Ok! I found the sticker.. or decal.. 250W only.. ok, It's EU regulations which demands here that you don't need any more power. But I am quite heavy and tall.. steep hills are quite hard to get up.. maybe during next winter I should open the motor and add some mosfets/stunts there and have some more power. Is there any change of motor during past few years? Is it still able to upgrade like adding those mosfets?
