• Warning!!

    Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.

    Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.

Has anyone used the new Furious Evo chip with rim magnet on the new Bosch gen 5 ?
E Biketuner supply them and say 100% success rate so far ….?

For how many installs? What they say might be the case but they're unlikely to say otherwise, are they?
Hence my post buddy, I would also think there must be some truth to it as otherwise there just asking for a hiding for nothing….. hopefully someone will be able to give some clarification

The last week I tried to install the kit eplus Bosch gen 5,but unfortunately I didn't because the sensor that install near the motor touch in the frame and not possible to install the motor in the frame.

Sorry for my English guys.

Any updates on Bosch Gen5? Anyone having any success?
Obviously it's still 'early days' but we have a very high success rate with these kits across the Gen4, Gen5 and SX motors.
One thing I will say is these aren't a plug & ride install. I definitely recommend watching one of the install videos on youtube & the reading the instructions before placing an order.
What we've found is that any issues with them are usually down to the position of either the wired speed sensor or the electromagnet module. These are all easily resolved through troubleshooting though.
Unfortunately I can confirm that the Mondraker Crafty Carbon 2025 is not compatible. This is due to the design of the Carbon frame. We've not had any other installation issues with other brands though.
We do have a dedicated spot on our website for all things Bosch Rim Magnet, feel free to send us a message if you have any questions about these.

Unfortunately the Carbon frame on these prevent the Speedfun kit from being installed properly. There's just not enough space to attach the electromagnet and refit the motor. The latest Cube's, Haibike's and Pivot's all seem to have more room making the install a bit easier.

Think the same on the cube hybrid 0ne77,tbh don’t want a spoke magnet either.
Yeah - I don't either but there aren't any other solutions currently. My bikespeed works fine on my Gen 5 CX but the weak point is the spoke magnet - they are sh!t! Need a better solution or a better way to fit a magnet rather relying on 1 screw to hold it against the spoke....

Choose the version you want by going through the questions - I went for the RS version - I didn't need the customisation of the RSc - you can also get a screen that works with it but I didn't get that either.

The issues I've had with it are related to the speed sensor and spoke magnet - you need to get them really close and you need to make sure they don't move.

I'm looking for a solution for the spoke magnet that is better than the one screw that holds it to the spoke. I've found some 3D printed spoke magnet holders that look like they might work - I'm sure there's something out there because the current spoke magnet on a downhill bike isn't great.

I'd somehow accidentally posted my question about these Bosch de-restriction methods in a different thread on a bike that uses this motor. Another user was kind enough to reply to my non-sequitur, and told me that Bosch dealers can see any messing about with things, so the answer to my question is that it's irreversible, but I just wanted to double check with the peeps in this thread:
Do any of you guys know how reversable these mods are? These derestriction kits are very intriguing, but if you have a motor failure (which can happen from time to time regardless of mods) and it's still within the warranty period, can you reverse everything to avoid raising any eyebrows in the warranty process?

The Bosch dealer can see that the motor or sensor had errors.

They cannot prove it was because you installed a device.

The motors throw errors all the time. For example, if you removed the rim magnet you will immediately get an error. This is a generic 523001 error that tells Bosch there's an issue with the sensor. It can't see what actions you did to make that error happen.

As you are modifying hardware not software (unlike remapping a car which on Bosch ECU shows a yellow warning that cannot be removed because the ECU software has been changed from stock), you have generic error codes that can be caused by different hardware factors.

You can fully remove the hardware derestricting device and return the motor to stock with no signs it ever had a device installed.

Even 524 errors cannot be proven to be your fault.

The only way you will get warranty denied is if you say 'yes, I had a derestricting device installed'.

Anyway saying all that, it's still at your risk and it is inconvenient having to visit a Bosch authorised repair centre if you get 524 error.

Oh man they delivered to me! Weird.
Man, I'm getting close to giving up with this speed sensor issue.

I thought I'd solved it, went to the woods. It triggered 523001 again.

It's really getting annoying now.

I'm seriously considering going back to stock and selling this bike and saving for an Amflow as I cannot be bothered working around this Bosch motor.

It's ridiculous.

Not quite true, Considering the 524001 is a manipulation error which obviously means desrestriction has been tried.


I know for a fact the Bosch dealer tool can identify derestriction even if you never trigger an error (seen this at my LBS Trek/Bosch dealer). Derestriction can possibly = no warranty, end of story.
