions
Is the HKM-322899 airline-friendly?+
The 24 V 12 Ah lithium battery stores 288 Wh and falls within the size range many airlines accept for mobility devices when carried per their rules. Some carriers require advance notice or that batteries be carried in the cabin. Always confirm with your airline before flying.
How far will it go on a single charge?+
Riders typically cover up to about 12.4 mi (20 km) per full charge on flat pavement at moderate speed. Range decreases with heavier riders (closer to the 440 lb limit), hills, headwinds, cold weather, and frequent starts and stops.
Can the joystick be moved to the other armrest?+
Yes. The 360-degree joystick mount is designed to swap between the left and right armrest so the chair can be set up for left- or right-handed riders.
What makes this a heavy-duty wheelchair?+
The reinforced aluminum-alloy frame is engineered and tested to support riders up to 440 lb (200 kg) -- well above the 265-330 lb capacity of many standard lightweight power chairs. The dual 250 W motors and electromagnetic brake are sized accordingly for confident performance under heavier loads.
Is it safe on small hills and ramps?+
The HKM-322899 is rated for slopes up to about 8 degrees. The intelligent electromagnetic brake holds the chair in place whenever the joystick returns to neutral, preventing rollback on inclines.
Do the tires need air?+
No. Both the front casters and the rear drive wheels use solid tires with covered rims, so there is nothing to inflate and no risk of pinch flats. Keep the tire surfaces clean and free of debris.
What is the rider weight limit?+
The reinforced aluminum-alloy frame is rated for riders up to 440 lb (200 kg). For safety and longevity, do not exceed this limit.
How long does it take to charge?+
A full charge from empty takes about 6-8 hours with the included 24 V 2 A charger. Topping up after a short ride takes proportionally less time.
Can it be used as a manual wheelchair?+
Yes. Release the motor locks on the rear hubs (per user manual) so a caregiver can push the chair like a manual wheelchair when needed. Re-engage the locks for powered drive.
How do I fold and unfold it?+
To fold: ensure the chair is off, press the red collapsible button on the rear frame, fold the footrest up, and collapse the frame -- it forms a slim standing package in seconds. To unfold: pull the frame open until it locks into position, lower the footrest, and you are ready to ride.
How much does the chair weigh?+
Net weight is approximately 55 lb (24.9 kg) without the battery and joystick installed. With the battery attached, total weight is around 62 lb (28 kg). One caregiver can typically lift the folded chair into a vehicle.

Why Choose the HKM-322899
440 lb (200 kg) Heavy-Duty Capacity
The reinforced aluminum-alloy frame supports riders up to 440 lb (200 kg) -- built for those who need more capacity than many 265-330 lb power chairs offer, without the bulk of a traditional heavy-duty chair.
Holds Securely on 8 Degree Slopes
The intelligent electromagnetic brake engages instantly when the joystick is released. No roll-back on ramps, no creeping on inclines -- secure stops every time.
Travel-Ready Folding Design
One-touch folding collapses the chair to roughly 26.8 x 23.2 x 16.7 in (680 x 590 x 425 mm). Light enough for one caregiver to lift into a sedan trunk; small enough for closets and storage rooms.
Removable 288 Wh Lithium Battery
Snap the 24 V 12 Ah battery out for off-board charging or to lighten the chair for lifting. At 288 Wh (24 x 12), the pack provides solid everyday range and falls within common airline mobility-device guidelines.

Pre-Ride Safety Checklist
- Battery check. Confirm the battery pack is fully seated, the anti-theft latch is locked, the gauge shows a healthy charge level, and connections are secure.
- Brake check. With the chair powered on a flat surface, release the joystick -- the chair should stop immediately and hold in place via the electromagnetic brake.
- Tire check. Inspect all solid tires (front casters and rear drive wheels) for cracks, embedded debris, or unusual wear on the tread surface.
- Joystick check. Move the joystick through its full range of motion; the chair should respond smoothly in all directions without jitter or delay.
- Footrest check. Confirm the footrest is locked in the deployed position before placing weight on it.
- Armrest check. Ensure both lift-up armrests are latched securely in the down position before riding.
- Motor lock. Confirm motor locks are engaged (drive mode) before powering on for riding.
- Environment scan. Check the path for steps, steep slopes (above 8 degrees), standing water, ice, loose gravel, or obstacles before driving off.
Quick Troubleshooting
The chair will not power on.+
Confirm the battery pack is fully seated in its mount, the charge level is not empty, and the power button is being held long enough to register. Try connecting the charger -- if the charger indicator lights up, the battery is recognized. If the chair still does not power on, contact support.
The motors do not respond to the joystick.+
Check that the motor locks are engaged (drive mode), the electromagnetic brake is not faulting, and the chair is powered on. Power the chair off and back on. If the joystick indicator shows an error code, note it and contact support.
The driving range is shorter than expected.+
Range depends on rider weight (heavier riders closer to the 440 lb limit will see reduced range), terrain, wind, temperature, and stop-and-go patterns. A battery that no longer holds a full charge after many cycles may need replacement.
The chair rolls on a slope when the joystick is centered.+
The electromagnetic brake should hold the chair whenever the joystick is in neutral. If it does not, power off, engage any available mechanical lock, and contact support. Avoid leaving the chair unattended on slopes.
The joystick mount feels loose.+
Power off the chair, check the mount clamp for tightness, and reposition the joystick to your preferred side. If the mount itself is damaged, a replacement mount is available as a spare part.
The chair feels sluggish under heavy load.+
Ensure the battery is fully charged and the tires are clean and free of debris. If sluggishness persists, verify the rider is within the 440 lb (200 kg) weight limit and contact support for a motor inspection.
