How did you get the wattage and calorie to record ..? .. I'm completely new to Strava. I took a short ride today and it only had distance elevation speeds and time.

I think it automatically calculates it based on your weight, and bike weight. You have to enter this into your profile I think. Then it just looks at the GPS data, elevation, speed etc and calculates it.How did you get the wattage and calorie to record ..? .. I'm completely new to Strava.

What did you figure out @Tomteam? Just looking now myself and pondering a solution, current thinking is this:I am mounting my E22 and I have doubts about where to place the shift sensor.
I've thought about putting it inside the frame, where the shifter cable runs over the battery box.
Any ideas?
Hey Folks
I've just opened the box containing the headset that came with the frame, not seen anything like this before...is the idea that this effectively gets away from the need for a star nut? If so is it any good (and will it'll bugger up the steerer? I'm thinking about getting one of these nifty EDC setups at some point).
Cheers

cheers, anybody else using this stock part without issues?My headset kept coming loose and I finally figured out that was the cause. I replaced it with a properly set star fangled nut. Problem solved. I think those are mainly used for carbon fiber steerer tube forks and being a CF company DengFu sending them out that way kind of makes sense in all but practicality.
Thats called a compresson nurl, at least in the US we call it that. I used the star nut that came with my fork . If you have a fork that uses that then sure if not I would go by what your fork manufacturer recommends. The stock headset screw works fine with a star nut.Hey Folks

I don't use the shift sensor at all just takes a little learning on how to shift when not under load. To me it's just a added thing that can fail and if it's buried in your frame you hoofin home. Just my mho.What did you figure out @Tomteam? Just looking now myself and pondering a solution, current thinking is this:

Hear you, but there really isn't much to go wrong.I don't use the shift sensor at all just takes a little learning on how to shift when not under load. To me it's just a added thing that can fail and if it's buried in your frame you hoofin home. Just my mho.

Ha! not seen that before.Use Self-amalgamating tape!
It will keep moist out and bond it all together.
Keep up?! She’ll thrash you.Hi guys.
I've decided to buy an E22, so that my girlfriend can keep up with me on the E10...
Question, though... I am told by Dengfu that there are 2 variants - one with a round charging port and a newer one with a square one.
Is the square one a V2 frame or something, or is it merely a small tweak confined to this area.
And, secondly, is there any reason why you think this change might have been made? Are there issues getting good connection with the round 1st gen one, for example?
I only ask because I'm told that there will be a longer wait for the square charger port version.
Let me know if anyone knows.
Cheers in advance!

That amazes me that your burning up cassettes so fast, I already have 100 miles on my sram 12 speed gx and zero signs of wear. I'm wondering if your use of the throttle as you've described is putting abrupt tension on your system resulting in such quik wear. I know your watching your heart rate because of your illness. But I'm wondering if a little peddelling just to ramp up the motor before applying throttle would help. I'm just throwing it out there. I don't know much about internal hubs but I k ow Luna puts one on one of there bikes and has a good track record . I k ow there not cheap.Alright guys. So I've inspected my cassette. And it's showing signs of wear on the 4th and 5th gear. I mostly use the 4th and 5th gear with the 9spd setup. It isn't slipping over the teeth yet, but looking at it, I think its going to happen soon. You can see the gaps opening up as the teeth wear away.
I am seriously considering internal gear hubs at this point. Replacing cassettes every 50-100km is not sustainable.
Looking around, I have seen 3 different options that I like the sound of. Firstly, the 3x3-nine, then the Kindernay VII, then the Revolute Hub 1.
The 3x3 is a 9 speed ebike specific gear hub. It's got 9 speed, quite large gear steps. And can take high torque. I contacted 3x3-9 and they said it's only available as an OEM choice starting next year, with hopefully individual sales following. So that's 2023/24 at the earliest, too far away. But I like the sound of this hub the most.
The revolute is a 6 speed (plus neutral), can also take high torque. It won't roll back, unless in neutral, which is interesting. It sounds like quite a good choice aswell. But it's only available pre-order now. So probs won't see it until next year aswell.
Then there is the Kindernay VII, a 7 speed, with large steps between gears, also a very promising choice. They do list input torque at max 160nm though. Which depending on input sprocket sizing, could be on the limit with a rated motor torque of 160nm, plus leg power.
Are there any other options worth considering? I'd briefly look at rohlof, but they won't sell 148x12 spacing except to OEMs. Plus 14 gears with very closer ratio steps is not a good choice for ebikes IMHO.
I would get whatever frame you can the quickest. Not sure what difference round or aquare charging port would be. As long as the harness fits and charges the battery it's good to go in my book.Hi guys.

