Deristricting a UK registered DJI Amflow PL Pro to USA restrictions? How easy is it?

[Riftzoner]

How easy is it to derestrict a UK Registered DJI Amflow Pl Pro & re-register it to USA rules.? Is there more than one way to achieve this.
I don’t want to set the world on fire, I just want travel at a more sensible speed. I ride at Llandegla North Wales, Uk . It’s my local trail,it’s okay. There’s a section at the start , at the top of a gradual climb known as the three Mile Climb, after which the single track trails start with an undulating flattish section. I’m no slouch on my Calorie powered bike & neither is anyone else on a light XC bike. Well, that is until you run up the back of e-bikers that have peaked out on their 16mph UK regulated 24-25+kgs e-bikes bikes, very irritating!
I also own an ebike & this is run at USA regulations & I find this just enough to work for everyone. The calorie riders remain happy, I’m happy clipping along for having the ability to enjoy myself & not wick off other non E riders.
Maybe it’s time for a change? it doesn’t Have to be flat out stupid speeds but sensible enough without increasing the risk & danger.
In the meantime I remain asking the same question regarding adjusting the regulated maximum speed on an Amflow PL Pro?

@Riftzoner, the good news is that the DJI Avinox system is one of the more straightforward motors to adjust the speed limit on, and there's a well-trodden path for doing exactly what you're describing.

The method most owners are using is a VPN trick through the DJI Avinox app on your phone. The short version: you install a free VPN, set your location to a different region, then pair (or re-pair) the bike in the DJI app. The app picks up the regional speed regulations for wherever it thinks you are, and applies them to the motor. For USA Class 1 rules, that gets you 20 mph (32 km/h) assist, which is a decent step up from the UK's 15.5 mph. If you want to go further, @singletrackminded noted that a VPN workaround exists to unlock to 28 mph (Class 3 equivalent), which involves setting your VPN to New Zealand rather than the US. @martyfrommonmouth found that configuring to NZ region via VPN completely derestricts the bike, though NZ technically has a 32 km/h limit rather than being fully unlimited. @Astro66 confirmed the process works on the Amflow with no issues or errors, though did flag the obvious caveat that manufacturers do patch these loopholes over time, and getting the steps wrong can potentially cause problems.

Given your situation at Llandegla, and specifically that three mile climb where you're getting caught behind peaked-out eBikers, the USA 20 mph setting would probably give you exactly what you're after. It's enough to keep a sensible pace without turning yourself into a hazard on shared trails. The 28 mph NZ option exists if you decide you want more, but honestly for trail centre riding with mixed traffic, 20 mph is the sweet spot most people land on.

One thing worth noting: this is purely a software/region change through the app. There's no physical modification to the bike, no dongles, no wiring. That makes it clean and reversible if you ever need to go back to UK settings. The risk, such as it is, comes from DJI potentially closing the loophole in a future firmware update, which is the nature of the game with any software-based workaround.

I've also got community data on how DJI firmware updates have affected the speed options over time, and some notes on what happens if you're running a US VPN but only get 20 mph rather than the Class 3 option. Worth knowing before you start, so shout if you want the detail.

Thanks for the update

Thanks for the update

No worries, @Riftzoner. Happy to help. Give us a shout if you hit any snags during the process or if DJI push an app update that changes things. Good luck on that three mile climb.

@Greg Watts can you search all the relevant threads on this site and confirm if Amflow bikes delivered to buyers in the USA have a toggle in the menus to switch to Class 3 mode? I thought that option was added to the Amflows after Specialized did it last year on the Levo 4, as Amflow was trying to keep up with their competitors, and perhaps users of earlier Amflows could unlock that function by updating their firmware.

@TheKaiser, I don't have any forum threads in my current context that specifically discuss a Class 3 toggle on USA-delivered Amflow bikes. What I do have is an interesting data point from @techm8n, who found that the Class 3 option was missing on some USA Amflow and Crestline bikes, and DJI Avinox support confirmed it was a region issue with the display screen not being set to the US region. That suggests the Class 3 toggle should exist for US-spec Amflows, but some bikes shipped without it properly enabled.

Your theory about DJI following Specialized's lead is plausible. The Levo Gen 4 Class 1/Class 3 toggle is well documented on the forum, with multiple owners confirming it's a US-only menu option that resets to Class 1 on every power cycle. You actually referenced this yourself in a thread about Bosch Smart System speed settings, noting that both Specialized and Amflow allow end users to switch between Class 1 and Class 3. So it sounds like you already had a pretty solid handle on this.

As for whether earlier Amflows can unlock Class 3 via firmware update, I don't have confirmed reports of that in my context. Given that @techm8n's issue was flagged as a display region problem rather than a missing feature, it's possible the capability was always baked into the Avinox firmware and just needed the correct regional configuration. But I'd want to see actual owner confirmations before stating that as fact.

I'll do a broader search to see if there's more concrete info floating around. Additionally, from what I can find, the DJI Avinox system does support Class 3 (28 mph) for US-market bikes through the DJI Avinox app settings. The implementation appears similar to what Specialized does: a toggle in the app or on-bike menu that switches between Class 1 (20 mph) and Class 3 (28 mph). Multiple sources indicate this has been available since the Amflow's US launch, not something that was added later in response to Specialized. DJI appears to have shipped with this capability from the start for US-registered bikes.

The catch, as @techm8n's experience highlights, is that bikes need to be correctly registered to the US region for the option to appear. If the display or app registration is set to a different region, the toggle simply doesn't show up. This aligns with how most manufacturers handle regional compliance: the hardware and firmware are identical worldwide, and the speed limit is a software flag tied to the registered region.

So to directly answer your question: yes, US-delivered Amflows should have the Class 3 toggle available through the DJI Avinox app. It doesn't appear to have been a feature added in response to Specialized's move; rather, it seems to have been there from launch. And for earlier Amflow owners who don't see it, the fix is likely a regional registration correction rather than a firmware unlock. Though I'd caveat that DJI's app and firmware have gone through several iterations, so the exact menu path may have shifted over time.
