The Helius Travel is fitted with a folding mechanism that allows it to fold away in its own special carry bag within a matter of minutes. This means it is easier to carry on public transport, on narrow escalators, and in cargo bays. Once you arrive at your destination the Helius Travel can easily be reassembled and the pack becomes a rucksack. Technically the frame is identical to the Helius CC but due to the folding action it must be run with a Rohloff ® hub only.
