Manuals, Literature & Videos


The eWheels EW-M31 is a rear wheel drive power wheelchair for both indoor and outdoor use.  The M31 has a 31” turning radius which is very tight for a rear wheel drive model.  The M31 gives you the maneuverability to navigate inside the home whether a large living room or the confines of a bathroom. The center of gravity of a rear wheel drive gives you the power to use the M31 outside and on uneven terrain. Knobby tread on the rear tires with a 2.4” ground clearance allows you to take the M31 into a fairly level grassy lawn and even some gravel.

What Makes This Different

The M31 has a surprising amount of adjustability. The footplate can adjust both horizontally as well as vertically to accommodate for leg length and positioning preferences. The armrests have width adjustability to accommodate various body sizes. The headrest on the Captain’s Seat can be raised or lowered per user height. The Captain’s Seat will swivel 360° and lock at each 90°. This makes transfers and positioning significantly easier.

Why We Like It

Versatility and adjustability are the 2 key features of the M31. The ability to use the M31 both indoors and outdoors provides you with a power wheelchair that is just as maneuverable inside as it is powerful enough to handle inclines and the uneven terrain of your neighborhood. The adjustability of the M31 makes it adaptable and comfortable to a number or users and needs.

Measuring Guide

View Detailed Measurements
Seat Depth1
Measure from the most posterior point of the body to the inside of the knee, minus at least two inches. Some prefer more leg overhang to make room for their hand when lifting their leg.

Back Height2
Measured from the seat base to the top of the chair back. Power wheelchair riders need upper back support, particularly for the moment of initial acceleration.

Hanger Angle3
Determines how far the toes extend away from the body, measured from the horizontal. A tighter angle allows the electric power wheelchair to turn around in less space. Depends in part on ability of the knee to bend towards the perpendicular.

Seat Width4
Determined by the widest point of the body from knee to hip, plus an inch to ensure room to move. Consider bulk of clothing, particularly a heavy winter coat, if relevant.

Front Seat to Floor5
Measure the leg from the back of the knee to the sole of the foot. Then subtract the thickness of the cushion when it is compressed. Next, add a minimum of two inches for footrest clearance. Electric power wheelchairs are almost never foot-propelled by the user - so excluding the additional two inch footrest height for propelling is very rare.
