- I built a cheap full carbon fibre electric mountain bike and in this video I show you how! Link to Build and parts: bit.ly/3OMuaEg
Chinese Carbon Frame, Dengfu E10
Bafang M510 Motor
840Wh Battery
Geometry:
Size: XL
Head Angle: 64.5 Degrees
Reach: 510mm
Chain Stay 459mm
BB Height: 356mm
Could use offset bushings to reduce the BB height and make it slacker if needed!

This new M510 motor is really strong! Looking forward to sharing the next video! ps - this is a new frame, not the same one I did before. DENGFU revised the frame slightly (new charging port location and new battery cover that is quick release. Looks similar as they painted it THE EXACT same colours from my last video! Also, motor is the 2022 Bafang M510).
I was confused at first, thinking it was the old bike. Now I really want to build one!
Thats 23.98kg with a 840wh battery!! That is lighter than my old carbon trek Powerfly which only had a 500wh battery. You might be able to put a smaller 400wh battery and get down to a sub 20kg bike with a few other mods.
Will the frame withstand a actual mountain biking abuse? Not jumping but the bumps and what not. Great video
Hello Rob Rides Emtb , we sell the same bikes - MAX CARBON here and we also use 550wh 52V custom batteries, which is almost 1kg lighter , which will bring your bike down to 23kg. VOLITION EBIKE Australia
Honest question: If you order a Shimano drivetrain from Aliexpress, how can you be sure that it is not a fake Shimano drivetrain?
Interesting build btw!
In this day and age of £12k+ bikes I find builds like this really refreshing. Especially as this is a much more affordable price range for me and makes the prospect of owning an E-MTB more likely! I'm looking forward to seeing your video of it being ridden.
you get what you pay for
@@MOAB-UT which 1/2 the time is labour (see what I did there? ;) ).
@@MOAB-UT Nah, not in the world of ebikes, all share the same basic CHINESE electrics then charge you for the NAME on the sticker.
@@ianmangham4570 This is mostly true actually.
@@marksimpson4005 No.
Loved the CHEEB. So glad you went for V2. This has to be one of your most popular videos. I only wish you had full parts list and an extended build video so an idiot like me can build by numbers 😂
Nice.
You don't even need a headset bearing press. If you freeze the bearing cups. And use a gentle amount of heat from a heat gun or hair dryer on the frame. Then the differing thermal expansion rates let the bearing cups slip right into the frame.
I did it exactly like that on my dengfu e22 (basically an e10 with a bigger motor).
I thought I was the only one who had worked that trick, back in 1986 with my ducati.
Now that is a neat trick! 👍
yep, I remember my LBS getting angry at me for freezing the cups as they had no idea how i got them in haha
Kudos to you Rob for showing us the Dengfu / Bafang combo again. You could have stuck with the major brands and milked it. Well done mate. Super keen for the next video.
Best Part About this Bike is the quality choice of real mountain bike parts and components. Not only that but you smartly choose high quality parts at good prices. Most pre-built Bafang Powered bikes out there are running a junk spec on drivetrain, brakes, wheels and tires. Well Done, I would love to see follow up reviewing this motor vs. other Bafang Motors like the BBSHD, Bafang Ultra, etc.
Just wanted to let you know that you inspired me to do my own build like this. Unfortunately dangfu didn’t have a xl frame other wise it would be a totally similar build. I was able to find another company and just finished. Thanks for the inspiration. By the way I named it CDIY.
I've got a Dengfu E22/Bafang M620 build from a company here in the US, love seeing more of this stuff!
E22 looks interesting too!
Can you recommend the company/seller? Looking for the same
I just finished my e22 build. I am wrapped with the performance. It's a kick arse bike without the killer price tag. And the bafang ultra is a beast
Kyle White, can you post a link to where you bought your bike?
@@tonyrobinson1623
Perhaps Luna or WattWagon???
great video nothing more satisfying than building your own bike.cant wait for the ride review
Same colour as the swordfish TVR! Love it!
I've had mine since Rob did his original Cheeb build.
I love it. With 150mm fr & rr and the more powerful M600 motor, it's a beast that I highly recommend 🤙
What happened to the ride video on this?
This seems like the perfect solution for me! I would only need the frame, electronics and suspension. I could just take the rest from my polygon T7 and complete the bike! Easily under $3k, maybe even $2500 if I find good deals on the suspension!
