There was a sidewind all day of almost 10 mph. What was interesting was the run with the tail was not only quicker (by 5 mph) but the bike felt more stable. You can see by the little flap at the back of the safety vest I was wearing that airflow looked improved, even when the vest itself is flying around (it needs to be adjusted better). The most interesting thing was the coastdown tests I did: I computed speed for 15 seconds (based on motor rpm) with regen shut off. The bike slowed down 13 mph more without the tail! I'm planning to make it streetable this summer and get real-world range and consumption data.
Thoughts, comments, etc. appreciated. Happy New Year!
