I have a Forerunner 255, works great for E-MTB and all the other Acitivits
The price is really good

I have a Garmin 645 Music and am unable to connect to my Trek Powerfly (Bosch motor).

I will caution about one thing, however: I have two Bontrager lamps with Bluetooth functionality. One day my Garmin, without me doing anything, connected to these two lamps (front and rear). Since that day every time my Garmin connects to the two lamps, a "network forming" message appears on it and... the lamps light up.

It happened that the flashing red light came on at night waking me up as if there was a SWAT operation going on in my house , but what is worse: the lamps discharge. Apparently--I searched the internet for a long time--there is no way to fix the problem on the Garmin, due to a software bug. And the lamps are not resettable. The only solution I have found is to store them in a metal box when at home.

That said, I would also love to be able to see the data on the watch but unfortunately I have not found a way. One would need to understand what the communication protocol is, which unfortunately is proprietary. In fact the only Android app that is able to do this with my ebike is the AWFULL Ebike Connect, which is full of bugs and impossible to control.
