Rear Drive Unit Under a Folding Chair
A small drive unit sits under the seat of a folding chair and pushes it along when switched on.
An assisted wheelchair can mean a chair helped along by a small motor, or one designed for a carer to push. This guide explains both meanings and helps you decide which type of help you actually need.
“Assisted wheelchair” sounds precise, yet people use it to mean two separate things. Some mean a chair where a small motor adds power to each push, so the user or carer does less work. Others mean a chair designed to be moved by a helper, with push handles and small rear wheels, where the assistance comes from a person rather than a battery. Sellers and search results mix the two freely, which is why so many buyers end up comparing products that do not really compete with each other.
This page untangles the term. It explains each meaning in plain language, shows who each suits, and ends with a short set of questions to help you decide which kind of assisted wheelchair belongs on your shortlist.
In the first sense, an assisted wheelchair is a manual chair with some form of electric help. The chair keeps its normal frame and wheels, but a motor, battery and control are added so that pushing becomes lighter. This is often called a power assist wheelchair, and the equipment that provides the help goes by several names: a wheelchair power pack, a power add on for wheelchair use, or a wheelchair motor attachment.
There are a few broad approaches. Some systems build motors into the rear wheels and respond when the user pushes the rims. Others use a single drive unit behind the chair that pushes it along, often controlled by a small switch or wristband. A third group clips a powered wheel onto the front of the chair, turning it into something closer to a tricycle. Each changes how the chair feels and handles, so it is worth reading about them before buying.
Assisted propulsion appeals to people who can push a manual chair but struggle with hills, long distances or tiredness later in the day. It also helps carers who push a companion and find slopes hard going. Because the chair stays fundamentally manual, it is usually lighter and easier to transport than a full power chair, although the added parts do add weight.
In the second sense, an assisted wheelchair is one made to be pushed by someone else. These chairs are often called attendant propelled or transit chairs. They have smaller rear wheels without push rims, so the seated person cannot easily move themselves, and sturdy handles for the helper. Many fold compactly and are lighter than self-propelled chairs, which makes them popular for occasional outings, hospital visits and holidays.
The assistance here is entirely human. There is no battery to charge and nothing electronic to fail, but the helper does all the work. On flat ground that may be fine; on hills or long walks it can become tiring. Our page on the attendant propelled wheelchair explores this type in more detail.
The line between the two is not always sharp. A carer pushing an attendant chair can add a rear-mounted power pack, creating a chair that is both attendant assisted and power assisted. There are also attendant controlled electric chairs, where a companion steers a fully powered chair from behind. If a listing simply says “assisted”, read the description carefully to see which kind of help it means.
Putting the meanings next to each other makes the trade-offs clearer. A power assisted chair asks for a routine of charging, occasional servicing of the motor and electronics, and some care when lifting the heavier parts. In return it can make hills and long pavements far more manageable. An attendant assisted chair needs almost no upkeep beyond tyres and brakes, folds quickly and is easy to lend or take on holiday, but it relies on the helper’s strength every time. Cost tends to follow complexity, so a chair with motors and batteries usually sits higher than a simple push chair, though you should compare current listings rather than rely on assumptions. Think too about the future: if the helper’s own health or stamina may change, an option that can take a power pack later could be the safer long-term choice.
Working out which meaning fits your needs is mostly about who will be moving the chair and where.
A self-propelled chair with power assist usually suits best. The user pushes as normal, and the motor takes some of the strain. Independence is preserved, and the user can switch the help off on easy ground.
An attendant chair is the simplest option. If the carer struggles with slopes or distances, consider adding a rear power pack. Our guide to wheelchair power assist for caregivers looks at that combination.
A full powered chair may be more appropriate than any assisted design. Speak to a professional before deciding, as the choice affects posture, safety and transport.
Whichever kind you lean towards, a few questions help you compare listings fairly.
For a wider look at add-on options, see our article on choosing a wheelchair power add-on. If you prefer to compare simpler, human-powered chairs, the transit wheelchair guide covers the options.
Whether the help comes from a motor or a person, safety habits matter. With power assist, learn how the controls work on level ground first, and follow the maker’s instructions on slopes, braking and freewheeling. With attendant chairs, check the brakes before each trip, approach kerbs carefully and never tip the chair further than feels controlled. In both cases, keep tyres in good condition and look over the frame regularly for loose fittings.
If you are unsure which type of assisted wheelchair suits the person who will use it, a wheelchair assessment is a sensible step. The NHS explains how wheelchair services work on its page about walking aids, wheelchairs and mobility scooters. If you are buying privately, GOV.UK sets out when VAT relief on disability equipment may apply, so check whether it covers your purchase.
The word “assisted” tells you only that some help is involved. It does not say whether that help comes from a battery, a person, or both. Once you know which meaning fits your situation, the search becomes much easier: you can ignore listings built for the other kind of help and focus on the details that matter to you, from push rims and battery packs to handle height and folding size.
A small drive unit sits under the seat of a folding chair and pushes it along when switched on.
Rear wheels with motors in the hubs add help each time the user pushes the rims.
A front unit that clips on and lifts the castors, turning the chair into a powered three-wheeler.
Help aimed at the person pushing: an attendant pack fitted to a transit chair.
On its own, the front attachment shows its handlebar and single drive wheel.
The rear drive unit alone, with its small remote; ask how it mounts to your chair.
The drive unit lifts off before folding, so the chair can still go in a car boot.
A control on the push handle lets a carer start, stop and set the speed.
Batteries and chargers differ between systems, so check what comes in the box.
On an active rigid frame, thin motorised wheels give a helping push while keeping the sporty look.
