I have a friend who's been pedaling to work for about 5 months now. The commute is just a little too long for him. It's been taking him an hour and 10-20 minutes to go each way, and he's been exhausted all the time. After I bought my Ezip, he started to get interested. I kept giving him stats on rides and info about the bike. A few weeks later, he bought one. He got it this week, and it has cut his commute time by 30-40 minutes each way. He's still pedaling, breathing hard, and sweating, but not for so long. He seems pretty happy with this solution right now.
Meanwhile, I've noticed a lot more motorized bicycles on the road in the past year. There is also a shop that popped up to deal scooters and electric bicycles ("real" electric bicycles and not scooters disguised as bicycles).
I love to see all these changes. More and more people are getting a clue.
