Does anybody no what the score is with taking an electric bike in a bike bag on a flight as checked baggage?? I hear that some airlines refuse electric bikes because of the dangers with the batteries.
I have and actually carried an E-bike to India from Washington DC.
Qatar airlines was really friendly. One sporting equipment is allowed free of cost.
You could keep the batteries in your carry-on baggage as long as it's less than 100Whrs. If you're lucky, they will let you carry more and they may not question you.
Even though I had put lots of foam, padding, the rear wheel axle was poking out of the box. You could buy Aircaddy ( pretty good cardboard box) or use your own.
