Product Description

Mammoth EX Automatic Recline Bariatric Portable Power Wheelchair

The Mammoth EX Automatic Recline Portable Electric Wheelchair is a high-performance bariatric mobility solution built to provide exceptional strength, deep postural comfort, and rugged terrain performance without compromising travel convenience. Engineered around a reinforced aircraft-grade aluminum alloy frame, this heavy-duty power wheelchair easily accommodates user weight capacities up to 400 lbs while keeping the chassis weight to an agile 73 lbs (plus a 7 lb detachable battery). Designed for seamless all-terrain navigation, it incorporates dual rear shock absorbers and responsive wheels to deliver a balanced, vibration-free ride across grass, gravel, hard-packed sand, snow, and uneven outdoor paths.

A primary standout of the Mammoth EX is its motorized automatic reclining backrest, controlled smoothly through a 360-degree waterproof digital joystick or the included wireless remote control. The system transitions effortlessly from an upright driving posture to a relaxed, bed-like angle paired with an adjustable headrest for pressure relief and extended daily rest. Seating comfort is centered around an extra-wide 21.5" seat with 22" of clear width between armrests and a 5-inch thick, high-density foam cushion wrapped in breathable, antiseptic upholstery. Powered by dual 250W motors (500W total output) and a fast-charging 24V 12AH lithium battery, it delivers a driving range of up to 12 miles at speeds up to 4 mph. Fully compliant with TSA and FAA airline and cruise regulations, the Mammoth EX collapses manually to a compact 16.5" profile for effortless trunk loading and worldwide travel.

Usage, Recline & Battery Care Guidance

To operate, power on the 360-degree digital joystick and use the recline toggles to adjust the backrest angle. To fold the frame manually, disconnect the safety latch behind the backrest and pull inward until the chair collapses flat. Charge the 24V 12AH lithium battery using only the supplied 2A smart charger; full recharges take between 8 to 12 hours. Clean the aluminum frame and antiseptic cushion covers with a damp cloth and mild disinfectant wipes, ensuring the electronic joystick connections remain dry during maintenance.
