Article sem to suggest an update to the Ebikemotion X35. They've added the "Plus"to the name. Looks like an update to the software, battery connection, and speed sensor location. Not much more info besides the changes to the bike itself.
"And now there’s a small update called X35+, which is supposed to offer extended connectivity like ANT+ integration (although this was already partly available in 2020 models). On the hardware side, the motor housing and system design have been further improved, and the new motor also allows higher spoke tension for more robust wheels. A small but perhaps important point, as we read about spoke breaks on Orbea’s popular Gain models from time to time. All the other components of the system remain unchanged."
