It would be a shame to have to leave it there. If the problem is the bag or box he'll be using on the flight out, it might be possible to leave that either in some left luggage facility quite cheaply or find a friendly bike shop in Delhi, make contact with them now and ask if they'll store it for a week or two, however long he's going to be out there.
But if he does have to leave it there, I advise also the friendly bike shop, or some club. A bike like that should go to someone who will appreciate it.
