Stairs are no obstacle for this wheelchair. The wheelchair is equipped with three interconnected wheels on each side, allowing it to roll over edges. The wheel design allows easy installation and removal. This means it can be conveniently stowed (for example, during car transport). It can also be mounted on other wheelchairs, giving the user flexibility. More than 30 igus® clevis joints and folding spring bolts provide the required flexibility, with high reliability and low weight.
