My husband & I just got back from cycling the first half of the TransAm: Oregon coast to Pueblo, Colorado. Pueblo to the east coast next year. Don's 60 with COPD, lung lymphoma, 2 new knees, and a new hip (the COPD is the issue as far as riding). He rode a 2011 Trek FX+ electric assist bike, me a 20 year old Raleigh mountain bike. We rode 40-50 miles a day, all motels, no camping gear.
