Lightcarbon carbon fiber EMTB frame with DJI Drive Unit

I's definitely confirmed the Teewing is made by LC and these two frames are one in the same despite Teewing trying to deny it; a guy in the Teewing thread just got his LC frame in the mail this weekend and it's obviously the Teeewing bike based on appearance, and it even has Teewing branded hardware for the shock mount.

That would be me. Its the same. As far as anyone could try to claim at least. All the hardware actually has Teewing labels including the headset, and the frame would have too if I didnt ask not to have it (which I probably shouldn't have, but there were not reviews in the wild at the time). It was ~3500 shipped to the US. Ordered in August.

Great report, thanks. Mine ordered similarly. For those doing the own painting, about how hard would it be to disassemble the frame 'as delivered' to componet parts for sanding, etc.
Beautiful bike!!!

We have noticed some recent misunderstandings regarding the manufacturing source of the Teewing frames. We would like to clarify that our frames are independently designed by our team and manufactured by the largest carbon fiber factory in China, which also produces frames for many well-known bicycle brands. Our frames are definitely not manufactured by LC.
We met LC at this year’s European Bike Show. We provided them with six framesets, and they said they would recommend them to their clients in the US. However, we discovered that LC stripped the paint and repainted our frames, removing our logos. This was not permitted, and we have since ceased our cooperation with LC. They will not be receiving any more frames from us.

Trivial I'd say, just undo the bolts and run with it. Just note the lower shock mount is an area of quite tight tolerances. I had to sand it down due to overspray even from LC (about 0.4mm off by my measurement).

I'm really not sure thats the hole you want to be digging here... time would show quite quickly if 6 or more framesets + motors ship out.

This isn't a Pinkbike forum...

Anyways, for people like us here that detail doesn't really matter end of the day. The frame looks like a product winner and the sooner you can offer it direct in the US the better. As I said in the other thread, I'd strongly recommend considering offering a "racing" style version of this same bike, using the general finishing kit that you have on Théo Charmes bike. It is true that the 150/145 stock configuration would probably be your highest volume, but there is still quite a good market for faster/lighter builds (around the 130/140mm range) particularly since you could advertise class 3 installations that DJI has enabled for the motor in the US (at a candence you could actually pedal). The new shimano xt 9-45 would make a wonderful application for that, but if you insisted on staying sram, even pushing the 36:10 limit they offer would be a big step up from many other emtbs on the market up until now.
 
What a weird saga, I knew something was going on based on the answers from some (Teewing) and lack of answers by others (LC).

In any case, the bike seems great and if LC is making the frame there’s nothing to hide there, people would feel much more comfortable knowing it’s them than some unknown factory.
 
So, maybe we know now why LC had cancelled the order...
Yeah... I can't imagine they actually switched frame suppliers that fast, but I bet they lambasted LC for selling any frames direct and mentioning it was the Teewing frame and put them under some NDA to mention the Teewing name at all or disclose that they're making anything for them. Which sucks, but I get it, if I was Teewing I wouldn't want the frame manufacturer selling frames direct as well, especially without the logo if they actually did do the design and just asked LC to manufacture it. Now if LC designed the whole thing and Teewing just decided to buy them in bulk I would feel differently.

Their story makes no sense whatsoever. They’re implying LC took a handful of free frames they were given and went through all the trouble to strip the paint and resell them just to make a few bucks on freebie frames?? Give me a break 😂 And if they already had frames made somehow, why would they need to be giving them to LC??? Bizarre story. The lies some of these guys tell are wild.

If the frame was $3500 shipped to the US, what duty were you charged to get it to your door? Frames from China have 3 import duty hits: standard harmonized tariff duty + Section 301 Trade Act + Cheeto's Reciprocal Tariff. Currently this is like a 55% duty.

That was duties included. I cant say it will be the same when you do it now, since the rules seem to be changing by the day.
 
Shes complete and I've been out for about 10mi. Downstroked front and rear, most supple bike I've yet ridden. XT Di2 Buildset, used a 150 dropper (should have done a 175 or 200 but I didn't expect I would end up as high up as I did). 203 front brake, 180 rear (just easier for me to find one that played well with 6 bolt adapter, not trying to save weight).

