Hello, I have the same bike as you, and I replaced the 9/46 cassette with a 10/48 garbaruk, (forced to replace the gear cage with a garbaruk cage) for 1 year and 4000 km everything is fine. gears still shift as well and silently. If you go to 10/46, no need to replace the gear cage. I replaced...
remove the protection under the motor held by 4 screws, 2 in front and 2 behind, be careful to hold the motor, so as not to break the battery connector when falling.
the problem is due to the value of the wheel circumference set in the decoy, Yt set a value of 2300 mm which is the circumference value of a wheel of 29 ", you have to set the correct value for a wheel of 27 , 5 "which is 2180 mm and you will have a correct speed limit
have you correctly adjusted the wheel circumference, mine arrived with a circumference of 29 "when you have to adjust to 27.5" and that could explain the speed shift you have
it works like that, except for the trail mode which would not be linear dixit shimano, I have doubts and the eco mode which is adjustable like the others
eco: 40/70 trail: 70/70 boost: 120/70, my outings are on average 40km and 700d + at 15km / h on average and I have 50% of battery on average on arrival.
ok, but in one case we have the ANT private protocol and in the other the bluetooth, those are two different channels? so you can't use the smartphone with the garmin at the same time, it's less interesting for me.
