You are the first person I have heard comment that you can feel the drag with a Sinewave.
Someone on the touring forum board has commented that he could feel the drag from the Forumslader, but that charger can produce a lot more watts than the Sinewave at touring speeds, so that does not surprise me.
Riding near home, I have dyno powered lights on several bikes, and I usually leave them on during daytime because I can't feel any drag from them so it does not noticeably slow me down. I know there is drag, but it is so minor, I can't feel it. My Sinewave is on my randonneuring bike, that has 32mm tires that have very low rolling friction,
I think the additional drag on my SP PV8 hub wtih lights on is about 4.5 watts more than with lights off at about 20 km/hr, but that is a small enough amount of extra drag that I can't feel it.
