Technical Specifications

Overall DimensionsIncludes overall length, width (open and folded), and height, which are critical for navigating indoor spaces, doorways, and transportation.
Mass/WeightVaries significantly by type. Standard manual chairs can be over 36 lb (16 kg), while ultra-lightweight models can be under 26 lb (11.8 kg). Power wheelchairs typically weigh much more (e.g., 85 kg or more with batteries).
Weight CapacityStandard models typically support up to 250 lb (113 kg), while bariatric or heavy-duty versions can support 350 lb (158 kg) or more.
FrameCan be rigid (single welded frame, more efficient for propulsion) or folding (usually via a cross-brace design, for easy transport). Materials commonly include steel (heavier, cheaper) or aluminum and titanium (lighter, more durable).
Rear/Drive WheelsLarge (e.g., 24 inches in diameter) with push-rims for self-propulsion in manual chairs. Can have solid rubber tires (durable, high rolling resistance) or pneumatic (air-filled, smoother ride, more maintenance).
CastersSmaller front wheels (e.g., 5 to 8 inches in diameter) that facilitate steering and maneuverability.
BrakesManual chairs typically have push-to-lock parking brakes. Power chairs use electromagnetic braking systems for safety.
Postural SupportIncludes components like armrests (fixed, flip-up, or adjustable height), leg rests (fixed, swing-away, or elevating), and various seating cushions and backrests designed for comfort and skin integrity management.
Motor OutputOften specified in wattage (e.g., 2 x 250W or 300W motors).
BatteryTypically 24V systems with varying amperage-hour (Ah) ratings (e.g., 10 Ah to 62 Ah lithium-ion or VRLA batteries).
Range per ChargeCommonly ranges from 15-20 km (around 10 miles).
Max SpeedGenerally up to 6-10 km/h (around 4-6 mph).
Control InterfaceMost commonly a joystick, but specialized options like sip-and-puff or head switches exist.
