The rear wheels have a diameter of 550 mm.
They are equipped with spokes and handrims.
They can have pneumatic tyres or solid tyres
and can be connected to the side frame by
means of a fixed axle or a quick release axle.
In case of a puncture, the tyre has to be
removed from the rim. Press the valve to let all
the remaining air out of the inner tube. Pull the
tyre off the rim. Repair or replace the inner
tube. Put the tyre back on the rim. Inflate the
tyre to the required pressure.
- Note: It may be necessary to use one or two tyre removal tools (not
supplied).
Handrims
- The handrims are used by the user to drive
the wheelchair.
- NB: As the handrims are in contact with your
hands, make sure that they are not damaged
and that the surface has no parts which might
cause injury to the hands.
- Adjustment: No adjustment is required for the handrims.
