Anyone ever replaced a CX Gen 2 for the new Gen 4

Thanks again for your work with the adaptors!
I had to put my project on hold during the winter - but now the temperature is rising and I have found some time to work on the egg-cover. I have still some work to do on the structure, but I am quite pleased by the result. I choose to integrate with the the cx4 bottom cover to protect the cables and make the design easier for myself (I can not draw - I am using OpenSCad).

I am excited to see the others here have made a 3d-model of the cx4 motor and making a cover from scratch. Keep up the good work!

Looks good!

Which brand are the bottom and left side cover? They seem like a good fit for this project!

I will plan make this from Alu plate laser cutted. Soon photos.

Very clean scan!

Also had an opportunity to work with cover design.

The right side of the engine was too complicated to deal with so I covered it completely. That's why the left side has a downward hole in the front for airflow. On the right side there is a slot to allow easier installation of spider bolts.

Sorry for the late response.... at first I did not know what to answer.... I got the bottom covers from my local bike shop, and they was the same as the covers on my Bulls Copperhead Evo 29 XXL bike. I thought they were generic Bosch as Bulls is not sold in Norway. My local bike shop tried to sell Bulls for many years ago, but Norway was a too small country for Bulls. But now my local shop is selling Kettler - which might be associated with Bulls one way or another (maybe someone here can verify?).

So Bulls/Kettler is my best answer until I visit my local shop so I can ask them.

Edit: Your cover is also a very nice work! I also can share my source when I have fixed a few problems. Trouble is I am using OpenSCad - and this project is so much trial-and-error so the source is really embarrassing ;-) But the winter is not over yet - it is snowing right now - so do not hold your breath while waiting for me.

Edit: typo
