I am thinking of using a trailer for my next touring holiday. The problem I wish to overcome is the weight limit set by the airlines.

At the moment my suitcase containing bike and a few bits and pieces is 20kg ( the limit before charges start).

If I could add some wheels to utilise the suitcase as a trailer it would then contain my carry on luggage and the spares, a combined weight of about 10kg.

The lightest solution I can think off is to bolt on some kids trainer wheels and use one of the ingenious methods for a hitch from this thread.

The suitcase is a nice, solid number. Considering the light weight it will carry and the slow speed I trundle at, is it feasible or should I pack the bike in a cardboard box?

Look forward to any ideas and as somebody who has learned a lot from the regulars on these forums can I say 'Thanks.'
