We, e-bikers are affected by the wind on our rides as any other cyclist. While traditional cyclists get exhausted by countering headwind, the same phenomenon makes our assisted rides not only slower but also the battery range gets significantly shortened, especially if we ride one-way (e.g. for a commute).

While we cannot do anything to cancel the headwind drag, we can plan our long trips smarter. For example, selection of the recreational loop route could be planned upwind for the outbound ride segment (when we are fresh and the battery is full) to return as if we were "sailing" with the tailwind, at lower assistance, and gaining many watts from the wind power when we are already tired. Doing opposite, that is, riding out with the tailwind and returning against massive headwind might have caught us with the trousers down! Fancy returning home on a flat battery upwind on a heavy e-bike!

I use to plan my leisure/fitness/recreational routes using possibly trustworthy weather forecasts. However, the inability to measure and quantify the wind on my rides has been always irritating me. I used to watch weather vanes, flags, trees to determine the wind direction and strength. I was turning my head around to determine the actual wind direction (if you can hear the wind in both ears, you are spot on the headwind). Still, I could not measure the wind speed.

What about an inexpensive and lightweight electronic anemometer to be carried in a pocket or a backpack? Thougths?

Working! 5.8 km/h NNE. It is a weak wind. And it felt so cold and unpleasant on my ride to collect it!

I have one from my dirtboat days, but it has no current value to me. WIndy when riding, I get slowed down.

You simply do not set off for such long trips the wind speed would matter for you. And you use the throttle.
 
I referred to another thread. Of course the Srafang would work up massive headwind. The point is, the battery would not last for 62 miles, especially as the Srafang Srike would be ridden on the Srottle.

I can easily get 62 miles unless we are talking hurricane winds.
And I can honestly say that I have NEVER used the throttle to counter headwind.
You may better understand this if you removed your head from your one track, echo chamber ass.
 
Let us make a bet.
I'm going for a 90 km (56 mi) ride this Saturday. I bet you won't do the same. (If you want to win, document your ride).
 
If you win (that is, ride & document it), I will admit Bafang are good motors. If you don't, you will stop trolling my threads.
Deal?
 
People think I'm anal because I watch cadence. Makes no sense to me to carry a weather station. Weather app gives me a good enough idea what is going to happen during the day. If it changes, maybe I will also.

Although we do have a weather rock in our yard.
 
Well... Sailors, mountain climbers, drone operators, etc. use anemometers. Why shouldn't an e-biker use it?
