 Active Pozi-Trak drive system. (APT)
APT is a unique suspension system patented by Glide and was developed to enhance the performance of its latest Mid Wheel Drive wheelchair. The APT system is a three functional operation which increases traction on the Drive Wheels, aids with Kerb Climbing and acts as an Anti Pitch device. The suspension system also eliminates nose dive when descending road side kerbs.
The drive wheels are set positive meaning when the wheelchair is on a level ground a preload of up to 20kg (depending on spring set up type) is on each drive wheel. This unique system greatly improves traction for driving and braking. It also performs extremely well in emergency down hill braking.
This system is a very low maintenance system and has eliminated the need for complex moving parts that need constant servicing or adjustments. Also, with the combination of varying spring set ups, your wheelchair can be fined tuned to suit your driving preference.

e.g. Biased for more traction or increased kerb climbing ability.
