Le sigle "RT" fait référence au frein à rétropédalage intégré, qui offre une sécurité supplémentaire aux amateurs de sensations de conduite classiques. Propulsé par le moteur dynamique Bosch Performance Line, ce vélo compact de 20 pouces est un compagnon absolument fidèle pour la ville. Grâce au concept intelligent de cadre One-Size, il s'adapte en un clin d'œil aux différentes tailles.