I'm a weirdo with long torso, short arms and legs for my height so Jones bar it is. All told despite the super heavy handlebar... the bike weighs 45lbs flat with pedals on. Not too shabby.

Also surprisingly... wife approved. Wife very much approved of the look.

As of a few years ago, there was a weird wrinkle in Chinese trade rules, where a manufacturer of goods could not also be the exporter. In other words, someone who wanted to have a vertically integrated company was required to separate manufacturing and distribution/export into 2 separate companies. As a result, you could get situations where an export company like Light Bicycle is selling rims, and talking about "their factory" and, for most intents and purposes, it is "their factory", but it will be called something different like "XYZ Industrial" on paper. Even though they share ownership, they're not technically the same company.

Then if you have a 3rd party brand that is white labeling the same rims from the manufacturing company, and a consumer asks "aren't these just re-labeled Light Bicycle rims" the 3rd party could claim that they weren't made by "Light Bicycle", which is technically true. At the same time, Light Bicycle could claim that they were selling the same rims as the 3rd party company, but for a much lower price, which would also be technically true, leading to a lot of confusion in the consumers trying to verify the quality and origin of the products. That weird corporate structuring lead to a lot of misunderstandings, but also deliberate manipulation/misrepresentation by marketers. In addition, there could be another variation where the 3rd party has asked for something like a small modification to the white labeled rims, to allow for thicker sidewalls, or a mostly cosmetic change to the shaping, or something, and has agreed to pay for new molds to allow it (which the 3rd party will now own), so their rims could then cease to be identical to the Light Bicycle ones, even though they are still very similar and coming out of the same factory. If they really want to stretch the truth, the 3rd party might even claim to have their own manufacturer, when really what they mean is their own molds.

Bringing the conversation full circle, based on my reading of the claims made here, it seems possible that LC has a similar sort of parent/sister company that is who officially does the manufacturing, whereas LC does retail-level exports. Teewing may have designed the bikes themselves or had them designed by a specialist (I saw the claim that the design was done by a European based bike design consultant, not sure if it's true) and had them manufactuered by LC's parent/sister company. Then, given that Teewing didn't have great distribution in some global regions, they may have considered sharing their frames with their manufacturer's sister company (LC) in exchange for some sort of compensation, as otherwise they would have no access to the consumers in those markets. Clearly, it doesn't seem to have gone well though, leading to the very mixed messages we've been getting on here. A lot of this could be cleared up if anyone was willing to specify who did the design, who owns the molds, and what is the name of the actual manufacturer of the frames.

I agree 100% that the story about a high-volume seller like LC stripping the paint off 6 frames to try to make a quick buck doesn't make any sense. But if LC thought that there would be a lot more frames available to them, if there was sufficient demand, I could see them stripping some to have a few samples to show around.

Afaik, no one else has confirmed receipt of a paint stripped frames besides me, and that was only on my specific request, so I wouldn't worry too much about the specific # statement. I feel like my contact would have mentioned if they had limited stock.

The picture I saw from the factory with 2 other frames (of different sizes) in an UD state.

Of course even there, your insight on the arrangments sounds way more likely than anything we've heard here direct from them. It isnt like I paid a company explicitly named "light carbon" the invoice anyways...

As far as the design goes... I mean this in the nicest way, but it really just seems like they took the Trek eXe and did the mods required to fit the avinox motor. Which I'm 100% on board for tbh, but still. Screenshot_20250929_091101_Chrome.jpg

Yeah, I'm with you 100% in regard to that a bike doesn't need to be designed from scratch, using a totally revolutionary design, to be good. I often wonder, when there is a bike that is universally acclaimed, WTF the manufacturer is thinking when they do a total overhaul/change of design on the next revision, rather than a few subtle tweaks. Similarly, I often wonder why more companies don't copy a "known good" bike, perhaps with some improvements if they have some good ideas and insight, but this constant starting from scratch seems to leave a lot of companies in a tough financial situation with unsold inventory, and it leaves a lot of riders with crap kinematics, geo, or hardware design, when this stuff should be pretty well figured out by now. Regarding the location of the Teewing design team, our discussion prompted me to do some really deep digging ;)(their own website!) and I found this, which must be the source of what I'd heard about the Euro design team: About Us
 
Everybody speak like if light carbon is a "major" frame builder who produce for several "biggest" bike brand ? I have an different opinion and i still waiting the facts who prove of these resumption of the alone marketing speech of this company.

