The Newton Grade Aid is Motion Composites' three position wheel lock: free, grade aid and locked. It is sold as a pair or by the side, on a standard or an extended rail, with or without a 6" removable handle.
The Newton Grade Aid is a push to lock wheel lock with a third position between free and locked. In that position the wheel rolls forward and cannot roll back.
What stands out
A grade aid earns its place on ramps and hills. Set the lever to the middle position and the rear wheel turns forward freely while the lock catches it the moment it tries to roll back, so you can stop to rest or reposition your hands partway up a slope without holding the chair. Push the lever the rest of the way and it becomes an ordinary wheel lock for transfers. Motion Composites lists the unit at 156 g and built the handle low so it stays out of the way of a sideways transfer. It bites the tire tread to hold, so Motion Composites suggests it with a pneumatic or high pressure tire. Order the pair or a single side, match the rail to the locks on your chair now, and set the gap to the tire at about 1 mm when you install it, as the instruction sheet shows.
Straight talk
Is it right for you?
A good fit if you
- push up ramps or hills and want to rest without rolling back
- want a wheel lock and a hill holder in one part
- have a Motion Composites wheelchair with pneumatic or high pressure tires
Look elsewhere if you
- use solid tires that give the lock little to grip
- need a pull to lock wheel lock
- want to fit it to a chair that is not a Motion Composites
