Hindsight is always 20/20.
I tried the shimano e-tube app and not get anything to connect when the bike was on.
Visually the display cable did not looked damaged, and both connections points were clean and secure, so I did not try the cable right away because I assumed it would be fine. Also...
Thumb switch one is short. Speed sensor is med. Display is long. I’d buy a long spare one, and it will work plenty fine for the other two. Just loop it and secure with some electrical tape or a small zip tie.
On the bright side I have become extremely good at working on the internals of this e-bike. Time to go ride a bike I know won’t have electrical issues while I wait for my parts.
Found the culprit. Swapped on my friends shimano di2 cable that connects the display and everything is up and running again. Just to verify, I tried my cable on his bike and he also got the black screen of death. Should be able to find one online and have my bike back together by mid week.
I...
Update:
swapped displays, swapped batteries, swapped full motors. My bike will not turn on still. While I have it off I may try my parts on his bike just to verify before I start ripping out all the cables.
I absolutely hate how there is no room to plug in these connections due to the frame overlapping the motor. Two other bikes I’ve seen with shimano motors have a plastic cover that removes so you can actually work on your bike.
pro tip: to be able to do this with the least cussing possible...
Without a Bluetooth connection, I do not think it is possible to connect to the shimano app. To be fair I did not try, but assumed if the display is off, the Bluetooth is also off. Will try again once I get the bike back together.
No light being used on my bike.
yes, connections are clean and...
I’m hoping the new motor will be quieter. Other than the noise, I enjoy all the other aspects of the shimano motor. (Oh, also if it could work all the time that’d be cool. Mine is currently sitting in a box in my garage. But haven’t had a chance to diagnose the problem yet, so who knows.)
What...
Took everything apart and could not detect any source of error. My friend also has a decoy 29 so hopefully I can borrow his and swap parts out 1 at a time to figure out what is wrong. Hoping the display cable went bad or something, but we shall see. Thank god I have a normal (2020 Enduro) bike...
Today I tried to ride my decoy and it wouldn’t get out of the parking lot. Rode it a few days ago and everything seemed normal. Charged up normal. When I turned it on before my ride everything booted up normal. Then as soon as I was switching it into eco mode to take off, the screen went black...
I think I could get around $4000 for my bike after 2 months of use and even after I put most the stock/cheap parts back on.
I’ve sold 3 bikes in the last few months and they’ve all sold way over what I thought they should have.
I don’t think buying a new rear end, wheel, and shock is a cost effective option.
At this point, I’m either going to stick with what I’ve got for a while and not invest much more money into it since I don’t see it as a long term option. Or sell now while it’s still “newish” and the market in...
