Rotwild was at Riva Bike Festival this week-end to present its 2014 catalog and two prototypes of e-bike. The german premium manufacturer has already an e-bike in sale but engineers wants to push the concept in an other dimension.

Two bikes were presented – a 29er hardtail as you can see below and a 140mn full suspension bike (27.5) focused on the video.

For a time, this is not the Bosch but Brose which equipped the bike. Efforts has been done to integrate the battery onto the frame. The system Brose was already identified on some Cube Bikes with batteries inside the seat tube. Rotwild chooses to do the job in the downtube for both reasons of making and balance of the frame.

Result on the two frame looks good, the downtube is oversize but doesn’t disturb the design of the frame.
