Hi there,
I hope you’re doing well. I’m reaching out because I’ve noticed a rattling noise coming from my AmFlow motor, which I’ve ridden for about 300 km now. Initially, I suspected it might be due to the cables in the frame, but I’ve since observed that the rattling only occurs when the motor isn’t under load. For instance, when I ride over roots, the noise is noticeable; however, as soon as I apply power—while going over roots—the sound disappears.

I had expected the motor to operate quietly, especially while descending trails, as I deliberately chose AmFlow to avoid the kind of noise produced by systems like Shimano. Could you please advise whether this rattling noise is normal, or should I consider contacting my dealer for a possible replacement?

Thank you for your time and for being actively involved in the forum!

We'll make sure to get back to you with the latest delivery information within three business days~

Hi @Amflow_Support

Amflow Customer Support have got back to me and told me that the bike will not be delivered until early May. How is that possible, when I ordered the bike 6 weeks ago, and if I order one today from your website, the site says it will be delivered on the 28th of April ?

I am extremely disappointed with your ordering process, when I was told it should be 6-8 weeks delivery.

It gives me very little confidence if there are issues in the future, when this is the service delivered, once you took my deposit.

Below is the order form from your website right now, showing an April 28th delivery.

Hi Customer,
Since the release of Amflow PL, it has gained considerable popularity among users. Amflow is very popular in AU market. Presently, Some models are out of stock, but we are actively working to replenish our inventory.
If you place the order from our official website today, you can expect to receive the bike on the 28th of April.
And for your current order, we recommend you can keep in touch with your dealer, thank you for your understanding.

hello,

I have a question related to frame warranty and fork :

- If i install an upside down fork INTEND with 35 mm stanchions, 170 mm travel on my amflow : will it void the frame warranty ?
( i.e. do upside down forks void frame warranty ?)

Thank you

Hallo Gigs! Zu deiner Idee: Du kannst den Raddurchmesser in der App auf 27,5 Zoll einstellen, aber ein 29-Zoll-Hinterrad verwenden, um etwas mehr Geschwindigkeit zu erreichen. Da Unterstützungsalgorithmus, Route und Geschwindigkeit jedoch miteinander verknüpft sind , empfehlen wir, den Raddurchmesser in der App so einzustellen, dass er der tatsächlichen Radgröße entspricht, um optimale Fahreigenschaften zu erzielen.

Wie kann ich eine individuelle Radgröße einstellen. Bisher kannte ich nur die Wahl zwischen 27,5 und 29 Zoll. Bei meinem Amflow wird die Anzeige um ca. 5% zu hoch angezeigt, was sich auch auf die gefahrenen Kilometer auswirkt.

Moderator Translation :

How can I set a custom wheel size? Until now, I only knew the choice between 27.5 and 29 inches. On my Amflow, the display is about 5% too high, which also affects the mileage.

*** Please continue further posts in English. It's easier for everyone to follow the discussions.

Unfortunately, our software doesn't currently support setting other wheel sizes. We'd be happy to pass on your feedback to our engineers.

The Amflow PL's geometry is primarily designed for a 160mm travel front shock. However, we have tested it with a 170mm travel front shock. So, if you need a longer travel front shock, you can upgrade to a 170mm one. Please note that this will alter the bike's geometry: the head tube angle will shift from 64.5° to 64.1°, the seat tube angle from 77° to 76.6°, and the bottom bracket height will increase from 345mm to 348.8mm. Please consider these changes based on your riding requirements. If you want to install a different shock/fork, make sure it doesn't interfere with the bike frame when you're riding, then the warranty will be fine.

It is always good to check with the manufacturer but, for what it's worth, I have never seen a warranty with a prohibition on upside down forks. Many do prohibit dual crown forks, but I am assuming you are talking about the single crown upside down models from Intend, as you only need to go dual crown if you are trying to get in the 200mm travel range.

You are right though, that upside down forks probably increase stresses on the head tube area, as they have greater for/aft stiffness, but that is also true of any larger diameter fork, so if you got, say, a 38mm right side up fork, it would put greater stresses on the frame than the stock 36mm or 34mm fork, even at the same amount of travel.

I'm curious to see what turns out to be the culprit here, and how AmFlow handles the issue. From your post, I was unclear, do you think this rattle has existed right from the start or did it happen after you'd ridden a couple hundred kilometers? Asking, as one would indicate a fundamental trait of the motor, and the other would indicate something going bad after some use.

