Thx for your advice.
Yes for me it’s the connector in the frame the problem.
He is Broke.
Canyon send another one, and after I hope everything works.
I can talk with Canyon France, they advise to me, to not Unplug battery for have less problems.
Well, after 80km, I am among the unfortunate owners of a Strive with battery issues.
I took the battery out today to charge it, and since then, I can't start the bike; the LEDs light up and then go out. However, the battery doesn't seem to have any play, and nothing appears damaged.
For those...
