The SE Concept Bikes are completely rebuilt and restored motorcycle conversions, including engine, transmission and electrics. We offer 4 genres: the classic cafe racer, the versatile roadster, the all-round scrambler, the old school bobber and the robust enduro.
We provide the base vehicle and take care of the TÜV inspection after the upgrade/conversion. The condition after completion corresponds to that of a new motorcycle. The bikes are delivered with one year warranty.
