The further back the rear wheel is attached, the longer the wheelbase and the greater the
wheelchair stability.

wheels can then also be lifted more easily to clear obstacles such as steps.
To adjust the horizontal position of the rear wheel, first remove the countersunk head screws
(Fig. 43, item A). Choose the desired position (Fig. 43, item B) and reassemble the screws.
Ensure that the left and right rear wheel adapters have the same horizontal position in the frame.
