L-Twoo eRX Roadbike Groupset Review Install / Chinese Electronic Groupset Ltwoo eRX eR9

This video shares my experience of install & use L-Twoo eRX groupset. The Ltwoo eRX is a Chinese electric groupset for roadbikes. I try their eR9 last year, and I did not like their front derailleur that much. This 2024 new version has improvements on the front derailleur.
This video also compare the new Ltwoo eRX group with Shimano 105 Di2 which I have been using for a long time.
Me English learner, I added a caption in the video, in case I pronounce some words wrong.
Thanks for watching.

great video, thanks, really appreciate the detail

[@jonathan_f2]

I just installed the ER9 groupset with the older front derailleur design. I made sure the chain was sized properly , added a chain catcher and enabled gear protection via the app. I found no chain drop issues using this method. In your video it almost looks like you could remove a chain link or two. Anyways for the price I think it’s great deal!

[@everythingRICHARDIFY]

How is your er9 performing so far brother?

[@edwarding4355]

That look so good.

[@ADVRaiderKTM]

Thanks for the review! Would love to see how the new Wheeltop EDX TX groupset compares to the updated Ltwoo

[@Clifu]

Sure, I will try it soon:)

[@IanCoveny]

If you’re thinking of L-Twoo, I cannot strongly enough recommend against it. I have two group sets, the RX and the GR9, and they’ve been a disaster. Unfortunately, I don’t have the platform that Trace/GC/Panda has, so L-Twoo just dgaf about my issues, and I’ve been stuck having to replace both with Shimano/SRAM. All-in, I’m out 2x what I would’ve been just going mainstream in the first place.

[@MyVideoHome2012]

If it struggles before shifting, it’s your height (distance) between FD and chain/chainring

[@Clifu]

Thanks for the tip 😁

[@mitchelodebei]

Hello, congratulations on the video! Could you tell me the average battery life?

[@mateuszkochanowski6018]

Hi, have someone simillar problem. When move at FD from 1 to 2 sometimes all system go off. To wake it up i need to plug charger.

[@LeenksBarrow]

Can u link shop where you bought ltwoo on ali ?

[@2ninjamoz]

where did you buy it? i find only egr. did you try if new fd works with old erx?

[@testdirver]

those l-twoo caliper would fit in a post mount frame without any adapter?

[@jasonstanley9857]

Can you share which Aliexpress store you purchased from.... Thanks

[@djmanahan9466]

How about the brakepads? Can i use shimano? Congrats! Very nice video

[@joehiatt1992]

yeh 1st..anyways I just installed a Er9 & Erx on 2 of my bikes(merckx & Emonda),dialed it all in ,so far these grops are awesome for the money,I hope LTwoo come out with a rim brake version as I have 8 roadbikes with rim brakes,I didnt get the updated versions as u did

[@Clifu]

"Wheeltop EDS" has came out a rim brake electronic groupset not long ago, I will try to get one to play with.

[@ravurmovie]

I heard that the new eRX 2.0 electric groupset will be released in June. Can you confirm this? I do like the new color branding more, it has a blue color to it.

[@endtimeslips4660]

i run this ltwoo electronic before the old version. but i sold it to someone. my biggest issue with the old version is chain drop when shifting to small front chainring. wonder to see how good this new version hope seen your review after ride this thing for more miles.

[@Clifu]

I have same problem with the old version too. The new version is so far so good, will keep using it to observe.

[@MyVideoHome2012]

I have the original version. The chain drop is due to your limit configuration. I had a chain drop on my first ride. Realised that it’s further out than what I originally set to, so instead of aligning for the chainring, I adjust the limits and it has not drop since. Running HardCvr crankset (11S) from Aliexpress. 12S HG lightweight cassette + 12 speed chain

[@everythingRICHARDIFY]

How do you think this one is compared to wheeltop eds tx?

[@touzenjodan]

I believe that if you purchase such devices from overseas, there will be legal problems with radio waves, but are the regulations in each country lax?

[@Clifu]

Yes, I know what you mean, some countries do. I am from Taiwan, in Taiwan we have this regulation too, but if it is for personal use, and the quantity is ONE, then it is OK. When I order anything with radio wave oversea when I was in Taiwan, like bluetooth keyboard or bluetooth mouse, the post office always want me to sign a paper say that is for personal use. But in USA, the post office never bother to do it, I guess USA do not have this rule.

[@MyVideoHome2012]

This is using BLE , if these is legal issues with this, then every laptop and wireless mouse that goes through the airport every hr will be stuck .

[@nguyenanghoaian8667]

Is L-twoo contact with you to test their product?

[@K3vz2023]

Does anyone know what ospw compatible with old er9

[@mateuszkochanowski6018]

Do you know if shimano disc brakes will work with this group? At current bike I have 105 disc brakes and will be grate if i could swap only derauliers

[@mateuszkochanowski6018]

Tested yesterday, not pass :/

[@justineseiferth8010]

I've swapped out 7070 calipers and they worked fine.

[@michaelbruceharding]

do you know if there is a compatible oversized pulley wheel for the eRX rear derailier?

[@justineseiferth8010]

Stone and other 15t pulleys work fine. Just make sure there's room for the lower cage.

[@nameaze]

Can you give me a link of the product? Can't find the new version

[@Clifu]

I think it is not yet released in Aliexpress, but will soon.

[@nameaze]

Oh, I see

[@pawelodz8050]

Does it have auto trimming? If not, no group for me👎
