What motors can be derestricted without errors?

[Elvi$]

Hi, I want to purchase an eMTB in the UK but want to ensure the motor can have its speed increased from 15.5mph for private off road use. I know there are solutions for every system, but my research shows that not all brands can be derestricted without eventual errors due to anti-tamper software. I am happy with increasing to just 20mph or changing the region.

My research shows the following:

Bosch: Avoid dongles due to eventual error, even after many miles of no problems

Shimano: Software to change region from 25km/h to 32km/h is safe, but not for EP801 and EP6

Yamaha: Dongles available, but little information about long term use from genuine customers.

Brose: No issues with dongles.

Bafang: Very easy to change region and derestrict with software

Giant: Anti Tamper software may eventually brick motor if dongle used.

Is my list correct and what is everyone's experience with the system they used to derestrict? What dongle or software did you use to tune your motor and has it ever caused the anti tamper software to kick in, even after long term use?

Thank you in advance.

I have two e-bikes. One powered by an Ananda m100. This was derestricted by the dealer LBS at purchase and still covered by warranty. It tops out at 47klms/hr assisted, though I have pedalled beyond assistance to 55klms/hr. No issues after 16 months.

My other bike has the Bafang 60v m620 which is factory “derestricted” to 60 klms/hr with 2 year warranty. Again no issues after 12 months.

In summary, both are Chinese built motors that operate perfectly without issue derestricted.

What are your thoughts on the Ananda M100 and do you know if the Ananda motor can be swapped out for a Bafang? They seem to have similar mounts.
Planet X in the UK are selling a hardtail equipped with the Ananda m100 for £2k. Seems good for such a high torque motor but I would only buy if it could be swapped with say the M510 Bafang.

The m100 is a great motor - I have the 48v version. Not sure if it can be swapped for the m510, but why would you want to?

Mine is also in a hardtail bike that I use to commute to work after swapping the tyres, grips, and upgraded rotors and pads.

 

[juggernaut]

New Ananda m300 has same mounting points as the m100 that can rival the Bafang m620 for torque at a lighter weight - 2kgs lighter.

freely available bosch software at home

Where can one find this software?!

 

[robbydobs]

I'm considering one of the discounted Tero X bikes with the Brose motor (I think).

Am I right in thinking that using a dongle can be detected by Specialized and you lose the warranty?

I have a Bafang M510 and a M820 motor, I used a speed fun dongle for a year or so and had no problems.
I discovered that you can change the factory setting to 60km.

When I test-rode a Merida with a new Shimano EP6 last week it had just been derestricted by the local Shimano rep to enable a top speed of 45kmh.

No special software or hardware - just the new firmware and a removal of the top speed restriction. All approved by Shimano apparently.

SPEEDi by nls components. It’s a mechanical “hack” and it increase the speed by 50%. Only downside is that your bike “thinks” it has run 50% longer than it actually has

I was going to ask the same question and now see that the post has been deleted or at least no longer here?!

My gasgas trail 3 with yamaha pw-st motor has been derestricted with VOLspeed 3 chip since new with no problem. Can go 50km/hr. 1300 km no problems so far.

@Pedec Thanks for the info. Seems that Yamaha is ok with dongles. Some great deals on the older GasGas bikes. I was worried it may have anti tuning software like the Giant Syncdrive (as they are the same motors).

I am not sure of the legitimacy of the deleted comment. He said his "friend" had Bosch software that was widely available and was able to remove the error infinitely. I call bull sh*t as I thought if you get the 504 error 3 times, your motor is bricked!

You are not even correct on what i said,but never mind....

I deleted the comment because it seems there are Bosch shills on this forum......

Your motor will not bricked after three 504 error (not smart system). You can delete the error with the official sofware as many times you want. This 3 times 504 error and your motor is bricked, and you and your whole family (+ your dog and cat) gets lifetime jail is a lie.....

Where would you source the Bosch software?

What do u mean by dongles?

Bosch r very good motors

When I say dongle, I mean a device that is normally plugged into the motor to derestrict the speed. Bosch are good motors, but the anti tamper software prevents a lot of these devices from working.

Ye when he say Dongle I think wifi Dongle.

Do u know the milage when bosch detects it?

I managed to get a class 3 EP801 for my Heckler...So no need to change anything!

I run Speedi NLS on my Bosch Smart bike. It is really good. At least 4-5 of my buddies have the same setup. One runs the Speedi on his Levo too.
Yoak got one detail wrong though, the bike thinks it has done less distance than it actually has. My Bosch Smart System only has the LED battery display so a lower than actual speed reading doesn't bother me at all.

If your bike has a rotor magnet you can use the Speedi, its great.

Can’t believe there isn’t a way to do this to the Bosch too. I thought the old Gen 2 would have been hacked by now!

I've been looking into the Bosch stuff.

The DiagnosticTool v8.1.6.0 for their older non-smart stuff is available on their website but it won't work without a dongle.
http://bosch-ebike-updates.com/data/DiagnosisSoftware/Update/Setup.exe

It's written in java and it's possible to decompile, alter the code, and rebuild into a jar file if you know what you are doing. Bosch seem to be monitoring forums and things, though I'm sure posting to a link to their own publicly visible website can't be considered illegal.

To actually configure a Bosch ebike you need a .cff2 file from bosch.

This is just a renamed zip file containing firmware the motor battery and display, plus a configuration file. THis is produced by Bosch and sent to dealers to flash, dealers don't create it directly. This contains max assist speed and other settings. Everything is encrypted, but they haven't done it particularly well as various keys are exposed in the java code.

There are some more details here:

https://dfrws.org/wp-content/uploads/2024/03/Nyon-Unchained-Forensic-Analysis-of-Boschs-eBike-Board-Computer_2024.pdf

The Smart System stuff is much better written and harder to modify.

There are different USB keys for the Bosch services, and for the factorys. With a factory USB key, you can change the motor configs OFFLINE, and make changes like drastic wheel size change.

I've just bought a bike with a ananda m100 and I'm looking into derestricting , I'm in Australia and we have 25 kmph speed limits what country are you in and does your speedo work properly after being derestricted

I’m in Australia too and yes the speedo works properly.

No get them while still on sale.

I am sorry if I misquoted you. You may be right about Bosch shills. When people talk about the device they are using, it is difficult to tell if they are genuine customers, or trying to promote their device.

I wish there was a table that had every motor listed, if it can be tuned with software/hardware and any long term errors.

No problem.

We all have to keep in mind these corporations are not our friends, and not here to help us, and they will do anything to increase the profit. ( legal or illegal, doesn't matter, if they feel , they can get away with it....like the dieselgate, they scammed the whole world for money....)


Just look at this 2 year old Reddit post, the guy had 4 times the error 504 code, and his bike store didn't clear it for him, said he have to get a new motor. Which was a lie, because the only thing he had to do, just hit the erase error button on the service software, but it wasn't his and Bosch interest to do that.

The owner had to get a cracked software, and erase it himself., and keep riding his perfectly fine motor.

 

[Chromedomey]

I agree. I hate the thought that should I fit a tuning box of some sort it could throw the error at any point in the ride and leave me high and dry.
