Hamsters are able to eat cucumbers just like humans, though they may not respond to them as well. Cucumbers have been known to cause stomach problems in certain animals like hamsters as well as rabbits, especially if it is consumed in excess.

If you do choose to give your hamsters cucumbers, you will want to limit the amount you give them. Although it is true that there is nothing toxic in cucumbers, you will still want to avoid giving them this food too often, as it might upset their stomach and causing diarrhea or vomiting, which is a mess you will want to avoid cleaning up altogether.
