As an absolute highlight from the Kettler Alu Rad Quadriga series, we present the Quadriga Duo models for the 2020 season. The brand new Kettler Alu Rad Quadriga Duo series with Bosch Performance Line Cx motor and two integrated Bosch Powertubes sets new standards. Even in the Wave frame (low entry), 1,250 Wh are installed for the first time. A unique selling point in the bicycle and e-bike industry. With it you can bring incredible ranges behind you. Optionally equipped with continuously variable Enviolo or 12-speed Shimano Xt derailleur, the series also shines in the selection of suspension forks and shocks. For even more safety and more stable driving behavior, the special extra wide 1.8 Mass at the head tube was designed. You benefit permanently by significantly more pleasant steering and driving behavior, a special development for e-bikes.
