The Extrawheel Voyager Solo is the lightest single-wheel bicycle cargo trailer in the world. Pack it up with panniers so you can carry more luggage and then take your bike anywhere. The Voyager excels off-road, making it the perfect trailer for bikepacking and long tours in tough terrain where riding on roads is not always an option.
That's not the only use for the Extrawheel though. Read about how useful it can be here.
