I'm an rather old guy of 70+ but still going strong if I was still 70. ;-) I ride the Haibike adventr ebike with the speedbox 3.0. But after half a year riding around wit fast pleasure I get an issue with an error code 504. As another guy here on the topic already did have the same issue , just waiting for the green traffic light , suddenly the 504 error code appeared on the display. Back home with a top speed of only about 17 kmh (.) I did check the connectors, wires etc. Nothing wrong with that. All parts are clean and looking still as new. Is some one familiar with this issue and if so, what could be the solution ? Tnx !
