eRebumbents are way more aero than DFs. Cross-winds, which are lower closer to the road, bents have lower cross-winds closer to the road.

I'm only a scientist.

But bear in mind, if you have a bent, you aren't getting as good a work out as with a DF for the same speeds.

Where I live, a lot of people ride with aerobars. I don't because they decrease the workout. I see people with electric drive-assist. They're faster than I, but their power is coming from electric motors. I think they are doing more for the environment than driving cars, and they are reducing our foreign-nergy dependence.
