A thread on efficiency got me thinking about fairings.
I ran across this:
"Numbers on the topic aren’t easy to find, but some that are regularly cited are extracted from David Gordon Wilson’s Bicycling Science. He states that a rider on a touring bike equipped with a partial fairing, and his or her hands on the handlebar, would require 63 watts less (157w vs. 220w) to overcome air resistance at 35km/h when compared with the same bike and rider without. Huge gains indeed."
Wind resistance goes up exponentially with speed, so this could make a HUGE difference on an ebike...
Maybe I should get one of these...
