The custom ride mode is a software/app module that must be purchased at minimal cost using the installed bosch app on your phone. The other is the topographical range calculator which shows your your range on a map based on topography, less range into the mountains, more across the flat river valleys.
Although I do have the custom ride modes loaded into my Nyon and can adjust them on my ebike connect portal on my PC, I really do not use them as I find the pre-loaded modes to be more than adequate. I guess I need to learn more about how they might be used for specific rides.
I think you can set it up to give you a quick boost at lower speed to accomplish what you want. I already find that, at least on my CX bikes, it gets me across the intersection at least as fast if not quicker than the cars.
