Bangeran Mammoth EX Foldable Heavy Duty Power Wheelchair

This collection is made for people who need a bariatric electric wheelchair with high weight capacity and joystick control. If you weigh 350 lbs, 400 lbs, 500 lbs or more than 600 lbs, you need an electric bariatric wheelchair that is built with reinforced structure and strong drive systems.
Standard power chairs are often limited to 300 or 350 lbs. A true heavy duty electric wheelchair must be designed differently. The frame must be stronger. The base must be wider. The motors must deliver higher torque. The seating system must support wider body types comfortably. A proper bariatric power wheelchair is engineered for strength, not just basic mobility.
Heavy Duty Mobility selected these heavy duty electric wheelchairs based on durability, weight capacity, and long-term performance. These are true bariatric motorized wheelchair models built for daily use.
If you are searching for a 500 lb capacity electric wheelchair, a bariatric power wheelchair 500 lb capacity, a bariatric power wheelchair 600 lb capacity or the 660 lb Porto Ranger Magnum, this page lists every chair by its exact rating.

Two chairs carry a rating of 600 lb or more. The Porto Ranger Magnum is rated 660 lb, folds, and is the highest capacity power wheelchair we sell. The Merits Atlantis is rated 600 lb with a full size captain seat. We do not sell a chair rated above 660 lb, and we would rather say so than stretch a rating. Shopping by build quality rather than rating? See our heavy duty electric wheelchairs.
A bariatric electric wheelchair, sometimes called an electric bariatric wheelchair or bariatric power chair is designed for users who require joystick control and high weight capacity.
Unlike mobility scooters that use a tiller steering column, a bariatric motorized wheelchair is controlled with a joystick. This allows tighter turning radius and easier maneuvering indoors. Many customers searching for the best bariatric electric wheelchair prefer joystick control for indoor use.
For heavier users, the power base must be reinforced and stable. A high weight capacity electric wheelchair for 500 lb person or electric wheelchair for 400 lb person must use thicker frame tubing, stronger welds, and reinforced motor mounts to prevent structural stress.
Bariatric electric wheelchairs typically start at 400 lb and run up to 660 lb.
A bariatric power wheelchair 400 lb capacity model is designed for riders in the mid 300 lb range. A bariatric power wheelchair – 500 lb capacity unit is ideal for riders between 400 and 475 lbs. A bariatric wheelchair 600 lb capacity model supports riders closer to or above 500 lbs.
If you need a bariatric power wheelchair 700 lb capacity, we do not sell one. The Porto Ranger Magnum at 660 lb is the highest rating we carry, and it folds.
If you weigh near 500 lbs, choosing a bariatric electric wheelchair 500 lbs capacity or higher gives better long-term performance. Running a chair at its maximum rating daily can reduce battery life and motor lifespan. Always allow safety margin.
Heavy duty electric wheelchairs use rear wheel drive systems with strong torque output. Larger drive wheels and higher amp controllers allow the chair to move smoothly under heavier loads.
The motor system must deliver steady power without overheating. This is especially important for outdoor ramps or long distance driving.
A bariatric power wheelchair usually has a wider base than standard chairs. This improves balance and reduces tipping risk.
Pneumatic drive wheels help distribute weight evenly. Anti-tip wheels add extra protection. Stability is critical for confidence and daily use.
Many people searching for a bariatric electric wheelchair extra wide seat are also concerned about base width. A wider base supports the wider seating system and improves safety.
A proper bariatric power chair must provide wider seat options, often between 22 and 26 inches. These wider seats are important for comfort and weight distribution.
High back captain seating, reinforced armrests, adjustable seat heights, and deep seat pans are common features in an electric bariatric wheelchair. A strong seating system reduces pressure and improves long-term usability.
A true bariatric wheelchair must feel stable and supportive, not narrow or cramped.
Some customers ask about a folding bariatric electric wheelchair. Folding has caught up with capacity. The Porto Ranger line folds at 400 to 660 lb, the Bangeran Mammoth EX and Porto The Beast fold at 500 lb, and the Magnum folds at 660 lb. The full size Merits Atlantis still wins on seat comfort for all day use.
Higher weight capacity requires heavier frame components. That is why true heavy duty electric wheelchairs are usually not lightweight or ultra-portable.


The Merits Atlantis is one of the strongest bariatric electric wheelchair models available, supporting up to 600 lbs. It is a true bariatric power wheelchair 600 lb capacity design built with a reinforced steel frame and 32 inch wide base for stability.
This bariatric motorized wheelchair features rear wheel drive, pneumatic tires, and up to 32 miles of travel range. Seat widths up to 26 inches make it suitable for users needing an electric bariatric wheelchair extra wide seat configuration.
With a 5 year structural warranty, the Atlantis is a reliable bariatric wheelchair for sale option for customers who need long-term durability and strength. For those asking what is the best bariatric electric wheelchair, the Atlantis is one of the strongest options in the 600 lb category.
A bariatric electric wheelchair must feel stable, responsive, and solid under higher weight loads. The motors should not struggle. The base should not feel narrow. The seating should provide full support.
This collection focuses only on high weight capacity bariatric power wheelchair models built for real strength and long-term reliability. Whether you need a 500 lb capacity electric wheelchair, a bariatric wheelchair 500 lbs, or a bariatric wheelchair 600 lb capacity, Heavy Duty Mobility can guide you with confidence.
If you are unsure which electric wheelchair for 500 lb person or 400 lb user is best, contact us and we will help you choose the safest and strongest option.
If the transfer itself needs help rather than the chair, look at our electric patient lifts.
Take your real weight and add 50 to 75 lb of headroom, then pick the rating above that. A chair run at its ceiling every day heats its motors, shortens its range and wears its suspension. A 300 lb rider belongs in a 400 lb chair, a 400 lb rider in a 450 or 500 lb chair, and a 500 lb rider in a 600 lb or higher chair.
For a rider up to about 330 lb, yes, and the 400 and 440 lb Porto chairs all fold for the car. Above that, step up to the 450 and 500 lb tiers.
The Porto Ranger Magnum at 660 lb, a folding chair with a 22, 24 or 26 in seat. The Merits Atlantis is next at 600 lb.
Yes. The Porto Ranger The Beast and all four Bangeran Mammoth EX builds fold and are rated 500 lb, and the Porto Ranger Magnum folds at 660 lb.
The Porto Ranger Magnum comes with a 22, 24 or 26 in seat, the Merits Atlantis has a 24.5 in seat, and the Avid by Merits Ultra HD can be built from 18 to 24 in. Call 1-888-233-5563 with your hip width and we will match the seat first and the rating second.
