"After more than 3,000km in China with a lot of mountains, gravel roads and fantastic food, we're convinced our new Mocha is a great one. In Tibet we climbed up to 4,700m and raced down again. The brakes did their job perfectly. Now we're preparing for a ride across the Australian outback. Thanks a lot to the Co-Motion team for this great tandem." Niko K.
