LTWOO ER9 & ERX - Electronic groepsets

[Unknownftp]

Didnt see it in other pages but if it was already covered apologies.

ERX V1
But my batteries died so I left it to charge for a bit, cleaned the charging port and cable with alcohol and it didnt charge at first. Finally got it to charge but now the rd indicator light flashes green rapidly and will sometimes shift. It also is not going into sleep mode either. So after the battery ran down this time I charged it all the way and now the light is staying solid green without turning off. Looking in the app, the system thinks its still charging even when the cable is disconnected entirely.

Anyone know how to full reset the RD or encountered this before? If the rd is braindead, I'm not super sad as I've gotten about 2k+ miles outta it, plenty of wet rides and all, but would like to at least try to get it worked out.

-Update-
Green light is no longer solid green but doing the slow blink green it does when the charger is connected, again when it is not connected.

Today first outing in the rain, so far everything is ok... let's hope

Does V3 use different batteries?  I have seen two different battery requirements for V3.  Anyone know anything?

The ER7 seems to have benefited from all the improvements of the V3 ER9/X especially the improved water sealing. Also having spent sometime reading about the complaints people have with Wheeltop EDS TX/GeX, LTwoo seems to have ironed out most of the problems with the groupset.

everything i have read says the holder is the same but you have to make sure to get 14500's with a button top

Hello everyone, since batteries are sensitive to the cold, and I live in Italy's, Aosta Valley, where temperatures drop to -10°C in winter, do you think it's better to remove the battery and bring it indoors at home? If you leave the battery disconnected for a long time, will the parameters be reset, or are they saved to an EEPROM and remain saved?

Depends. Do you store your bikes in an outdoor shed/garage? Some people have had issues with cold weather, but it's mainly due to shift buttons getting sticky. I haven't heard anything in regards to batteries.

Hi and thanks for the reply. I leave my bikes in the garage, but it's unheated, and it's a single garage, facing the house, so it only gets a little heat from sun during the day. When the temperature, perhaps if it's snowed, is -10°C out, the garage could be around -2°C.
I had this doubt because a friend of mine had a dead e-bike battery after a winter, and the mechanic told him it was because he'd left it out in the cold all winter without ever charging it (but I don't know if that's true).

I've found a "possible" bug with the Bryton Rider 460 cycle computer. When I start ride, but only when I start for the first time, I get a low battery message, but when I check the battery status on the Bryton it says it's full. Then the message doesn't appear again until the start of the next ride. Has anyone noticed the same behavior?

I'd just leave the batteries and check periodically via the app if there's drain from the cold weather. I didn't ride my bike for about 3 weeks and it was at 87% from full charge (stored indoors). It only took a few minutes to charge back to full.

Any off-the-shelf hydraulic cable and BH59 barb+olive will be fine.

I have an erx v3 which I had read used bh59. I presume the hose and olives are the same but the barb has changed. It now has a rubber o ring build into the barb bead. I have a small kink in my front hose, I'd rather replace, but I can't find this new barb anywhere. Anyone have and source for this? Or experience just using a regular bh59 olive? I don't want to destroy a lever or caliper putting the wrong barb in?

I bought from this, but I see is no longer available.

I actually saw you put that link in a different post. Keep hold of them!! They're a rare commodity now!
Do you know much about brake hoses? I don't know what would happen if I just used a standard bh59.
That link has a part number HW0249.
If you Google that it just brings up the regular set, without an o ring seal?

I'm not very familiar with this yet, I'm just learning
But I asked the store on Aliexpress where I bought the Ltwoo groupset, and they sent me a link to something that looks like the BH59.
In the meantime, I found those Ltwoo fittings with the O-ring available, so I bought 4 sets right away becouse with this o ring it looks "safer" for me.

Just rewatched a trace velo video on the erx 3.0. He has a bike with the erx 2.0, and swaps out the shifters and derailleurs. He leaves the old barb, and olive which I probably wouldn't do, in the hose and puts it straight into the new shifter. Maybe it doesn't matter at all!
