The Newton Gravity is a double-wall alloy rear wheel for Motion Composites wheelchairs, in 20", 22", 24", 25" and 26". It is sold as the wheel alone, one at a time.
The Newton Gravity is Motion Composites' performance wheel for pneumatic tires, with a double-wall rim, stainless steel spokes and a matte black finish.
Built for real life
What stands out
●
670 g at 24"
Less weight at the rim means less effort to get the wheel turning with each push.
●
Double-wall rim
Motion Composites says the double-wall rim adds stiffness and durability.
●
Stainless spokes
Stainless steel spokes with squared heads and a spoke head locking system.
●
Five sizes
20", 22", 24", 25" and 26", in a matte black finish.
The Hieline Take
Weight in a rear wheel costs more than weight anywhere else on a chair, because you spin it up with every push. The Gravity is where Motion Composites took that weight out: 670 g for the 24" wheel. The rim is double-wall, which Motion Composites says adds stiffness so more of each push turns into forward motion, and it is laced with stainless steel spokes on squared heads. It is the upgrade wheel on the order forms and the wheel in the Newton Ultralight package. It also covers the two sizes the Newton One does not, 25" and 26". It comes as the wheel with its handrim hardware, without a tire, tube, handrim or axle, so plan to move those across from your old wheel or order them with it.
Straight talk
Is it right for you?
A good fit if you
want to take weight out of the rear wheels
need a 25" or 26" wheel
run pneumatic tires on a Motion Composites chair
Look elsewhere if you
want the handrim to change with the tire still on (see the Newton One)
want a wheel that arrives with a tire and handrim fitted
want to fit it to a chair that is not a Motion Composites

What Motion Composites doesRepairs or replaces the part
Not coveredNormal wear and tear, misuse, improper installation or maintenance, and changes made without Motion Composites' consent
The owner's manual is the full warranty
The owner's manual for this product has its own warranty section, and that section is the complete statement of what Motion Composites covers, for how long, and what falls outside the coverage. Read it before you file a claim. If anything on this page differs from the manual, go by the manual.
Parts and accessories cannot be returned. Check the size, the side and the chairs it fits on this page before you order. If it arrives damaged or defective, tell us within 48 hours of delivery and we will get it repaired or replaced at no cost to you.
If something goes wrong
Call us first at 1-855-HIELINE. We file the claim with Motion Composites for you and get the covered part sorted out rather than handing you a phone number.
Is the price for one or for a pair?
For one wheel. Order two for a pair.
What comes with the wheel?
The wheel and its handrim hardware. The tire, tube, handrim and axle are not included.
Which size do I need?
The size on your chair now. Read it from the tire sidewall: 451 is the 20" wheel, 501 the 22", 540 the 24", 559 the 25" and 590 the 26". Changing wheel size changes the seat height and the wheel lock position.
Which tires fit?
Pneumatic tires in the matching size. The size is the number on the tire sidewall.
How is it different from the Newton One?
The Gravity has a double-wall rim, weighs 670 g at 24" and comes in 25" and 26" as well. The Newton One has a single-wall rim and lets the handrim change with the tire on.
What should I have ready when I order?
The serial number of your Motion Composites wheelchair. Motion Composites asks for it on every parts order. Send it to us with your order number after you check out, and we match the part to the way your chair was built.
Will it fit a wheelchair from another brand?
Motion Composites publishes the fit for its own wheelchairs only, so we cannot promise it on another brand. Check the dimensions on this page against your chair before you order.
What is the warranty?
Motion Composites warrants its components for 1 year from the date of purchase against defects in materials and workmanship. Normal wear and tear is not covered.
Can I return it?
No. Parts and accessories cannot be returned, so check the size, the side and the fit before you order. If it arrives damaged or defective, tell us within 48 hours of delivery.
Is Hieline an authorized Motion Composites dealer?
Yes. Hieline is a Motion Composites dealer and orders Newton parts directly from Motion Composites, which makes them.
