Oregon has a unique environment for cycling.

The weather is fairly temperate. So, relatively few snow or ice days in the winter. Some nights down to perhaps 20°F, but much of the winter is in the mid 30's. Yet we also have a wet winter and dry summer.

100°F is rare in the summer, but seems to be happening more frequently recently, with a lot of summer in the 70's and 80's, and often cooler in the evenings. There is, of course, some Urban Heat Zone effect.

So, it is very possible to bike commute 12 months a year, but one has to plan on rain in the winter (as well as the typical shorter days of the Northern Hemisphere).

There has been an effort to improve the cycling infrastructure in the city. It still is a big city, but many major arterials either have bike lanes, or good parallel bike positive routes.

Pedalpalooza is a unique annual cycling event in Portland. It looks like it is coming back to life this year.

There is a good tram that takes one to "Portland International Airport"... except, of course, most international flights come through Seattle, SF, LA, or various Eastern airports. So expect connections.

There are some good bike paths and routes outside of Portland. A good path/route up the Columbia Gorge. I've taken the "Willamette Valley Scenic Bikeway" between Eugene and Portland several times with the biggest issue that it is a little hectic getting from Portland to the beginning of the route at Champoeg St. Park.

You may wish to review your needs yourself. I've commuted in the Portland off and on, but also approach it as an outsider.
