A power assist wheelchair is a mobility device that combines manual or rollator-style movement with an integrated electric motor, adding powered propulsion to reduce the physical effort required from the user or caregiver.
Unlike a fully electric power chair — where the motor does all the work — a power assist wheelchair supplements human effort rather than replacing it. The motor senses pushing force or walking pace and adds proportional drive, so inclines, long distances, and uneven terrain require significantly less exertion. On SINCEBORN's multi-mode devices, this system operates through C1–C3 motor settings that automatically read movement speed and adjust output in real time, whether the user is walking with the device or being pushed by a caregiver.
- Power assist wheelchairs use onboard motors to supplement — not replace — manual pushing effort from a user or caregiver.
- SINCEBORN's power assist system offers three motor output levels (C1, C2, C3), with a maximum assisted speed of 6 km/h (approximately 3.7 mph).
- In caregiver transport mode, the motor reduces push effort for the person at the rear handles — not for the seated user.
- SINCEBORN's 4-in-1 model uses a 600W magnesium alloy motor (two 300W rear motors) supporting a 254 lb weight capacity across all modes.
- Power assist mode is distinct from self-drive mode: self-drive requires the user to operate a 360-degree front joystick independently.
