Overview of the APEX Aluminum

The Apex Aluminum Ultralightweight Wheelchair by Motion Composites is designed with your active lifestyle in mind. The Apex frame is made of an AluLite aluminum alloy to provide the lightest weight possible.  Triple butted aluminum tubing reduces weight in non-critical sections and increases strength where needed.  The rigid frame gives the Apex a solid ride and a solid, fully dependable chair.  Unlike most ultra lightweight wheelchairs, you do not have to forfeit adjustability for lightweight.  The Apex chair without wheels in a standard size (16" x 16" seat) weighs just 10.5 pounds.  A fully configured Apex aluminum chair with lightest features weighs just 18 pounds.

What Makes It Different:

The Apex Aluminum features a unique rear rigidizing bar that optimizes the chair’s ride performance.  The Apex’s rigidizing bar increases the rear-frame rigidity allowing for a more open design which increases stability.  This cantilever style frame allows the frame to flex when and where you want it.  The Apex’s frame construction easily absorbs vibrations, giving you a smoother ride than other ultra lightweight wheelchairs. The impact guards at the top of the legrests and the accent pieces on the front bumper and backrest rigidizing bar can be colored in red, blue, orange, white, black, fuchsia, or green.  To give you the truest, most even roll, there are bubble levels on the rear axle and above the caster fork.  The impact guards help to absorb bumps to the chair as well as offer a great grip surface to grab hold of when transferring into and out of the chair.  The front bumper gives protection to the lower portion of the chair and with your choice of the above colors, provides some personalized styling.

Why We Like It:

Wheelchair weights are typically kept low by eliminating adjustability.  The AluLite Aluminum frame changes that restriction.  Whether you are a new user trying to find your ideal set up or an experienced user finding your body has changed over time, the Apex allows you a backrest height, backrest angle, leg length, front and rear seat height, and center of gravity adjustability while still maintaining a frame weight just barely over 10 pounds (16" x 16" seat).  The fully adjustability and detailed configurable design allows the Apex to meet the needs and body comfort of each rider.  The look and cantilever design of the Apex is another bonus.  The minimal cantilever frame allows for a minimal presence so you, the rider are foremost.  People will see you and not the chair first.  When people do see the chair, they will see a very sleek frame promoting a minimalist appearance which emphasizes its fast, sporty performance.  The colored accent pieces allows you to inject your personality into the chair.

Adding to the overall luxury feel of the Apex is the array of Motion Composites’ Newton Accessories, which include Newton One spoke wheels and Newton Gravity ultralight wheels.

Measuring Guide

View Detailed Measurement Guide

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 wheelchair back. Depends on how much upper back support is needed, and also affects freedom for the upper body to rotate.

Rear Seat to Floor³

Measurement from the ground to the rear seat edge. Relative to the front seat-to-floor dimension, this determines the rearward slope ("dump" or "squeeze") of the wheelchair seat.

Hanger Angle⁴

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

Seat Width⁵

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.

Wheel Camber⁶

Angle of the wheel relative to the vertical. More camber improves stability and agility, but also limits ability to pass through narrow spaces. A typical daily wheelchair uses three degrees of camber.

Front Seat to Floor⁷

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. Do not add the footrest clearance if the wheelchair will be foot-propelled.

Footrest Width⁸

Measure from the inside of each legrest tubing the distance or desired distance between legrests.

Center of Gravity⁹

Measure from the front of the seat back post to the center of the rear axel.

Seat to Footrest Length¹⁰

Measure from the edge of the seat upholstery to the top rear of the footrest.

Backrest Angle¹¹

Measure the the angle of the back post to the floor. Ninety degrees will be perpendicular to the floor, to approximate the angle from the back post to the seat, subtract two degrees from measurment for every .5" of dump.
