This illustrates the device of how the fanner can bike to fan the fannee.

It can be stationary and portable!

The idea of a built in fan is already made so a directional device to guide the wind is all that is needed.  Below is an example from a stationary bike.  Also, the stationary rowing machine has a built in air/fan assisted to help cool down while working out.
