Customer Reviews
Der Volt selbst ist in der Tat sehr leise, und läuft sehr vibratonsarm. Die Ketten/Schaltungsgeräusche sind daher die Geräuschmacher und fallen entsprechend auf. Die Trainingssimulation habe ich mit Rouvy getestet, das dynamische Verhalten bei Lastwechseln ist sehr gut gemacht, es macht auch Spass damit auf hügeligen Strecken zu trainieren. Die Standfestigkeit ist gut, beim Volt ist das vordere Standbein rechts etwas länger, daher ist das Bike zentriert aufgestellt. Der Volt ist nicht zusammenklappbar, macht diesen Nachteil aber durch eine steife Schweissverbindung wieder wett. Die App ist nicht so intuitiv wie erhofft, aber es gelingt dennoch den Volt schnell zu verbinden und zu kalibrieren. Fazit: Empfehlenswert
