I am not trying to set any records. I am curious more than anything.
I would love, however, to push my own efficiency as far as I possibly can. For me, the best efficiency I have ever achieved without any pedalling what-so-ever, is 13.4WH per mile at 18 miles per hour. I have heard numbers from guys here on the forum, of 15wh per mile at 20 miles per hour (roughly what my bike will do), I have heard 26wh per mile at 26mph. I have heard 9wh per mile at 10mph. etc.

14.12Wh/mi at 31.1 mph avg is what I did last year at the ePower Challenge in Portland, Oregon. I was the second fastest. The bike that was the fastest 24Wh/mi at 35.3mph avg was a Tour Easy with fairing and body sock. I'd love to have a small powerful light weight assist. Matt, I've been following the thread on your system and I would like to put one on my velomobile.
