Using a manual wheelchair doesn’t have to mean relying solely on your own pushing power. Power assist devices can lighten the effort, make everyday movement smoother, and open up new possibilities for independence! Whether you’re a wheelchair user exploring your options or a clinician new to the industry, understanding the different types of power assist — and how they can be controlled — helps in finding the right fit.
Quick Glance: Comparing Power Assist Types
| Assist Type | Best for | Key Perks |
|---|---|---|
| Hub-Mounted | Smooth, every-push assistance | Seamless boost, customizable settings |
| Rear-Mounted | Lightweight, flexible control | Easy removal, versatile control options |
| Rear-Mounted + SwitchControl | Custom control and sleek design | Programmable, tactile, wearable compatible |
| Front-Mounted | Rugged outdoor use and obstacle navigation | Easy attach, terrain handling, enhanced autonomy |
Drive wheel configuration can influence stability, maneuverability, and how the chair responds to the drive inputs you give. All of these are important to consider with any drive control, but when using an alternative drive control, there are some additional things to think about as well.
Hub-Mounted Power Assist
What it is: Motors and batteries are built directly into the wheels. The system kicks in when you apply force to the pushrims, activating sensors.
Why it's great:
- Every push is enhanced—no extra effort needed.
- Fully customizable with settings for speed, boost, and slope handling.
- Exceptional for rolling across varied surfaces effortlessly.
Things to know:
- Adds weight—up to 22 lbs per wheel.
- May require wheel removal for transport.
- Additional frame modifications and care in tight spaces may be needed.
Front-Mounted Power Assist: Growing in Popularity
What it is: A powered unit that attaches to the front of your wheelchair, lifting the casters and turning your chair into a “trike-style” setup.
Why it’s great:
- Handles rough terrain, grass, and curbs with ease.
- Quick to attach and remove.
- Reduces pushing effort outdoors.
Things to know:
- Adds length to the chair, which can make tight spaces harder to navigate.
- Slightly heavier and bulkier to transport than some rear-mounted options.
- Works best outdoors rather than in smaller indoor environments.
Rear-Mounted Power Assist
What it is: This lightweight, flexible option connects at the wheelchair axle. It gives you power on demand—then disengages to behave like a manual chair when not in use.
Why it’s great:
- Easy to remove and transport.
- No major changes to your wheelchair setup.
- Programmable for speed and performance to suit your environment.
- Minimal drag if the battery runs out or device is off.
Things to know:
- Requires learning a new control method (switch, wearable, or app).
- Works well indoors and outdoors but may need extra traction on steep or uneven terrain.
- Battery life depends on user weight, terrain, and settings
- Adds a small amount of weight to the chair, though generally lighter than hub-mounted options.

Clinical Tip
If you’re a clinician advising someone new to power assist, here are some things to consider:
- Start with needs, not features: Does your client need easy transportability, intuitive controls, or discreet design?
- Highlight flexibility: Review how each Power Assist device could offer or not offer a solution that adapts with the user's evolving needs
- Emphasize training: Programming and teaching users how to leverage these options means better adoption and more independence.
Final Thoughts
Power assist isn’t one-size-fits-all—and that’s the real advantage. Today’s devices offer a variety of control options that can adapt to different abilities, preferences, and lifestyles. Whether someone prefers a simple switch, a wearable tap, or a sleek, customizable interface, there’s a solution to help make mobility easier and more empowering.
