If tyres, inner tubes or handrims need to be
replaced, please contact your rehabilitation
specialist retailer.
Please note that changing one type of tyres to
another size is only possible with versions with
adjustable caster-wheel bearing blocks (cannot
be retrofitted), as with welded caster-wheel
bearing blocks the frame design including the
alignment of the caster-wheel bearing blocks is
precisely aligned to the tyre size ordered and
the welded caster-wheel bearing blocks cannot
subsequently be adjusted.

We recommend: The spoke guard
prevents hands and fingers entering and being
trapped in the wheels when riding. The risk of
injury is thus minimised.
