While not showing fenders currently my drop bar bike has the capacity for them as well as a rear rack I just don't need those accessories. However it does meet your other criteria with a 780wh battery, two H2O Kingcages and a high gear ratio due to the 2spd internal bb gear that has the equivalent of a 60t chainring. I know it is DIY but sometimes that is the only way to get specific needs taken care of?

I Know going from 46 to 42 my mechanic didn't to find anything in the settings to change.According to Bosch small jumps are accounted for in the programming but large changes are discouraged and can cause damage/performance issues, at least that's what multiple service reps have said

After your change (albeit in the opposite direction) did you have any side effects? Error codes? Reduced range? Etc.

That is about right. The mfg. says 26 for the Tetrarack M2. But recall that it is designed for off road conditions with 26 pounds. For a commuter it will be fine.

nope I had a bit more range because I could put more torque in the the system.

I've never seen anyone post about getting errors after making a change, though it's probably 50/50 between folks doing it themselves vs having the dealer do it. I assume it has more to do with anything too far out of expected range can trigger a fault code, but Bosch has never explicitly said what the range is. It's probably in place to keep people from doing stupid things like put a 80T chainring on and move the speed sensor in to fool the system into allowing higher assist speeds.
Latest example is BikerG just posted last week about going from 42T to 36T. I'll probably swap my gen2 Speed from a 20T to 18T sometime this winter as I'm about ready for a drivetrain replacement.
