Your best bet may be to fly to Portland and rent a car for the week. Drive to Eugene and pick up your Bike Friday. There is a very nice bike path of several miles right behind the Bike Friday factory. Spend a day or two in Eugene as there is a good choice of 20-30 mile day rides. Then work your way back north to Portland with stops in Albany/Corvallis area and McMinnville/Forest Grove (heart of wine country) for a couple of days each. There are great day rides in each of these areas, as well as motels and B&Bs along the way. Take the scenic routes north rather than Interstate 5 (you could even follow the Willamette Valley Bikeway, but by car). You could leave yourself a couple of days in the Portland area to sample the Columbia Gorge scenic area before returning to Toronto. If you want to sample the coast and ride there, you could get there within 1-1/2 hrs by driving west over the coast range from any of the above towns.
We use our Pocket Crusoes around town (Corvallis), for Saturday club rides and for occasional 25-40 mile picnic rides around the valley. We also haul them around in our car for day rides whenever we go on longer trips.
Hope this helps.
