I have a Brompton electric. Not cheap, but happy so far and a great value being foldable. Bring it to the office and put it under your desk. In case of problems (heavy rain, flat tire) you can easily get it into a bus or inside the trunk of an uber/lift. Try if beforehand because being smaller tires it is a bit twitchy. Two dealers in Seattle: Montlake Bicycle Shop and Electric Lady Bicycle Shop.
