I was on my way to work a few weeks ago and a roadie passed me. He had been chasing me for a while. I didn't pedal any harder, I was just kind of cruising to work. There's a mile long downhill grade and then a mile long slight uphill grade. I slowly closed the gap going up the hill and caught up with him at the top and he was dripping sweat and clearly out of breath. I was overdressed in long pants and a long sleeve shirt and talked to him a little bit while we waited for cross traffic.

I think it may have been then that he realized I had electric assist. =)
