We built the Stereo Hybrid ONE44 to be as adaptable as it is capable. With its compact 800Wh PowerTube battery and powerful Bosch CX drive unit with up to 120Nm of assistance, it features 140mm of front- and rear-wheel travel and includes space for mudguards. Internal Cable Routing flatters the frame's clean, organic lines. There's a set of SIC 2.0 mounting points for the addition of an optional luggage carrier, the UDH dropout is future-proof and the Direct Mount chain guard is neat and unobtrusive. Plus, with Size Split, there's a frame to suit almost every rider.

We built the Stereo Hybrid ONE44 to be as adaptable as it is capable. With its compact 800Wh PowerTube battery and powerful Bosch CX drive unit with up to 100Nm of assistance, it features 140mm of front- and rear-wheel travel and includes space for mudguards. Internal Cable Routing flatters the frame's clean, organic lines. There's a set of SIC 2.0 mounting points for the addition of an optional luggage carrier, the UDH dropout is future-proof and the Direct Mount chain guard is neat and unobtrusive.
