Powergrips are a great choice for a lot of folks. The model you referenced is a quality set-up. The pedal is light, has good bearings, and the spindle & cage are strong. I've used them for a number of years on both hardtail & full suspension mountain bikes and have recommended them to a bunch of folks - some of which use them on their commuter bikes. None of us have any complaints. I predict your wife will like them.
