XSTO M4 Smart Self-Balancing Power Wheelchair

The XSTO M4 Smart Self-Balancing Power Wheelchair is built for riders who want adjustable seating, intelligent balance support, compact indoor control, foldable storage, and app-enabled operation in one advanced power chair.

The M4 uses an automatic self-balancing system to help keep the seat level when riding uphill, downhill, and across daily terrain. The seat height adjusts from 13.66 in to 25.59 in, helping the rider reach tables, counters, desks, and transfer positions more easily.

The M4 also features mecanum front wheels for 360° movement, one-touch folding, modular disassembly, smartphone app control, and a lithium battery system designed for everyday short-distance travel.

Intelligent Self-Balancing Support

The XSTO M4 uses an automatic self-balancing system that adjusts the seat position when going up or down slopes and when crossing certain obstacles. This helps reduce sudden seat angle changes and supports a steadier ride on daily terrain.

Adjustable Seat Height and Tilt

The XSTO M4 adjustable power chair lets the rider change seat height and seat tilt for positioning, transfers, reach, and seated comfort. The height range adjusts from 13.66 in to 25.59 in.

360° Steering With App Control

Mecanum front wheels help the M4 move in tight areas, turn in place, and reposition with less back-and-forth movement. The rider can operate the chair with the joystick, while app control supports remote operation from a smartphone.
