All the talk in my area states that the Bosch Gen 4 motors can handle being derestricted and easily surpass the factory 2 year warranty. Keeping moisture out is a bigger concern than derestriction. I've ran a CX Perf Gen4 motor with old Purion controller derestricted for a year now. 1500 miles in and not one code. Had the bike at 26-36 mph several times for several miles and have never had one single code. Speedbox 3.0.

Awesome
Thanks for the information bud.

 

[ScubaDrunk]

1. better not, not before someone else dit sacrify himself to test
2. there is a version that enable you to finetune the predefined assistance modes (mine origianally did not had that option)
3. not able to use existing "tuners", Bosh is putting quite some efford in trying to discover "cheating". So using their app (gps) is not a good idea ...
4. as said, if you can get rid of the rim magnet, ie, enabling the traditional reed-switch (bike dealer), you will have much more options

Awesome
Thanks for the information mate.

I updated to the latest supported version 13.13.1 via the app. That unlocked the ability to fine tune the built in modes.

I will go for the speedfun rim magnet version.

With the rim magnet? If yes, can you share how speed box is making / generating the magnetic pulse?
Thanks

Mine is the old pre Smart system. The pickup is on the rear brake disc.

Was just wanting to give information about the durability of the Gen 4 motors. I wouldn't worry about needing warranty work done or having a failure caused by derestricting.

Has anyone came up with a solution for the Smart Systems yet?

Looks like Speedfun works with displays BUT doesn't support the connect module or the ABS system.

However, the display will only show a max of 15.5 mph and cannot show real speed above this limit.

Hello eMTB community, I'm new here with a wonderful 524001 error
I have a gen4 cx peformance on 13.13.1 software
I unplugged the derestricting kit (which was working fine before the error, it's from bikespeed.de), put back in place the rim magnet (yes I have the worst possible system to derestrict... discovered that after buying of course). Smartphone not connected.
Then I did the drill hack during 102min, no speed is displayed but average speed and distance are working.
After that I I turned off and on the bike and ... 524001 is still there...

Has some of you make the drill hack clear error with 13.13.1 ? Am I missing something?Would love to avoid ride it without assistance for 90min+? or take it to a service center ..

It could be a faulty speed sensor, either way it's likely you'll need to take the bike to a service centre to clear the error if the 90 min ride or drill hack doesn't work.

 

[cailloup]

I did a 100min ride, turned off, waited 10min, turned on, error is gone
Redconnected the kit, it's working again, unrestricted
So drill hack is not working on my system, there must be some detection of the perfectly constant speed, or inconsistent pedal power compared to wheel speed

 

[manu.w]

How did you do your 100’ ride?
Motor powered on, assisted eco, …?
Thanks

 

[cailloup]

When assistance was on, motor does "fits and start" every 1s or so (faster in turbo, slower in eco) which provides almost no assistance so I keeped assistance off
I did park the bike without pedaling during ~7min, but final trip time on the screen was 1h47

Hey guys,
looking to buy a bike with the bosch cx 4 Smart system and wanted to know how everyone is going with their unlock chips.

Currently Looks like the Volspeed seems to be the most reliable/least likely to occur detection? Has anyone come across any issues using it consistently at 40kmh + ?

Cheers,

Mines been detected twice now and gone into limp mode...I believe next time is permanent so I'm taking speedbox off .... Good whilst it worked but I don't want to trash a 3k bike....performance line CX gen 4 with smart drive

Hi guys last week I bought eplus Bosch smart system gen 5 with rim magnet, yesterday I tried to install in my new crafty RR 2025 unfortunately there is a problem,the sensor that install near the motor touch in the frame and not possible to put the bolt for fix the motor at the frame.

 

[ScubaDrunk]

So.....

I just installed the VolSpeed and Speedi. Did a quick test and everything appears to be working just fine.

However, I have noticed that the bike speed is limited by the gearing of the drivetrain now.

The realistic maximum speed (flat surface without killing yourself) you can get out of a Shimano XTR 1x12 is 25mph or 40kph.

What are other people finding that have simliar drivetrains????

What limit do you set the top speed to, 20mph, or above?
I think that the higher you set the deristricted speed to, the bigger the risk of issues.

 

[ScubaDrunk]

What limit do you set the top speed to, 20mph, or above?
I think that the higher you set the deristricted speed to, the bigger the risk of issues.

Exactly right

The general census is, try and keep the speed locked to below 24mph to minimize the risk of getting error codes.

However, Whats the point of running a chip if your drive train is going to be a realistic limiting factor!

You might as well run a Speedi Planetary gear magnet system with the motor limits - In the UK, 15mph limit on the motor with a Speedi Planetary gear magnet system equates to about 23mph.

If your drivetrain is a limiting factor that realistically is only going to give you 25mph, it doesnt make sense to me to run a chip with the added risk of getting errors when the Speedi will give you 23mph without the risk.

 

[Roberto6170]

I had mine set to 35km/h tbh I only wanted it to go just above the 15 mph so I good keep up with my mates who are quite strung cyclists

22MPH, you shouldn't really have had a problem with that.

[Roberto6170]

Unfortunately I have...2 detections with 49/59 mins in limp mode to resolve ..... I've switched it off now If I use it again I may not switch the bike off just lock it up and let it time out

[Peaky Rider]

As you say, "unfortunate".
Until tomorrow, I have had no such issues in over three years of use of a Volspeed V4 and a year with a Volspeed Smart System gizmo. Both are still working sweetly.
No doubt I have now jinxed things though and I will blame you if I have..

