My Kalkhoff Agattu C8 Impulse HS (2013) was stolen a few months back (reported to the forum) and never expecting to see it again I replaced it with a Kalkhoff BS10. Amazingly a few days ago the police recovered the Agattu and so I now own 2 Kalkhoff e bikes! One will be sold and I am not bothered which. The BS10 is like new (obviously) and the Agattu is truly in first class condition - including battery capacity (just needs a new battery lock as the thief smashed the cylinder out). For any "doubting Thomas's" out there, both bikes were bought by me from 50 Cycles and all purchase documentation is available. I am located in West Yorkshire.
