I am planning to travel in Europe (& in my dreams, beyond) using air, busses & rail - hopping off & biking around, then continuing on by air, bus or rail - so my folder has to be compact enough to carry on busses & airlines with minimum surcharges (hopefully none!) and able enough for me to explore at least 50 kilometer radius in each vicinity. I intend to use my Golite pack that I'll either wear on my back or strap down on a rack (less than 15 kgs) until I can dump it at a local no star hotel :)
So far my choice is a Brompton as it locks into folding position, is light weight, and from what I have read should be able to take some good punishment.
Any other suggestions or comments would be greatly appreciated