 

[Roberto6170]

Haha I'm sure you'll be fine... If I do get another detestrictor I'll get a volspeed ... They don't seem to be having these problems

I've decided to get this one for my One77 Bosch Gen 5 from

bikespeed - tuning for your pedelec or e-bike

Make your e-bike faster - tune it to 50 km/h and beyond with bikespeed systems. Professional tuning available for Bosch, Brose, Yamaha, Panasonic, TQ, Pinion, and other brands.

www.bikespeed.de

so I'll give you an update when it's all installed.

I've done a lot of reading and there are a couple of options for the Bosch Gen 5 smart system but these guys seem like they are ahead of the game with their software combating the Bosch detection algorithms.

You can also speak to them via WhatsApp and they reply relatively quickly and in English which is good to know.

Haven't had the bike delivered yet so it'll be a while before I can give feedback.

Hi everyone,

I've got a Bosch Performance Line CX (with Smart System) with drive unit software version 12.13.0 (have not updated since purchasing the bike). I installed a SpeedBox 1.1 a couple of weeks ago and had a 524001 Speed Manipulation Detected error after ~100kms. I was unable to clear it by riding for 90+ mins, so resorted to having a sympathetic dealer clear the error for me. Here are the exact details of the rides I did between fitting the SpeedBox 1.1, and the error occurring:

Journey 1 = 18mls, mix of eMTB and Turbo, generally riding at 35km/h
Journey 2 = 18mls, Turbo, generally riding at 35km/h
Journey 3 = 18mls, Turbo, generally riding at 35km/h
Journey 4 = 18mls, Turbo, generally riding at 35km/h
Journey 5 = Error occurred after 0.1mile

As you can see I set the max speed at 35km/h as per SpeedBox advice. On each occasion I let the countdown timer run at the end of the ride. Before I reinstall the SpeedBox 1.1, I want to see if there are other riders with a Bosch Smart System, with the same software version and the same SpeedBox product (or a different tuning device) that have successfully avoided an error for longer than me. If so, I'd be interested in what steps you are taking, or how your rides vary from mine.

Thanks!

 

[TrekPwrfly]

I've done 700 miles
. Normally between 17 - 21 mph depends on the winds sometimes push it to 25

Hi Embt: from all the research I've done, you seem to be having the most success with a derestricted Bosch Smart System. Could you PM me as I'd like to find out a bit more details about the speed settings, types of rides etc. I have a SpeedBox 1.1, but I'm beginning to think that the VolSpeed might actually be less detectable based on your experience

Haven't had the bike delivered yet so it'll be a while before I can give feedback.

I installed the bikespeed RS last night on my bike.

Delivery was quick from Germany but I had to pay an extra £36 for the import duty. So total price was around £210.

Very simple to install. Could do it in 10 mins now I've done it once. Just need to work out wire routing from the spoke magnet into the motor.

Had a scare when I first turned the bike on as it wouldn't register the motor - but I left it for a bit and after trying various fixes - (starting the bike with a bit of pedal / holding the power and mode buttons for 8 secs) it kicked into life and is operable whilst riding using the combo keys to turn it or off using my mode selector.

Now it just works immediately when I turn the bike on so hopefully won't have to worry about that issue again.

Took it for a ride and it worked perfectly. Need to properly test it later this afternoon but the difference is amazing from stock. The feeling of not riding into treacle at 15mph is so good...

I'll give more feedback later but for now it seems like an excellent solution - especially with the algorithm beating software (lets see if it actually works as promised).

I have got the Bosch Flow app and have tuned the motor in different modes but haven't signed up for an actual account or registered my bike so I'm hopeful I can still use the Flow app functions without causing issues, but if necessary I will just limit network access on the app or just disconnect from any data whilst using it.

I'll try that after using the bike for a while as my modes are all working as I want anyway so theres not really any reason to mess with it for now.

If someone has a magnet on the rim and the manufacturer does not want to agree to change the configuration to move the magnet to the brake disc, the best option in my opinion is to change the software to the US
then we have a speed of up to 32 km/h the display shows the correct speed, and it is not detectable because it is the factory software from Bosch

Let us know when you've done that.

I'll have the New Zealand software on mine please...

What is the top speed of the ebike in New Zealand?

So how fast can you go on an E-Bike? New Zealand supports E-Bikes with motors of a maximum sustained power output of 250 watts and a maximum speed of 32km/h for off-road models, and of up to 45km/h for models designed for road use. So can it go faster than the motor supports? Yes, it can.

I live in Poland and here we have a support limit of 25km/h After changing the software to the US, I have a limit of 32km/h (screenshot from the application in the attachment) I changed the software in a bike shop. I looked for a shop that sells bikes with a 32 km/h limit and asked them to change the software on my bike. They did it on the spot in 5 minutes

 

[martyfrommonmouth]

The Bosch website states the Performance Line Speed goes 45kmh. I wish we would have simple options to unlock that speed. Its annoying. Cars or motorbikes can go faster than the Speed Limit but the motors are not soft locked to the legal limit of 70mph. I don't know why ebikes motors are treated differently.

Anyway my chip works well so far so not too much of an issue.
