Hi everyone,
I'm a mechanical engineer, but completely new to e-biking.
I recently purchased a Turbo Como 5.0 with Gates Carbon Drive. It came with 50 tooth front sprocket, but felt like the bike was geared too low and figured I'd change the sprocket to 60 tooth. Unfortunately the 60 has 5-spoke and 130BCD, while the original 50 has 4-spoke and 104BCD. See the picture below where I'm holding the 60 tooth in front of the 50.
I found, and then purchased an adapter from Ti Cycles:

I think for some applications this adapter would be perfect as they designed it, but I had to modify both the adapter and sprocket to get it to work perfectly. It was a little bit tricky, but I figured it out. Below is a picture of the bike with the 60-tooth sprocket installed.
As I mentioned, it was a little bit tricky. Since the information about this isn't available anywhere, I decided to make a video that discusses all of the issues and what I had to do to fully implement it. You can see the video here:
Let me know if you have any questions about this. I'd bet curious to hear what you experienced folks think of this.
Best regards,
William Benner

104mm to 130mm BCD Adapter — TI CYCLES FABRICATION
104mm to 130mm BCD ADAPTER This one was a tough nut to crack! Ideal for pairing larger 130BCD Gates Carbon Drive rings with wider 104BCD cranks for optimal performance on Rohloff Speedhub's outboard drive line. * Available as adapter only or as adapter with 7-piece SS chainring bolt set.
