Dengfu E10 - The CHEEB V1.0 - Discussion

[goRt]

then those are the wrong ones .... you need to remove them and replace by 16mm bushings ...

RockShox Bushings for Struts 8 mm metric/imperial

These RockShox bushings with 8 mm diameter are used to mount your RockShox shock, regardless of whether it has a measurement in millimetres or inches. Compatibility: RockShox shock with 1/2" (12.7 mm) shock eyelet Manufacturer Numbers: 14.0 mm: 11.4

www.bike-components.de

You can use a special tool RockShox Rear Shock Bushing Tool For Slide Bushings

or a hammer and the right inserts or sockets from a socket wrench to hammer them out

I've ordered the tool with the bushings (although I have a selection of large hammers)

Rob clearly wrote (but I thought it only applied to offset):

You’ll need some shock hardware. The size is as follows


16.5mm x 8mm linkage
32mm x 8mm frame mount

I got mine from @Offset

Thanks for the order sir!

It looks like the other chap received wrong size bushing from Dengfu or their shock manufacturer. Rear bushing is 16.5mm in width - we produce them almost daily now for E10 owners in fact in both standard drilled and offset.

Thanks,

Jeron @ Offsetbushings.com

You should have ordered 16.5x8mm and 32x8mm bushings from Melody right away, as I did, and they fit perfectly. And only for the price of 8usd ...

This thread is for generally discussing "The CHEEB" and the DENGFU E10, opinions, thoughts and so on so as not to clutter the main Cheeb build thread so it's easier for people for find technical information. Technical discussions and build information can be found in the main CHEEB build thread here :

My Chinese frame and motor build. The CHEEB, V1.0 - Build Thread

This thread is the Official Technical "CHEEB V1.0" build thread. Most of your questions will probably have been answered if you read through the thread, so please take the time to do so before posting a question. If you just want to "Chat CHEEB" there is an alternative thread ...

Motor and battery arrived a few weeks ago. Bafang M500, 95nm, 48v system with EU 250w rating. Battery is a 840Wh huge in tube battery.

Frame:
Full Carbon frame set with fairly (by China frame standards) modern geometry.

I ordered the XL, 510mm in reach. HA is 66 degree but I will run bigger fork and mullet, so likely end up around 64.5 ish.

The frame is from Dengfu. They even supply full leverage curve, anti squat, pedal kickback etc graphs and figures! No idea of accuracy, but at least they are included

Frame is called the Dengfu E10 and here is the link. For some reason its labelled as E11 on the charts, but the Dengfu E10 is the actual product.

Ebikes are getting crazy expensive. Many brands are hitting over £10,000 for the high end builds.

A lot of people would like to get into ebiking but the big barrier to entry can be the price.

Can an ebike be built at a reasonable cost? What if you already own a lot of parts and would like to put them towards something new?

Since frame / motor sets are pretty much non existent in the ebike world, this seems like it could be a viable option to build your own decent ebike at a very reasonable price

I want to build a full carbon 170 / 150mm travel ebike for under £4k. I’m also super curious how it’ll perform against the big dogs.

I want to see what the associated risks of doing this are.How long does it take, shipping, warranty, build etc etc.

It’ll have a RockShox Zeb, Super Deluxe ultimate, DT Swiss H1700 wheelset, Shimano 10 speed drivetrain, and yes, it all comes in at less than £4000 for a full carbon ebike with proper components.

Goal is sub 24KG. I think I can do it!

COSTS:

The frame set, battery and motor costs, including U.K. Shipping and duties had a total cost £1,694.44

Current total build cost, even including tyre sealant is £3888.55. This could further be reduced by ‘downgrading’ fork to a Lyrik, the Shock to a Select, and the wheelset to a H1900 set from DT Swiss. With that kind of setup it’ll be around £3400.

You’ll need some shock hardware. The size is as follows

16.5mm x 8mm linkage
32mm x 8mm frame mount

I got mine from @Offset

Frame has arrived and so far it seems great. Finish is good quality, cable runs seem decent. Includes headset bearings, seat tube clamp, steerer tube expanding head doctor thing (bit like Hope's version), battery release key, wheel axle, bottom battery cover that can be removed with hex keys (x4 bolts).

Hi Rob just out of curiosity, what psi was you running on your rear shock?
Many thanks

Hi all, I have seen one chat on the E10 lower battery charging point, but don't seem to have a nut to go on inside of the frame the back of the connector to hold it in place. Did anyone have the same problem?

