So with the new Bosch Nyon system now on our shelves for 2015, a lot of customers are asking if the new Bosch Nyon system can be retro fitted to their existing electric bike? E-bikeshop explains.. We have been testing the new Bosch Nyon satellite navigation advanced display for some time at e-bikeshop.co.uk. Its certainly a revelation in the eBike world, with features like smart phone integration, fitness tracker & sat nav mapping. We have the full article of Nyon features here. Many have been asking if this system can be retro fitted to their existing Bosch eBike? Well today we reveal all, as we manage to reverse fit the custom head unit onto a Haibike that comes as standard with the Bosch Performance Intuvia controls. So it can be done with some Bosch experience!
Does Nyon work on all Bosch eBikes?Yes: Nyon will now work with both Active and Performance Line eBikes from 2014 onwards. You can tell what Bosch motor you have by checking the model year first. Most 2014 bikes come fitted with the later Bosch 250w motor. Nyon is not currently compatible with S Pedelec 350w Motor versions.
How did we upgrade to Nyon?
Firstly we need a 'donor' Bosch electric bike, to perform the upgrade on, we chose the Haibike NDURO PRO 2014 model that comes equipped with the Bosch Intuvia display as standard.
Then, the easy bit, we fit a new Nyon head unit display and control buttons by taking off the old controls and installing the new control buttons with the little navigation thumb control on board and Nyon LCD display.
Once fitted when you turn the Nyon head unit on; the Bosch system will immediately flash up with an error code. Error 414: 'This eBike is not equipped for the use of Nyon". You cannot operate any of the functions when the system is in this state.
Now the difficult bit, we connect to our in house Bosch diagnostics computer and fool the diagnostics into thinking the electric bike comes as standard with Nyon. We can't go into too much detail here but it involves many software remaps to ascertain the correct functionality & container file.
The photo above shows the programming in progress once we have the correct software map in place. Once done we can unplug the system, re start it & Voila! We have a working Nyon system on our 2014 Haibike. We have tested this and all functions can be used as new.
We can also save the old container file in case you ever want to go back to the original Intuvia display. We can flash the original software back onto the eBike without any problem.
