I was at the fair in "Friedrichshafen" 2013 and the e-KRAD is still "alive". It is not a commercial product, but the guys have built their own motor now "it has ~50HP" and they race it as a Supermoto against ICE bikes.
It is awesome fast and they are well-placed in all races.
Maybe I can visit the guys once, they live in the city where I grew up.
