We're about to fly in about 12 hours and the friend who gave us our Micralite Fastfold doesn't have the instructions and never had to remove the back wheels herself. We suspect we'll have to take them off at the airport for stowing (cheap airline!) and have NO idea how to do it. I guess it's something to do with the little silver clips but nothing seems to happen when we pull them. If anybody can help in the next couple of hours I'd be INCREDIBLY grateful! Thanks!
