Overview

Rear view of the Mammoth Ergonomic showing dual motors and 12 inch tires

The Bangeran Mammoth Ergonomic All Terrain pairs 12 inch pneumatic rear tires and dual suspension with a 3 second remote controlled fold. Its airline friendly 12Ah lithium battery carries riders up to 300 lb for up to 12 miles.

The Bangeran Mammoth Ergonomic All Terrain is the comfort focused member of the Mammoth family. Where the standard Mammoth uses a fixed 18 inch backrest, this version adds a taller 16 inch wide backrest that adjusts from 18 to 24 inches, a 20 inch wide seat with a thick foam cushion and a higher 20 inch seat height that makes standing transfers easier for taller riders.

All terrain ability comes from 12 inch pneumatic rear tires, 8 inch solid front tires and dual shock absorbing suspension. That combination lets the chair roll over grass, gravel paths, cobblestones and speed bumps that stop smaller travel chairs, while intelligent electromagnetic brakes hold it steady on slopes.

The party trick is the fold. Press a button on the included Bluetooth remote from up to 10 yards away and the aircraft grade aluminum frame collapses in about 3 seconds to a 24 by 17 by 30 inch package that fits a car trunk or closet. At 64 lb with the battery installed it stays manageable for a caregiver, and the 12Ah lithium battery is airline friendly for cruise and flight travel.

With a 24V 500W dual motor drive, a 4 mph top speed, up to 12 miles of range and a 300 lb weight capacity, the Mammoth Ergonomic All Terrain suits full size adults who want one chair for the house, the park and the airport.

How is the Mammoth Ergonomic All Terrain different from the standard Bangeran Mammoth?

The Ergonomic has a wider 20 in seat with a thick foam cushion, a higher 20 in seat height and a 16 in wide backrest that adjusts from 18 to 24 in. The standard Mammoth uses a 19.5 in seat with a fixed lower backrest. The Ergonomic suits larger and taller riders who want more support, and the higher seat makes standing transfers easier.

Can the Mammoth Ergonomic All Terrain handle grass and gravel?

Yes. The 12 in pneumatic rear tires, 8 in solid front tires and dual shock absorbers are made for grass, gravel paths, cobblestones and speed bumps. Keep to gentle slopes of about 6 degrees or less. The intelligent electromagnetic brakes hold the chair steady on a slope.

How does the Mammoth Ergonomic remote folding work?

A Bluetooth remote is included and works from up to 10 yards away. Press the fold button and the aluminum frame collapses in about 3 seconds to 24 x 17 x 30 in, small enough for a car trunk or a closet. The same remote unfolds the chair and can drive it short distances without a rider.

How much does the Mammoth Ergonomic weigh, and can one person lift it into a car?

It weighs about 64 lb with the battery installed. A built in handle under the seat helps with lifting. Many caregivers manage it alone, but taking the battery out first or lifting with two people makes it easier. Check the folded size of 24 x 17 x 30 in against your trunk opening.

What is the weight capacity of the Mammoth Ergonomic All Terrain?

It carries riders up to 300 lb, about 136 kg. The seat is 20 in wide and 18 in deep, and the armrests sit 29 in high. Riders over 300 lb should look at a bariatric model with a higher rating.

How far does the Mammoth Ergonomic go on a charge?

Up to 12 miles on its 12Ah lithium battery. Grass, gravel, slopes and rider weight shorten that, so treat 12 miles as the rated maximum. A full charge takes 6 to 8 hours, and the 500W dual motor drive gives a 4 mph top speed.

Can I take the Mammoth Ergonomic battery on a plane?

The 12Ah lithium battery is listed as airline friendly and is designed to meet airline guidelines for mobility devices. Each airline applies its own approval process for battery powered wheelchairs, so have the battery specifications ready and confirm with your airline before you fly.

Will Medicare or insurance pay for the Mammoth Ergonomic?

Medicare will not pay for it when bought here. Heavy Duty Mobility does not hold a Medicare supplier number and does not bill Medicare, Medicaid or private insurance. Some private plans reimburse you directly, so ask your insurer. If they agree, we provide an invoice and proof of purchase for your claim.

How is my chair delivered?

Delivery to your curb is free. Check the packaging and the chair before you sign for it, and call 1-888-233-5563 if anything looks wrong.

Can I pay over time?

Yes. Choose Klarna at checkout to pay over time. See how financing works.

Can I talk to someone before I buy?

Yes. Call 1-888-233-5563. Real people answer, business hours and weekends.
