Sunset as mentioned above used to be a very good shop, though my contact with them was back in the '90's so may have changed somewhat.
Other even less useful imput would be to teach her to mend a puncture, make a short film for her to copy of you doing it? cant imagine much else going wrong with the bike apart from that really.
There is this place that the Uni use that may be of use, teach too -
