Hi there @SArmstrong !
Thanks for reaching out to the Community! The good news is that most pedals are interchangeable. This means that the threads on your current pedals likely match the threads on the Shimano pedals you referenced and can be used on your wife’s bike.
The best thing about those particular pedals is their versatility for sure. The dual sided design will allow for her to ride with cycling shoes or the footwear of her choice. Also, attaching the toe clips to these pedals should not be a problem.
Hope that helps answer your questions!
