Something that made me go hmmmmm
After dealing with a heavy dose of wind this week on the south Texas coast I was just wondering about something. Forgive me if this sounds like Jr high math word problem. If your traveling at a speed of 75mph into a head wind of 30mph is that a simulated speed/feel of 105mph? lol...just wondering.

I assume it would be. I know as a pilot of small aircraft that if you are flying at say, 105 knots airspeed with a 100 knot head wind, your speed over the ground will be 5 knots even though your airspeed indicator reads 105 knots. Conversely, if you have a 100 knot tail wind your speed over the ground will be 205 knots.
On your bike, you would need to increase the amount of throttle you are using to maintain your 75 MPH speed in a strong headwind.
Anyway, that's my story and I'm sticking to it unless someone else disagrees and makes sense.

Yep, you were doin a simulated 105 mph. Conversely, if you're riding at 60mph with a 60mph tailwind, you and your motor will feel virtually no wind which can make an engine overheat.

Try riding a road bicycle into a stiff headwind, yep, more power required big time.
Tail winds, of course, are much more enjoyable. That's when I raise up to go full sail, or you could say "High, wide, and handsome".

This is the reason a/c take off into the wind, less ground speed is req'd to lift.
If you're pushing a 40 mph headwind @ 60 mph then the relative wind speed going past your ears is 100 mph and it is very noticeable.
On the other hand a 40 mph tailwind @ 60 mph will give you a relative windspeed past your ears of 20 mph. On long hauls a tailwind greatly reduces buffeting.