Helpful video - figured I need to build my own commuter e-bike to get what I want - a decent but not necessarily very powerful mid-drive motor, large battery, Rohlhoff E14 belt-driven hub, large enough ring to cog ratio to be able to reach 30 mph at maintainable cadence.
...and all this should be in a full suspension frame with 29" wheels and hydraulic brakes...
I bought both my motorcycles for $3500 each and they will just last so much longer, better, faster, etc. that was back in 2006 when i realized there was no comparison, even till this day. but I love this video and how far technology has come!
I got one E-ten with the M600 and Formula Selva C for the front, I tell you it is a beast. Amazing bike, compare to what others brands do and price wise...clearly Dengfu is a pearl you need to think of when you move to e-mtb.
Im tempted to build one after seeing this… well done on the super build !!
Good job showing an alternative way to get a eBike. Not so fast on the most powerful eBike......I have one of the original Bafang motors that outputs 160Nm of Torque. My battery is 52 volt 1100Ah....all put in an Luna Cycle Apollo...I love the bike for all it can do.
This was absolutely incredible and super inspiring! After watching this I certainly want to build my own e-bike. However, I want a road bike, not a mountain bike. Thanks a million for this!
You can definitely build an electric road bike, you may want to split the difference and do an E-gravel though because the extra motor/battery weight can feel ROUGH with no suspension in my experience
@@tamholt3494 Thanks! I'll keep that in mind. Keep on rocking!
@@tamholt3494 Thinking about what you said, how about a bike without suspension, but with gravel tires and a seat post with suspension?
That's why I love Chinese products. Nowadays, they produce cars, especially EVs and other electrical gadgets and products of European quality but at a much lower price. Not all of us can afford to buy American or European-made products so kudos to the Chinese and other Far Eastern countries.
Yes Chinese products have really come a long way. Now they are almost at par with the world in terms of quality at a much lower cost.
This is great! But, come on Rob. Where's the test ride vid? I'm really interested to see what you think of the M510.
i built my Alloy version and now am building the M600 version in carbon. Carbon components where i can as well. Wheels are carbon, bars are carbon and so on. I have the Bafang motor controller programming kit and will update the amperage output as well. they run 18amp but the controller can safely go to 25amp. i will run 22amp and although i have the standard battery (840 watt) i will also build a custom battery as i did with my other bike. I have access through my work with a company in Japan to Sodium ion battery cells and aluminium graphine batteries. Using a conbination of both cells in one battery unit (requires 2 chargers sadly), i get over 1000 watts and the delivery is so good, that after 759 cycles on my current bike the battery still reports 99.97%. The drain I suspect is not the battery, but the degradation of the wiring between cells. Therefore my next battery with run a silicon wire we use in satellites. With my bikes i dissasemble the motors and seal the controller board with Urethane conformal sealant, and the joiners all have electrical greas on them. We also shrink seal any joins. the battery compartment is sealed as well and the bike has no issues if submerged. I am so excited with my carbon version.
this is amazing!! I have no excuse not to build one!!
Really like this vid. Fired me up to build my own E-Bike.
Thanks Rob.
Everything but bare cables where the slap against the hollow frameset would drive me bonkers ! 👊🏻👍💪
A lot of people overlook Deore, but those 4-piston brakes are really, really good.
That bike looks Sick AF but still out of my range i bought car for 4k euros so this is just a dream ;)
Press headset with long bolt / nut and big washers
thats exactly what i do too
When are you going to drop an update video for this build (and motor specifically)? I think a lot of us are very curious of the differences. Also curious on your thoughts of building a bike like this versus buying an similarly priced entry level spec bike from a dealer with a good support network (Ex. Orbea Rise H30). Keep up the good content.
I love the idea of this bike. However, I am wary of the way I would have to go about contacting and then paying for the frame.
Also I would love to have some specs on the frame. Headtube angle and bearing sizes, Seatpost angles and size. Rear shock dimensions..etc...
As always Rob, You've done well with your build 👍🏿
You caught me off guard with the weight of your xl E10. Mine with the M510 is around 24.4kg.
Anywho, keep up the great vids dude. I'm always watching 👍🏿
My 1st tip, aluminum frame. 2nd tip, Bafang Ultra
If it doesn't crack/snap, it looks really good actually! Nice vid.
@@BradCagle Not a surprise, but still sucks.
This exact Dengfu E10 frame? This would be the first one, there are many out there and not a single report of one has cracked.
Are you 100% sure it’s Dengfu? Please check, as I’ve not seen any Dengfu frames crack so far.
Once again great work Rob .. I built one up after your original videos with an M600 .. awesome bike!!