Thanks, I found it in the end, it was in with the keys for the battery lock, go figure. Tried ordering some from Amazon but couldnt get the correct size.

I’m having a problem with my m600, any advice would be much appreciated.
I was riding last week with about 60% battery left and then the bike cut out. I turned it off then on again and it was showing 1% then cut out. It continued to do this after trying a few times. I then tried turning it on using the button on the bars (under the +/- power level buttons) leaving the one on the side of the frame (next to key lock) off and it went back to 60% and rode fine.
It now is doing this all the time and there is a gritty sound when I press the on button on the side of the frame like sand could have gotten inside.
Anyone experienced this/ any advice?
Many thanks, Dan

Sounds awfully like my experience. There's a thread I posted somewhere on here called "cheeb issues" or similar. Have a read of this and see if it helps. (Short version, sounds like something is wet. Use a hairdryer to dry everything thoroughly).

You absolute legend, I’ll get out there and have a go at drying it out, many thanks

The UK is in real mudsville terrain at the moment and I've been having some trouble with the standard Bafang front crank ring catching the chain when full of mud and wrapping itself fully around the ring ( chain suck ). The chainguide has consequently taken a beating and finally after tightening it again for the umpteenth time, I fully removed it and fitted a standard 104bcd 36T narrow wide front crank ring.

Been good so far and not had any problems with derailing nor chain suck. Do we need the chain guide, possibly not.

BB is at 358 mm with mullet wheelset. Sounds high, but considering 170 / 180 mm travel and 30% SAG according to my preferences, perfect. Almost no pedal strikes with standard 170 mm cranks.

I'm planning on doing a mullet setup and have got a 210x55 rear shock, but working out if I should go for 180mm or 170mm travel for the forks. Trying to work out how this would impact geometry / BB height. Will I be regretting this if I go for 180mm and not having 216 x 63 mm on the rear?

 

[thaeber]

With 180 mm It will drop Your HA by appr. 0.5 deg, and lower Your BB apr. 8mm. Not really a big thing. May be it will feel a little unbalanced due to the difference in travel 180mm vs. 150mm. I would go 170 mm on the front.

I did it. Took her out for her first run. Been doing the final touches over the last week like mudguards and chain guide. I will post all the specs later but its the Bafang M600 on the E10 frame with 27.5 wheels front and back, Rockshox Yari fork, Fox seat dropper, 11 speed cassette, Brooks Cambium C15 seat. Very comfortable ride, a few pedal strikes. Rear shock needs stiffened up a bit. Motor very responsive and quiet. Got to 34 kph on flat with throttle. Motor made some noise at top speed. Cant wait to try in on some trails, though these country roads are almost trails, potholes, mud, field muck, etc. Really enjoyed building the bike. Thinks that need tweaked are the rear shock and spongy rear brake.

Does anyone know what size dropper post a size medium frame can handle?

Nice chameleon!

 

[patdam]

does somebody know the pantone code of this color ? does it existing pantone code of this kind of paint (chameleon) in color more clear ?

It's not listed on the pantone code. Sale rep can show you a few changing paints option and mine is also chameleon

 

[patdam]

nice. but light carbon (alike dengfu) request pantone code for custom painting.

Great thanks! The 170mm Brand X dropper I'm eyeballing should work just fine then!

Yes, mine. At the begening when the motor is hot (after +- 1 hours of ride), the on/off button sometime do not acting. In first i have removed the timer to switch automatically off (to don't be blocked during exit). At the end one day, i can't switch on. In same time i had fighting with dengfu/bafang (during 3 months) to purchase an controler (without solution), i had finished by ordering an complet spare motor, bafang have also accepted to repair my motor, i have sent the controler/diplay/wiring to the Eu service center. They don't found failure, but they have replaced the controler. i have received the two, new motor and new controler +- in same time (2 week after complete fails). since no problems. Now, it seam you can buy controler. I recomand to check all connections before change something.

I checked all connections and all are in can you tell me where to buy new wiring and controler from thanks for reply

 

[patdam]

For me it was not a problem of wiring, i have checked with another one stored in spare (display, remote, cable to motor) and the problem still occurred. I can't recommend a controler supplier in particular, because i haven't purchase one. But if you search a few, you can find now several supplier who propose it. But may be you ccan try also to initiate warranty request ?