The early preproduction press review models of the DJI motor/Amflow bikes apparently did rattle, but then, due to clutch rattle being such a common complaint in the e-bike world, they (to their credit) revised the motor within a few months, to apparently minimize or eliminate the rattle. Again, I want to give props to DJI for being so responsive to user feedback, as it took Bosch many years to fix their rattle, and Shimano still hasn't. Having said all that, I was unclear when they started delivering bikes, and if any actually went out to consumers before the changes were made to eliminate the rattle. I was seeing reviews complaining about rattle last Summer, and other reviews in the Fall saying the rattle was gone. When did you get your bike, and do you have any idea if it might have been one of the very early ones off the production line?

I had a slight very rattle on my AMF Pro from new lasted a couple of rides, shop said it will stop and around 50 miles and it did. The Motor is the most silent of any E MTB i have ridden, not had a single problem ,Love the bike 700 miles in now every time i get on it just blown away with the power and how smooth it is. I do use Turbo and boost a lot hence required new Chain and Cassette and 370 Miles. My S Works used to last around double that bust worth the cost for fun on the AMFLW

 

[Ridgydidge]

I notice the odd momentary rattle when I’m banging downhill and I’m downshifting to a smaller cog. On such downshifts I usually backpedal and pause to allow the overrun to almost stop, to avoid chain snatch. In those moments - before I pedal on again - when the clutch is thus not engaged - I can get a rattle. But otherwise, no rattle.

Hi Amflow Support,
I got my Bike on Monday, ton of fun until today. Suddenly got the worst rattle one can imagine. It feels like the whole bike is going to fall apart..seriously something is really wrong with the DriveUnit.

Thank you for reaching out to us about your recent experience.

Could you please let us know if this problem started happening just yesterday or has it been ongoing? If it’s a new issue, you might want to try removing the crank and checking if there’s any looseness or slipping between the crank and the motor shaft. If you find no issues there, reinstall the crank to see if this improves the situation. Please note that the crank removal and installation requires 8mm Hex wrench only, DO NOT use 10mm Hex wrench on the outer crank bolt cap.

If the problem persists, we recommend contacting the store where you purchased your bike or getting in touch with us directly at [email protected] for further assistance.

As I do not have a action cam and it is only noticeable when driving over roots or rocks I have no way to take a video.

I had this rattle since the beginning. Took me some time to pinpoint the rattle. First thing I thought of was the cables rattling to the frame. Put some churos around the cables and I'd didn't make a difference.
I bought the first bike from my dealer in November last year.

Thanks for replying to my post.
Can´t see how tightening the cranks could solve this problem, but cranks are tight on the shaft. In fact they were so tight, while trying to remove the non chainring side crank, the the threads stripped as shown in attached pictures. while trying to use the bolts from the crankside to get i off it stripped the threads too. A standard crank removal tool doesn´t fit the original Amflow cranks. Left crank is still on. this is getting funny now...

Ha… ‘in a quiet environment’ is impossible.

Look it’s no biggie, the odd rattle when the clutch is slowly being re-engaged while battering down chunder at warp speed.

Really, the motor is so far superb. No issue from me.

Crank is off. In Case someone else is running into this Problem. You need a Rotor Puller M27x1.0mm left-hand thread. The driver is not long enough to push on the Motorshaft, so you have to modify it like shown in the pics.

Thank you for bringing this to our attention and sharing the details with us. The cranks on our bikes use a self-extracting bolt system, which allows for both removal and installation using only an 8mm hex wrench. There is no need to remove the bolt separately from the crank. This should ensure a smoother process overall. We’d like to apologize for any confusion and inconvenience caused. Should you have any further questions or need additional guidance, please don't hesitate to reach out.

thanks for your reply. i think anyone knows how to remove cranks with a self extracting system. its straight forward. ....in my case the threads of the Mx27 Bolt stripped right off. compared to other self extracting systems its a bit flimsy.

Bike is running mint so far, but i found out roughly since the latest update the temperature measurements on the display are not measured anymore (current, min, max). Only " - " is shown in the temperature section whereas in my Avinox App, i can see motor and battery temperature being measured.

Already tried removing and adding custom screens, restarting, resetting, disconnecting the display cable - no success. I remember the temp being displayed last year before the update.

Not a vital function i need but i wanted to inform. Could be a software bug - could be a defect of my sensors.
