Once the patent disputes are off the table, Gottschalk picks up the pace. The Rotax hub’s successes in competitive cycling soon bring it worldwide fame, and in the private sector, too, it becomes a synonym for quality and reliability. The popular bicycle magazines of the time carry favorable reports of its success in competition and also publish readers’ letters that illustrate the everyday benefits of the Rotax hubs.

“Touring cyclist Hugo Schöler, who is well known in many circles and who uses the Rotax freewheel hub, rode over the 2,436 m Furka Pass. He describes the journey, and above all the excellent functioning of the Rotax freewheel hub, with great enthusiasm. The accolades for the Rotax freewheel hub thus accumulate from day to day – one might even be tempted to say by the hour. Performance like this can only be achieved with a hub that really is made of only the finest materials, and whose construction guarantees ultimate longevity.”

“I feel compelled to express to you my full appreciation of the excellence and reliability of your Rotax freewheel hub. I covered 6,443 km in the space of 70 days with your hub and passed through many different countries. The regions of Bohemia, Bavaria, Tyrol and last but not least, Switzerland made great demands on the Rotax, and your hub achieved what would have been unthinkable in the past. Not a single repair was necessary and the Brenner road would not have been half as easy had I not had the Rotax freewheel. On the Brenner pass I reached speeds of 50 to 60 km/h and despite sharp braking on the steep bends, the hub did not even become slightly hot.”
