Notes

In order to alleviate hemorrhoids, the big driver made such improvements in his seat.
Hemorrhoid Treatment

Craftsmen who drive long-distance large commodities know that the most painful thing is not driving sleepy, nor is it basking in the sun and raining. The biggest headache is the pain of the sedentary lumbar spine and cervical spine. The other is that the ass is wet with sweat for a long time, which is easy to grow hemorrhoids. Truck owners want to breathe through the ass. (David Asher).
In order not to sweat all day, most people choose cushions that penetrate the air, but they are useless in hot weather.
Some riders put small fans on their cars. There is air conditioning, but there are small fans that increase airflow and guide air into the back and hips. That's good, but many places don't blow.
The cyclist's real talent is to collect air from the window through the natural wind and transport it directly under the seat through the pipe. There are still changes, but they must be installed correctly. After all, the airflow working at car speed can easily blow away the device.
Although it is high-grade, it is not natural wind, but the air conditioning wind that guides the vent directly under the cushion.
Some riders thought the air duct was blocking the road and changed under the seat cushion. Three small fans are installed under the cushion, hidden wires and introduced igniter charger. This is a clever high-end way.
It is the local tyrant's way to directly replace this luxury multi-functional seat, but no one spends 10000 yuan to buy such a multi-functional seat that is warm in winter and cool in summer.
