It’s a 2019. With the new hub sensor. note that this is different from previous speedbox 2 models—it is specifically meant for “Yamaha-branded bikes”

Just installed this on my Yamaha Cross Core and after a (brief, rainy) test ride it seems to work perfectly! Kind of a pain to install on these bikes since you have to remove the chainrings to drop the motor, but otherwise I had no issues. My order shipped from the Czech Republic and arrived...

I don’t have particular interest in this one, since I like having a speedometer, but when I have my bike apart to install the one that I bought I might take some measurements off the rear wheel sensor and see if I find anything interesting.

This is really interesting, it looks like an entirely different approach from the other tuning chips that I’ve seen. Instead of interrupting the signal between the wheel speed sensor and the motor (and presumably changing it to make the bike look like it’s going slower), it just removes the...

Yamaha CrossCore

I decided to go for it—ordered direct from the original link. Crossing my fingers!

On the original link that was posted, it looks like there’s an (albeit slow) option to ship to the US.

So, who wants to take the plunge first? ;)

Just speculating, but I suspect that the system on the Yamaha bikes is likely the same as that on the other 2018 PW-SE models, but with slightly different firmware to support the different measurements from the speed sensors. So when the devices designed for the magnet-on-the-spoke sensors try...

That's correct -- here's a photo of the motor connectors on my Cross Core: . However, the speed sensor is different (it's mounted inside the hub -- it's unclear whether that changes anything).

You might need to drop the motor down a little further then (carefully) pull the wires out of the downtube to get to the connectors. They're there, but may be a bit hidden.

Interestingly, the one designed for the 2019 Yamaha bikes does not appear to have the correct connector style (the Cross Core has a male 5-pin connector on the motor, whereas the 2019 SpeedUp box is made for the female 5-pin connector on the motor). So it seems like the Yamaha E-bikes are using...

Very curious if this will work for you. I also have a Yamaha-branded ebike.
