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 features a Bosch Performance Line Cx motor and two integrated Bosch Powertubes, setting new standards. For the first time, 1,250 Wh is installed even in the wave frame (low step-through). This is a unique feature in the bicycle and e-bike industry, allowing you to achieve incredible ranges. Equipped optionally with a continuously variable Enviolo or a 12-speed Shimano Xt derailleur, the series also excels in the selection of suspension forks and dampers. For even more safety and stable handling, the specially designed extra-wide 1.8 measurement at the head tube has been developed. This results in significantly more pleasant steering and riding behavior, a special development for e-bikes.