It's not like I don't pedal. I do. I just use the throttle, alot. I pedal a bit to get about. And use pedals to change weight balance, and give a little power when needed. On the ups, I use throttle a fair bit to get back up the hill. And on the downs, I use it as a little turbo boost here and there in between features, after corners, before jumps etc.That amazes me that your burning up cassettes so fast, I already have 100 miles on my sram 12 speed gx and zero signs of wear.

Interesting.I didn't know about the charging port differences.
But one possible explanation is it is a requirement or alteration specifically for a bike brand like Luna or WattWagons or similar. They might have a larger order, and only want the square port. But dengfu might have multiple moulds to manufacture the frames. And the mounds using the square port are all booked up full filling a possible large order, and the other mounds with round charge port are not in use.
So, I've been messing around with the Eggrider v2 display on my E22
<images>
At first, I thought some of the functions the display/app offered, would be overkill for EMTB. But I am truly impressed with the ability to examine rider data after each ride. Not to mention, it is the smallest display for Bafang ebikes. And the ability to export this data and upload it to third party services like Strava, is not lost on me .
Huge shout out to Eggrider for the hook up. At present, they are out of stock but I'll do my utmost to keep you all posted on stock availability.
A full video and written review coming soon

I use it alot. But I dont think there is such a thing as over using it. It's a bog stock motor, it's not modified. I'm using the standard firmware, the original components. I'm not using more throttle than is available to use.
These motors are supposedly 1kw. Another very common electric motor that is around the 1kw is automotive starter motors. They are often 1-1.5kw range. They run for 5 to 15 seconds at a time, but will do it hundreds if thousands of times, and they are usually extremely reliable.
The obvious difference between the bike gears and a stater motor drive pinion is the size and material. Automotive starter pinions have about 10 to 20mm wide gear teeth interface. And they are made of hardened steel. Unsurprisingly, they also practically never fail or wear. The motors will fail electrically. But the pinions never wear.
Bike cassettes teeth are maybe 1 to 2mm thick. And they are definitely not made of a hard steel. The box prime I currently have is manufactured as stamped steel. You can guarantee this will be a very soft material to facilitate a stamping process. Apart from a mostly cosmetic surface coating, I bet there would be no hardening treatment. Unsurprisingly, these are the parts wearing out.
As for cost, yes IGH are pricey. But if it has larger and harder gears inside, then it should last orders of magnitude longer. plus internally sealed and lubricated VS open and bathed in a muddy abrasive slurry like conventional systems... If you look at how much I've spent on chain / cassette already. I'm already half way towards an IGH.

Yes youve got to do something,, ridic getting new cassete every 200 miles . I'll be interested to see if my scram holds up it is definitely not cheap and of very high quality . As I said zero signs of wear so far after 100 miles .
Whilst I appreciate that I'm the OP/author, technically this thread has two authors.@Neeko DeVinchi or anyone else, have you thought about opening a wiki page for the Dengfu bikes in order to compile every information that has been gathered? Something like what @BonBond has done with the battery build thread.
Do you think the owner of EMTBForums would be willing to add a wiki service on this website?
Another solution would be to use your original first post of this topic as a summary of some sort although that would not allow anyone to easily contribute.
