Rear, Mid or Front Wheel Drive Power Wheelchair: The Difference Between

Looking to buy a power wheelchair? With so many models, colours, sizes, and brands, choosing the right one can be tough. One important factor is whether you want a rear, front, or mid-wheel drive. Each type serves the same purpose but has different pros and cons.

In this post, we’ll explain the differences to help you make the best choice.

What Are Drive Wheels for Electric Wheelchairs?

Drive wheels, powered by the electric wheelchair’s motor, move the wheelchair and affect its performance on different terrains.

Rear Wheel Drive Powerchair (RWD)

RWD power chairs are known for their stability, making them ideal for outdoor use. With drive wheels at the back, they provide good control on rough terrain. This setup gives a natural driving feel, like traditional rear-wheel drive vehicles, with the pivot point at the rear. They are best for people who need stability, spend time outdoors, or have limited upper body control. These chairs are easy to operate due to their inherent directional stability.

Benefits

Stability: Rear drive wheels provide a stable base, especially at the front of the chair, reducing tipping risks.
Efficiency: The design delivers strong torque, easily handling inclines and hills.

Considerations

Turning Radius: RWD chairs may have a larger turning radius, which can be a problem in small or tight areas.
Maneuverability: Despite design improvements, RWD chairs might not be as agile as other types in confined spaces

Mid-Wheel Drive Powerchair (MWD)

The MWD is a new drive wheel position that combines the benefits of front and rear-wheel drives. MWD power wheelchairs offer both stability and manoeuvrability with drive wheels located beneath the user. This setup allows for a tight turning radius and better indoor navigation.

MWD wheelchairs are ideal for beginners as they are easy to control. The turning axis aligns with the body’s midline, resembling natural walking motions. When turning around a corner, the process starts as your body reaches the corner of a wall, similar to walking.

This type is perfect for navigating tight spaces, such as at home or indoors. Unlike front-wheel drives, MWD users need some upper body strength and agility for precise control.

Benefits

Turning Radius: MWD chairs excel in tight spaces with the smallest 360° turning radius among the three drive wheel configurations, making them ideal for maneuvering at home or in small areas. They can turn on the spot and are perfect for indoor use.
Precise Maneuverability: The central wheel position offers a stable and controlled ride, improving manoeuvrability.
Stability: With six wheels in contact with the ground, mid-wheel drive wheelchairs offer excellent stability on inclines and ramps, both going up and down.

Considerations

Outdoor Performance: MWD chairs work well indoors, but they may not be as stable on uneven outdoor terrain as RWD chairs.
Bumpy Ride: MWD chairs have six ground-contacting wheels, which can transfer more energy from the terrain to the user. When hitting a bump, you might feel it three times, unlike the two times with RWD or FWD setups. This can affect ride comfort, but many manufacturers offer suspension systems to reduce the impact.
Traction: MWD chairs might struggle in outdoor settings due to “high centring,” where drive wheels lose traction and can’t move. This often happens with rolled gutters. Front castors climb the gutter, rear castors stay on the ground, and drive wheels lose traction, preventing the wheelchair from climbing. Many manufacturers now offer technologies and suspension to address this issue. If you’re considering an MWD wheelchair, it’s important to test it in outdoor environments, especially if there are rolled gutters.

Front-Wheel Drive Powerchair (FWD)

The FWD power wheelchair is perfect for indoor use and outdoor adventures. Its larger drive wheel can handle uneven surfaces before the smaller casters. The front wheels, connected to the drive motors, pull the casters over obstacles and through different terrains. Unlike wheelchairs with front casters, this design helps users overcome obstacles. Front-wheel wheelchairs provide good traction and allow close access to surfaces. They are helpful for those with limited upper body strength or dexterity, as the chair can pull itself over obstacles.

Benefits

Manoeuvrability: FWD chairs turn well in tight corners and indoor spaces due to their compact design. They can make sharp turns and easily navigate narrow passages. While they don’t have as compact a 360° turning radius as MWD chairs, the smaller front turning capability is often more useful.
Getting close to items: FWD wheelchairs allow users to get closer to objects like bathroom sinks. The drive wheel at the front helps the wheelchair pivot effectively, improving accessibility and interaction. This makes FWD ideal for situations where proximity to objects is important.
Obstacle clearance: FWD wheelchairs handle obstacles like curbs better because of their larger front wheels. The drive wheel diameter is 14″, compared to 7” to 10” caster wheels in MWD or RWD. This allows FWD to clear larger obstacles.
Traction: FWD wheelchairs perform well on inclined surfaces and provide good traction.

Considerations

Stability: FWD chairs may be slightly less stable than RWD chairs, especially on uneven terrain, but an adjustable suspension system can help enhance stability
Outdoor Performance: FWD chairs can handle most outdoor terrain, but RWD chairs perform better on challenging surfaces.
Turning Radius: FWD chairs might have a larger turning radius than mid-wheel drive options for 360° turns.
Manoeuvrability: FWD chairs are less nimble indoors compared to mid-wheel drive chairs but can still navigate indoor spaces well.
Learning Curve: FWD wheelchairs are a bit like forklifts with the rotation axis at the front. They are not as intuitive to control as MWD or RWD, but most people can learn quickly with practice and tips.

FAQs

Which wheel drive is better?

The best wheel drive depends on your needs and environment. Mid-wheel drive (MWD) offers excellent turning in small spaces but may struggle outside on uneven ground. Front-wheel drive (FWD) handles obstacles well and provides good accessibility but can be less stable. Rear-wheel drive (RWD) is better for outdoor use and offers solid traction, though it needs more space to turn. Consider your daily activities and test different types before deciding.

Is rear-wheel drive good in the rain?

Rear-wheel drive (RWD) wheelchairs can perform well in wet conditions. They provide excellent traction on damp surfaces due to their design, which places more weight on the rear wheels. This additional weight helps the drive wheels maintain contact with the ground, reducing the risk of slipping. However, be cautious when using RWD wheelchairs on wet or smooth surfaces, as they can still be slippery. It is important to test the wheelchair’s performance in rainy weather to ensure it meets your needs.

Why do wheelchairs have small front wheels and big back wheels?

Wheelchairs have small front wheels and big back wheels to improve their stability and manoeuvrability. The large rear wheels help users push themselves forward with ease. Small front wheels allow for navigating tight spaces and turning corners smoothly. This design makes it easier to operate the wheelchair indoors and outdoors.