That thing looks awesome. Great job and inspiring stuff.
Awesome 👌 Thanks for a stunning ebike build pro demonstration. Looking forward to your test review of this ebike 👍😁
Thanks for the inspiration! I'm seriously thinking about rebuilding my hardtail carbon framed bike to a ebike with a befang kit, but it's scare when you have no idea of what you are doing, hehe
Excellent video, and thanks for teaching folk how to do this, have you considered building a 2 wheel drive bike, there is no comparison off road, I first built one of these about 12 years ago, using 2 heinzman hub motors, mounting half the power pack on each side of substantial forks allows the machine traction when in 5 feet of fast flowing water. furthermore mixing up a geared low torque and gearless high torque or vice versa, also adds some interesting performance characteristics, my first one had a half million candle power spot light, and if you didn't use a key to start it, it would hit you with 72 volts to deter theft, the last 2 parts are probably illegal now and qualify as weapons, but it would be nice to see you make something that did 0-60mph in 3 seconds or so.
Looks better than most hope you do a long term test
Fun to watch you build this one!
Liked your comment “like LEGO”
super clean looking light full suspension ebike. the frame looks weak around the pivot point for the rear chainstay, tho. I’ve never rode a carbon frame, admittedly, so maybe my worries are mute.
Great stuff! Looking forward to more content about this build
Did you ever post a ride review. I couldn’t find one
What a mint looking bike, looking forward to your next video Rob.👌🏻
Impressive build Rob, well done 👏🏼
Great job on engineering & developing such a great usable product looking forward to changing my ENG PRO 2 when you restock your supply.
My carbone frame with fork was 1500 2014 GT BMX.
Just a quick FYI, the Nukeproof mega chainstay protector fits the e10 perfectly..
Great to know!
Which chainstay Alloy? Carbon? Model? Thanks!
@@iouzip2055 alloy
The Cheeb lives ! Long live the C H E E B ! ! !
Great video, great bike - your DENG FU is strong ...
Nicely done Rob came up looking super nice i had a bike that exact colour in the 90 s watch out for the industry giants hitt men ha ha the margins on big bike companies stuff is totally insaine i,m an ex industry insider who wouldnt lie trust me the margins are unbelievable no matter what they tell you .
Looking forward to the test ride, you have really got me thinking now.
Is there going to be a follow-up to this video? Would love to see one!
Hi Rob love these videos when are we going to see the full test review ?
Yet another great e bike build 👌🏾. Beautiful ✌🏾
Really enjoyed this video. Was thinking of assembling a new bike myself. Hoping to complete the components over time. Was hoping u could do a video on a build using the new integrated drives (motor and gearbox) and or systems like the Valeo, Olli or Reventon One paired with a carbon drive
Hi Rob , great project and a fantastically produced video. Much appreciated. You say this is an Dengfu E10 but I can’t see that frame available on their website and the other frames seemed to have seriously jumped up in price. There is an E04 currently selling for $879 but the E05 is $2,499 , E06 $2549 and E14 $2399!! How did you ever get that price for that frame?? Thanks again
probably reject pile + CF could be dangerous IMHO
I think the prices you referenced include the bafang Motor
you should make a video on how you take it on some real trails, that would be a true test cause the looks are fine, component are ok but durability would be the ultimate test.
look better than any iv seen is store
Have you made it up to the proper test ride video? I can not find it on your channel.
Rob! That build is AWESOME!!You just created a Beautiful EMTB And Thank you for using BAFANG as they are becoming very popular where I live and I know people who have insane kits that go 51mph off road although they are 72volt haha!!
What is the best source of information about the fast bikes you mention? I love my turbo levo, but building my own that is faster sounds like a great fun project!
@@tptrsn If you want to build something faster and more cost effective than what Rob built, check out JohnnyNerdout's channel. He builds Bafang BBSHD 29'ers. If you want to explore the margin of what the BBSHD can do with aftermarket controller, check out High Votage's channel. Or...you can follow Rob's blueprint if dual suspension and lower power motor suits your fancy of course.
@@lukewalker1051 Thank you so much! I will check out ALL of those things! I do love hitting some bike park jumps, but I also would love to play with something even more zippy. Seems like a lot of fun to be had with this stuff, and I've built a China sourced carbon hardtail before that was a really fun project. This seems like a "logical" next step. Lol
@@tptrsn If you want a quicker motor than Rob has used here, the Bafang M600 fits and has more power and top speed
I have this frame and motor combo and it's great, it's hit 49kph so far 🙂
@@Harddeckmyass Thanks for the tip!
