Retrofitting Kiox on Bosch gen 4 (system 2) motor
Posted by _WinterBoy_@reddit | ebikes | View on Reddit | 4 comments
Hi,
I bought retrofit kit for my ebike. I plan to do it myself as it should not be too hard but I have two questions before start:
1) At the moment I have installed Purion on my ebike (Haibike from 2021, gen4 Bosch 85nm, system 2 - not smart). I never did any update to motor. Do I need first to do update of the motor or it is not needed for Kiox to work? Maybe it would be useful but if it not mandatory I would postpone it and wait when I have more time to take bike to service.
2) I want to do it myself as I have enough mechanical knowledge (hobby level) to know what is needed to be done and how to do it so I planned to do it like this:
-Put bike on service stand
-Dismantle plastics around motor
-Unplug purion and remove wire from frame
-Insert Kiox wire and plug it back to same port where Purion was
Rest is straight forward (clamping display and controls to bar...).
Will this work? Or there is something that must be done in service with official Bosch equipment?
P.S.
Yes I bought correct version of Kiox for System2.

I did that retrofit myself when I originally asked this question. The bike was a 2021 Haibike FullSeven 8.
It was relatively easy overall. I just removed the old cables and routed the new ones through. The biggest issue for me was that I had to remove, or at least loosen, the motor so the cables could reach the ports.
I never regretted doing the retrofit because the display is much nicer than the Purion. In reality, though, the only real benefits are more data and Bluetooth connectivity for tracking and analysis. System 2 still cannot be updated through the phone.
I have since sold that bike and bought a new one with the Smart System, which is better in every way.

How long did it take u to drop the motor and rewire it inside the frame from the beginning till end? Also did u have to get it updated by the dealer later since u installed it or no?

If you have the right tools, by that I mean basic wrench attachments, or ideally a dedicated bike torque wrench with bits for all standard bolts and you are reasonably handy, you can probably do it in an hour or less.
In my case, there was nothing that required any special tools or knowledge, since everything was basically plug and play.
As I said, the biggest issue for me was loosening the motor, but only because I did not have the correct bit for my wrench. I did not remove it completely, just loosened it enough to pass the cable through.
I also lost quite a bit of time routing the cables and connectors through Haibike’s integrated cable channels.
And no, I did not update the bike before doing it.
I also destroyed Purion jacks while removing it as I was impatient and pulled too hard.
