Thanks for that, helpful. Yes, so I am using a carbon gravel bike. So 24kg, me at 75kg, tailer ~10kg. Perhaps on 15% I will be on a limit around 50kg. I do think I need to gear down a bit. The issue is the hill is curved, so you can't get a great run up and keep pace, you have to slow and navigate.
We will find out. I need to carry a 70kg washing machine next week, so that will be a good test.

In my mind a 70kg washing machine will be no issue for the motor, but it does depend on the gear range whether you'll be able to use it to it's potential.

I used to work for Pedal me, the bikes have a mixture of Bosch Gen2 CX and Gen4 Cargo. Although I think at this point they were all Gen2 CX..
During lockdown they were doing a lot of deliveries for food banks.
When fully loaded there were some hills that were literally impossible to get up, you had to go around. I'd say we effectively hit the limit of what the motor would assist. We couldn't gear any easier as it would risk breaking the rohloff hubs (and voiding warranty). Shame I can't tell you which hills... but with this sort of weight they wouldn't have to be very steep.
The bike unloaded is 60kg, the (stupidly heavy!) trailer was about 100kg, rider could be around 80kg and the food boxes were 5-15kg each. Hopefully this gives you a rough idea of where the limits start to appear.