This video makes me want to build one myself
When is the ride review coming out Rob?
I think I need one of these....
Number Two Rob………… How long before your producing your own Ebike brand? Your customers await you. 😀👍
I'M BLOWN AWAY
EAT YOUR HEART OUT YOU MAIN STREAMERS
Brilliant video Rob, thank you.
£3000 is not cheap!! You could have said cheaper which would have fit the video more!!
3 grand compared to 12 grand is cheap
For about $400 more you can get the luna cycles x2 if you do t feel like building one. Very similar.
Same bike, you can't buy the frame direct in the US as they are the distributer.
Can't wait to see more! I'm buying one of those, going straight to Aliexpress 👍🏼
Very nice! I have two Deng-Fu mountain bike frames with Bafang M600 motors. One has 3000 miles and the other 1200 miles. Both of them technical trail and gravel road riding. I think the M600 has more power than the M510? Also, I have 14S Samsung battery pack and 52 volt battery. Both bikes are Luna X1's. I tried to get a Deng-Fu frame and build one but Deng-Fu will not sell to US and Canada. Luna has an exclusive with Deng-Fu.
No big deal, I really like my Luna X1's. Thanks for the excellent build video
Oh heck yeah boy! Nice job. Great video, absolutly can't wait to see the ride video.
GUAUUU, Super Nice Emtb!!!
So excited for the ride review and performance testing of this bike! Any thoughts on when it might be out, or why it isn't?
Great question mate
Hi, this is second wicked video of assembling emtb electric bike, but! could you please make one of assembling eGravel bike? for some reason cannot find decent frame /parts
Really love your video quality!
Hello Rob Rides Emtb , we sell the same bikes - MAX CARBON here and we also use 550wh 52V custom batteries, which is almost 1kg lighter , which will bring your bike down to 23kg. VOLITION EBIKE Australia
you ship to the us?
you`re so excited - no plans to take it off any big drops then? I am tempted to do this in the future, but for now I still want to send stuff with confidence.
Does the motor have the 25kph limiter on it?
I just bought an used bike for 1000$ and installed tsdz2 motor with torque sensor, all for 1400$. New motor, new 750Wh battery, 3amps charger.
Great job Rob ! Do you have an online course or full end-to-end tutorial that explains the build of this bike or a similar e-bike ?
I’d like to see that also
Rob if you would do this again...What ebike engine would you buy? what options are available?
Thank you, great videos !
Wooo interesting very tempted to try this out for my self
Great vid, Rob! The Cheeb looks sweeeeet!
Super nice video Rob, I wish I had your skills to put together an e-bike....
Excellent video Rob of course , thank you .Rob when can we expect to see Test videos ?
Love to see the testdrive!
Those motors look smart but my worry would be what happens when it goes and needs warranty! Shipping costs and times there and back if you can get them to do it would be a nightmare.
If you need warranty, will you need to send it to china or to poland? Because bafang has a production line in poland, i could image, that they will also take care about warranty cases from europe, not sure about usa/australia
What a cool and beautiful built.
Glad you like it!
Those prices have gone waaaay ups!!!!!
bro you inspired me to build my own bike!
Crazy cheap. If you're in embt world you will know that is almost unbelievable for full carbon full suspension brand new emtb bike
Great video rob.
I have a bafang mid drive with the big brother the m600 great reliable motors.
Can't wait to see test run
If going flange mount, I would do the Bafang Ultra big watt motor as well versus the 510.
Well done Rob, great video.
Amazing video, bike and i love the motor! Please share sources. Thank you.
great job, bike looks a banger!
It looks pretty good ngl but what one thing has me thinking. Is the rear travel actually gonna be used? The frame's pretty tight and it doesn't look like it can withstand a 150mm travel on the rear because of the linkage. You might crash that rear linkage into your main frame if you use too much travel.
You know how every community has those guys who do all the stuff you do, but silly? Like Mini Cooper rally cars or AMC Gremlins with V-8's stuffed in them? I am that guy on an ebike. I tricked out a Jetson bolt. Well, am tricking out. I call it the Mediocre Bee 37.5.
When is the track test Rob ? I cannot wait. I think it will go very well. If it does not blow the comp away can u please not worry about the EU rules as given these bikes are offroad why not ?
This is YouTubing on the high level. Great job Rob
Use the 620 bafang with the denfung e22 frame man it will blow your brain.
