Yes my Sondors has this issue, ordered an extra battery at the time of purchase and their was no option to have them keyed alike, I have different 2 keys for this Ebike, having the same key for all batteries should be on the list for future improvements, but it wouldn't be a deal breaker for me either.Curious - has EBR come up with the same issue on other bikes ? I am absolutely sure that all bikes with dual batteries (anything other than Bosch) - e.g. from Frey, Biktrix, Luna (if and when they offer dual) has the same issue. We are in kind of unchartered territories here due to the list of features we have here.
I have not seen that brought up as a big concern by anyone. I understand some of what we all discuss is personal taste and the multiple locks do not bother me. I consider it as a safety feature - more keys means it is harder to steal with one key. If someone has to steal your bike, a simple lock is not going to stop them - you definitely need like 3 levels of U Lock to secure this.
All that being said, the UC Pro has already exceeded the expectations I had set for myself. The new controller, added efficiency, better color options... those are things we didn't start off with back in April. Everything we are seeing here is just gravy.
At this point, I cant wait to just get on it and start riding.
