Dengfu E10 - The CHEEB V1.0 - Discussion

[Timmy65]

OK I did 10K yesterday on the new M500 motor.

Power is most certainly more and the bike feels much more responsive:

- In level 3 peak power is reached much quicker with slower cadence and less rider torque
- Power was showing at 500w+ on the display constantly on hills, rather than just occasionally on the previous motor
- Seems to be a small bit of overrun (bit like Bosch) after you stop pedaling

Still not quite as instant to engage up to full power as some other motors. Requires a couple of rotations, but its a fair bit different to before.

Also, I asked Bafang about the differences. Here's what they say:

1. The hardware is changed from existing M500, we changed winding turns from 19T to 15T in motor and 6 FAMOS to 12 FAMOS in controller.

2. The firmware/software is also changed. The response time of motor start changes with torque, torque response is faster, constant power output of high step frequency, constant torque output of low step frequency, etc

3. Because of the hardware changing, we can not update firmware at existing M500 to achieve the same performance.

Good to hear they updated the motor, hopefully i get the new ones i ordered.

Y'all are so luck to order the Dengfu E10 since Melody has not replied to my request of purchasing it yet. I hope to hear from her very soon! It's wait and pray time ?

There might be a lot more other things to pray for in these times ?. I think they are just overload with requests and work as Chinese New Year just passed and they were out of office for 10 days. Melody normally answers within 1-2 days. I placed my order on january 18th and will not get anything delivered before beginning april ??. How long are you waiting for feedback now?

No, thats a totally different frame (older one I think).

Jtran69 Are you being quoted for the whole bike

No, she quoted me for the 3 items that I had requested.

 

[jtran69]

No, she quoted me for the 3 items that I had requested.

Adding more info: she quoted me that once payment is completed, it'll take about 30 days to produce and 12 days to ship to USA.

Some info for painters:

In attachment are paints available from Dengfu. Single color paint 85 USD, 2 colors 105. Against black matt default color expect significant longer delivery time (+1 month). Also when ordering, extra rear derailer is 8 USD. Seat clamp is usually part of delivery of frame, doest not need to be bought extra (maybe its part of headset, i dont know).

What is differences between 170mm Rockshox Zeb fork and 160mm Rockshox Lyrik fork? which one is better?

 

[thaeber]

Is it possible to install a Cane Creek Angleset? Is the headset delivered with the frame semi integrated (ZS) or fully integrated (IS)? Are there cups that need to be pressed into the frame?

I have installed an adjustable headset on my E10, but you have to edit the head tube a bit.

Exactly what I need! Did You rework the dia or the depth of the Headtube?

Only the depth has to be reworked by approx. 4mm

As far as I know headset is not delivered but there has nothing to be pressed in the frame as it is set up.already

After checking Dengfu E10 info‘s again, its pretty much clear now that the frame is designed for 29“ wheels, and 150 mm suspension travel front and rear. This fits to the geometry change that Rob provided, with mullet setup and 170 mm fork. My assumption was that the frame is designed for 27.5“ wheels, that was wrong and caused me some headache . So I will go with mullet setup as well, 180 mm fork, and 216 x 63 shock and offset bushings to fine tune installed shock length.

wow serious cushing to the max man! May I ask where are you ordering your rear shock and offset bushing from as I might go the same route?

Just be a little aware how slack the head angle all ready is, I'm running 150mm approx front and rear on 27.5 fat 2.8" tyres ( almost the same OD as 29 " 2.4" and for my X Country stuff I do, the frame already is verging on getting that dull steering feel on tight slow single track you get with too much head angle. You start pushing up the front further and yes you will get longer travel but you will loose some of the nimbleness together wiith the higher BB creating that on the bike rather than in the bike feel. Just a personal take on things I guess.

Hm, all parts here, only frame & motor are missing to start. And also offset bushings, but i expect them this week

PS: for builders -> situation on sale market with parts is becoming more and more problematic. Be prepared!

 

[Sunburntwily]

Parts are coming in dribbs and drabbs. Forks came today that raised the question does the E10 frame come with a head set? I'm guessing not. So no idea what to get, any advice please. Also I thought as I was going the so called cheap Chinese rout I would try carbon fibre wheels aswell. I shall let you know when they arrive. Not sure how wheel hubs work as the price range is crazy. I have a concrete grinding business and normally have to replace bearings (Chinese) with new Japanese bearings. I am assuming this is possible with wheel hubs aswell. Anyway perhaps not. I am enjoying the journey so far.

head set is basicaly proposed in intial offer by dengfu, if customer does not remove it => it is provided

 

[thaeber]

Plan is to order the Zeb Ultimate 29“ 180, the Vivid Coil ((Super Deluxe is not available in 216 x 63) or the Vivid Air, from wherever available at best price in Germany. Offset Bushings directly from offsetbushings.com in GB, link was provided by Rob in the build thread. I ordered bushings before there, with no issues. Completing with XT 1x11 drivetrain, 34 chainring and 11-46 cassette. MT 7 brakes, Bikeyoke Seatpost, Handbuild Wheels, Schwalbe Big Betty and Magic Mary 2.6, tubeless. Cant wait to start!

I calculated based on Dengfu geo chart, and the assumption this geo is based on a 29“ wheels with 2.6“ tires. With that, the longer rear shock and the longer fork, the headangle will be at 64.2 deg., BB hight at 358 mm. So far thats the theory ?, if this turns out to become reality, I‘m fine...
