LTWOO ER9 & ERX - Electronic groepsets

[jonathanf2]

Have someone problem like me? Charging but in app not show this, show 0% of battery, on second fully charged.same situation. RD show thath battery is łów (2 Red light) and all not work :/ battery tested on second erx and work fine

Damn final solution RD is broken:/ change it with erx and all work fine:/ RD have 2 months

Wipe down the charging port with some alcohol. There could be some dirt interfering with the charging function. Also does your RD and FD function while it's plugged in? Try doing several hard resets while the charging plug is connected to the RD. Also try swapping out your FD and RD cables and see if that works. Unless you had some major water ingress, it could just be a battery issue or it needs a hard reset.

This is probably a dumb question, has anyone heard when the new ERX will actually become available?

Not a dumb question - it was first shown off more than 9 months ago and L-Twoo have been basically silent on it ever since.

I'm beginning to think LTwoo is lagging behind Wheeltop. Wheeltop seems to have better regional/warranty support and it appears OEMs are gravitating towards Wheeltop with fully assembled bikes. Not to mention they were able to acquire Rotor. I wonder if LTwoo's private equity is starting to dry up with no fresh funds? On one hand, I think only one Chinese groupset manufacturer will eventually come out on top. On the other hand, the inter-Chinese competition has forced lower prices.

well, wheeltop sponsored many full bike builts with a ready built price for 899 USD ....
We worked with ltwoo in order to establish the brand for being ready to equip oem bikes with the groupset....they messed up everything...we also have spoken to a couple of distributors who were basically turned down just by ghosting them, some visited the factory and came home frustrated..
So currently, i do see wheeltop ahead by miles..we need to see, how they work out the patent with flat mount brakes and other things which need to be settled to sell the product legally in EU regions....

Wheeltop has established a distribution network in the US with warranty service, so I'd presume the flat mount patent should be something they can deal with in Europe. Also I'm still not convinced with the fixed battery solution. Though Magene is the other big player coming into market, so it's not yet determined who'll come out on top. Though Shimano could probably lower prices for 105 Di2! Either way competition is good!

Fair point, the warranty and distributor network might help them a lot.

For Magene do we have any news on the groupset? Saw the video of Joe about it, but nothing more later on.

Asked them some weeks ago, Magene said the groupset is currently only available in China.

That is still strange. If it were (only) available in china, I would still expect to see or hear tell of it somewhere. Videos, photos, blogs, etc. Unless they're all exclusively on chinese media and website and haven't made it to any english media or websites, but still strange, I think. The only hits popping up on a google search are all from May or June of last year.

Not sure if this is related, but I was emailing Magene last week regarding their powermeter and they mentioned that a new version of PES P505 and their powermeter pedals will be released in May. Perhaps they intend to release it together?

This was posted on the forum here back in November when it was launched:

May would coincide with the China Cycle show so I'd expect they intend to show them off there.

cycling media is clueless about equipment in general, all most of them are good for is regurgitating the talking points of marketing departments

Has anyone swapped out their 12t/11t jockey wheels for Ultegra 11t/11t wheels on their ER9? I'm running one of my ER9 setups with 50-34/11-34t and I've been getting chain drops with this setup on 50km/30mph plus bumpy downhills. On my other ER9 52-36/11-32t setup, this isn't an issue. I'm guessing this is why 11-32t is the official in-spec max cassette size. I wanted to see if going down to 11t on the lower jockey wheel might help mitigate the chain drop issue by allowing me to move the cage closer to the cassette. I'll report back if this might help.

BTW - I'm staying with the ER9 reversed lower/upper jockey wheel configuration (compared to Shimano). I'm not sure why LTwoo does it this way. Even the EGR has this configuration, but it seems to shift fine.

Guys, running ERX for 4 month now, so far working but with annoying message from Garmin everytime that the shifter battery is low.
I run into issues with wet weather and cold temperatures. Battery died quickly, although the App/Derailleur shows that the battery is fully charged.

It seems that using the App leads to incorrect charging, so do not try to read the battery status with the App. Just plug the cable into the RD and let it charge.
