Bosch e-bike diagnostics and service report (2018 Performance CX)

Bosch e-bike diagnostics and service report (2018 Performance CX)

Here’s a look at the data that is logged by the Bosch motors. We did not perform a service of the motor, but I got to see the service checklist.

Thanks to Sykkelhjørnet (Drammen, Norway) for taking the time to alter the wheelsize and show me the dealer software.

  1. I have an Ebike with an BOSCH Active line plus I want to change the gears to a Rohloff Hub can I change the gear ratio to 1.3 to 6.8 with the service software that you are using?

  2. Surely altering wheel rolling circumference to match the fitted wheel only means the Purion then reads correctly and it doesn’t me the cut out speed was wrong, just that the speedo was inaccurate.

    Are there any entry level E-MTB you recommend that are for sale in Norway? Preferably around or under 20k NOK. I just moved here and am not familiar with many of the brands besides Trek, Giant, etc but would like to find something to start out with for trail riding and commuting. Thanks!

    I think this software should be available to the public. I like to put a 27.5 tire on the rear of my 29ers. It increases torque. Makes steep climbs easier, and the tailend lighter to kick around turns. I have a purion display. I cant alter wheel circumference, and the bike shop won’t.

  13. name of the Software?

  14. Do all Bosch service centers have the same screen view as you when doing a firmware update. Will it show the advantage of upgrading to the new firmware. A description/ text file telling what will change before installing the New firmware.

  15. Interesting content (i.e. getting inside view of software screens at bike shop), thanks for sharing!

    Hi, I have a Bosch Performance Line CX, and a few days ago it began to make a noise, mostly on emtb o turbo mode but only at climbing…. Similar to a coffee grinder. How can I know the kind of bearings or kit I need to replace? Thanks a lot
