Hi new member here, about 6 weeks ago purchased a voodoo bizango e bike great bike long story short the shop couldn't find the battery key so was told the new bizango e bike was coming out with the shimano steps motor so I ordered one and they did a straight swap, but been having error codes popping up which shut the motor down been in the shop twice but they have said if I want I can swap for the zobop ebike which I know the Bosch motor is more reliable but not as smooth as the shimano I'm stuck what to do
You might want to check with some of the Bosch experts here.
I myself saw lots of problems online here in Germany, with the early models, but apparently (I am told) these problems are fixed, but that is all "hearsay" when I say it, as I have never even ridden one....
Check the age/version of the Bosch bike with help here from the experts on Pedelec.
On the early Bosch bikes they had internally plastic gears and only a single chain externally, which apparently does not last long as all the electric and muscle power goes through the same "thin" chain....
I wish you that everything turns out well for you.
regards
Andy
