Power All Terrain Wheelchairs

In recent years there have been exciting developments in the world of power All Terrain Wheelchairs (ATW’s), mainly due to users pushing the boundaries and wanting to get out into the real outdoors. The new four-wheel drive chairs are built to cope with extreme conditions, but always come with a compromise in other areas, such as the difficulty of transporting them or their use indoors. Some are designed to be more versatile so, whilst they don’t do the extreme conditions quite so well, they do have benefits in other areas.

There is a fine balance between the wheelchair design, the power of the motors, the electronics used and the size of the batteries. When you run big powerful motors, you need big and powerful batteries to support them; otherwise you will be stranded after a short distance with flat batteries.

Many ATWs are now available with a Tilt-in Space function – which is particularly useful for steep downhill’s as it prevents those users who have no balance from falling forward. ATW’s are available in front-wheel, mid-wheel, rear-wheel and four-wheel drive. Each drive system comes with advantages and compromises.

  • Front-wheel drive gives good rough terrain performance as it pulls the wheelchair through rough or soft areas. They usually have large front wheels, and a reasonably small turning circle should you wish to use it indoors. The front-wheel drive chairs are difficult to steer and the speed is limited as the rear of the chair tends to fish tail at higher speeds. Some of the top end chairs have clever electronics to control this.
  • Rear-wheel drive chairs are popular as they are easy to steer and get a good top speed with a reasonable turning circle – depending on the length of the chair. On uneven ground, the castors stick easily - particularly in soft sand or rocky ground, unless they have very large castors, which will then increase the turning circle. Free swivelling castors tend to throw the steering on rough ground.
  • Mid-wheel drive chairs have a very small turning circle and a very direct response to steering, making them easy to steer. They have six wheels, of which the two large central ones are the drive wheels. These chairs are generally very stable and successful All Terrain wheelchairs, depending on the technology used to keep traction on the four smaller wheels. They handle curbs and other changes in height; (heights dependant on the limitations of the chair). The four small wheels sometimes limit the use over rough ground.

Four-wheel drive chairs are the best, with phenomenal performance over rough ground but they are big, with a very large turning circle making them difficult to transport or use indoors and are usually more expensive. If you want to do serious outdoor exploring, the reliability of the chair is crucial. Remember: you get what you pay for!

Most joystick controls programme easily and can be set according to client needs. Features such as sensitivity, how quickly it accelerates and brakes, and the angle of movement required for forward motion all impact on how the chair responds and how much pleasure you will get out of it. So, when buying. your ATW, make sure that the company sets it up to your liking.

When selecting an ATW you need to prioritise your needs. Consider:

  • The distances you travel dictates the battery size you need.
  • How you transport it will dictate the size of the chair unless you select one that can be easily dismantled.
  • Type of terrain – beach (soft sand), mud, gravel, rocks, gradients, water crossings, and thorny areas – these terrains will determine the power and torque of the motors required and wheel size - particularly the front wheels.

4 Wheel Drive

X8 Extreme - This is the Land Cruiser of 4x4 wheelchairs! It is reliable, comfortable, beautifully finished, and just does the job without any fuss. Very few obstacles were a problem in testing. Where other chairs got stuck on our test route, the X8 just powered over them, thanks to efficient gearing and the high torque of the in-line motors. Steering is controlled through a passive steering system, giving optimal and sensitive control even over rough ground. Optional front-wheel steering lock assists on soft sand or loose rocks. Available with modular seating options from a basic captain’s seat to a fully integrated power seating system. Mobility One 0861-662-454 from R109.000

Predator - At half the price of the X8, the Predator is an affordable imitation. Do not expect the same performance, finesse or reliability but we were suitably impressed with the performance that it offers at the price.
