Hi Im new to this but I wonder if any one can help . I have an AVE XH5 with Bosch Vituvia system . Its 2yrs & 3months old and has covered about 6000 miles . I did 30 + miles on it last Wednesday & put it on charge when I got home .Following morning it was showing only 80 % charged and had "forgotten" the last half of the previous trip . It was also showing no speed and was not giving any assistance . No screen fault codes showing . Took it to the local Bosch e bike dealer who plugged into their system ,which showed no faults .They are at a loss . can anyone make any suggestions or had anything like this . Any suggestions much appreciated !