Thanks for the deep dive, going to the "about us" part of a website marketing section as per the "wink" emoji

I believe that the design is right in the hunt for what will be relatively "state of the art" currently and in the near future. However, speaking of their claims on the "about us", I have a few items below that could use some clarification: (Warning, long post ahead :) but I wanted to give full context)

Claim: “With over 15 years of research and development experience serving high-end bicycle brands”

Reality check:
Teewing as a brand appears to have launched around 2023 (their own website says this).

There’s no public record of a company called Teewing operating before that under another name in the bicycle industry.

Therefore, the “15 years” almost certainly refers not to the company, but to individual engineers or their manufacturing partner(s) having experience working on OEM/ODM contracts for other brands.

Possible truth:
Some of their staff or partner factory engineers probably did do contract manufacturing or R&D for other known bike brands for many years (common in China, Taiwan, or Italy). But:Frami ng this as “our team has 15 years of R&D experience serving high-end brands” is ambiguous marketing language — technically plausible, but not evidence of Teewing itself having 15 years of history. It’s a credibility inflation tactic.
Claim: “Leveraging strategic partnerships with one of the world’s top ten manufacturing factories”

Reality check:
“Top ten” has no objective ranking body — it’s a marketing superlative, not a verified fact.

They don’t name the factory. That’s a red flag if you’re looking for transparency.

Many new e-bike startups use this kind of phrasing to sound established (“we partner with one of the top OEMs”), when in fact they might just be sourcing from a competent but generic large-scale Chinese OEM.

Verdict: Fluffy marketing phrase — no verifiable metric behind “top ten manufacturing factories.”

Claim: “Our journey is bolstered by a strong collaboration with our trusted Italian partners … to ensure they meet the rigorous demands of the European market.”

Reality check:
They do have Italian riders and possibly design collaborators (the Teewing Factory Team includes Italian racers and references an Italian design office).

However, this could mean simply that some product testing or design input happens in Italy, while production is still done in Asia.

Possible truth:
They probably have Italian consultants and testers helping tune geometry and handling.

But:
The phrasing “strong collaboration with our trusted Italian partners” and “meticulous attention to detail of our Italian technical team” is classic brand storytelling — designed to make the product feel “European-engineered,” even if the bulk of R&D is elsewhere.
Claim: “Every product undergoes extreme trials to guarantee performance under the most challenging conditions.”

Reality check:

There’s no publicly available data (test protocols, lab certifications, ISO/EN test reports) to substantiate that.

“Extreme trials” and “guarantee performance” are narrative phrases, not measurable claims.

Verdict: 100% marketing copy, not engineering documentation.

Yeah, I agree fully. I was even zooming in on the pics of their Italian team as there is a lot of data on the monitors in the pics, and I was hoping to glean something valuable, but the resolution wasn't sufficient to make anything out. Maybe some sort of image-enhancing and detail-sharpening program could make it legible, but that was as much time as I was willing to invest.

And nothing I've said should be misconstrued to mean the bikes aren't good. They genuinely look pretty sweet to me, which is why I'd engaged with this thread initially. Its just an example of a marketing department run amok, targeting newbs, and forgetting to take into account the serious geeks like us.

I’m sure like you said, they had 3 guys on the team that helped with the design each with 5 years experience in the industry and concluded they could market the phrase “15 years experience”, one of my old employers did that to come up with some ludicrous number for their experience.

But it does seem like a well thought out bike and as long as the carbon is of good quality should do very well out there provided they survive as a company and provide good support.
 
Any chance Light Carbon will also have an enduro frame with the DJI motor coming out?
View attachment 171909
I saw someone mention they had a burlier bike coming but didn’t know anything had been leaked yet. Is there a source of that pic with more info or is just a leaked image? Looks so much better with the Teewing logo more subdued.
 
Photo is from the Facebook Teewing group. 170/170 high pivot. Apparently not out till mid next year when the DJI motor update comes out.
