The Radical Cyclone IV Chubby trailer is an extremely versatile trailer with a padded bag that can be used to travel with a folding bike and then roll off into the countryside.
While it is specifically designed to fit a Brompton Folding bike, it doesn't need to be used with a Brompton. The bag is large enough to fit a number of folding bikes and the very slick hitch system will work with a huge variety of bikes.
The tires for the trailer are the same as for the Brompton so you don't need a separate spare - and you can use the trailer tire as a spare for the Brompton in an emergency.
