The most significant change of all is the electronic control system. This uses the very latest in micro-processor technology with a host of advanced safety features. The ergonomically designed handlebar control is a direct replacement for the standard wheelchair handlebar grips and the easy-to-use controls feature very important handlebar extensions and optional left or right hand use.

The key which operates the on/off switch is removable for safety and security. There is an on/off light with red, amber, green colour sequence advising battery condition, a pre-set speed control governing top speed and a thumb-operated speed control lever. Alternatively the lever can be used in conjunction with the pre-set control to provide simple press button operation. The range has been expanded to include three models.

The standard single wheel version capable of transporting up to 18 stone user weight. The standard twin-wheel model with the same user weight limit but much greater traction – really effective on loose gravel and wet grass. The heavy duty version is only available with twin wheels and is capable of transporting up to 26 stone.

All of the fittings have been improved for greater ease of use and the Powerpack attaches to any wheelchair in literally seconds. Once fitted you will never need to push the chair again. Simply walk behind with your thumb on the control and let the Powerpack do all the work for you. No more struggling up hills, ramps or uneven ground; just press the lever and enjoy the effortless transportation the Powerpack provides. With speeds up to 4mph and a range of up to 10 miles, there is more than enough capacity for most days out.

It’s light enough to take anywhere, packing neatly into a travel bag and enabling you to have that extra mobility from car boot and coach, to train, boat and plane.
