At the entrance, off suthep road, of the airport the military has a sentry post and road barrier. One day i was stopped and refused entry to the road. I was on a bike without a helmet and offered to walk but not permitted. Who can use that roadway as i may wish to try again. My destination was the golf course, Star Dome.

NO HELMET! Did the guard have a helmet? Is it the law in Thailand?

Information can be found in the below links, first one directly pertinent to the op. Bottom line, you need a Wing 41 sticker to pass through. Yes I know, some have managed to do it when the guard wasn't looking.

Did the OP mean push bike? AFAIK it is motor bikes only(and cars) that can get stickers - no walking, no push bikes.
