I was thinking more inline with the original picture I share.......a detachable modification which can be removed with ease, and rather than putting in those big fuggly fans I was hoping to install these:
Yes these 12v DC fans....the one you find in your desktop. A relative of mine have installed these in his Suzuki Bolan (Hiroof) and they work just fine. They will reduce the safety hazard and will require less electricity so maybe I wont even need to change the battery with a bigger one. I thinking of 2 fans above the head.
Your suggestion is way to fancy and complicated. Itna time hota tow I would be working on the project I have on hold. The 2nd picture you shared is of a really pretentious motorcycle..... u know when you have stop on the signal..... the supporting wheels come out of the sides automatically to stop the bike from falling........ If I try this with my skills.......I wil be falling on every single traffic signal of karachi.
