I just upgraded my Cross Current to 1000W and even that isn’t quite enough to cruise at 28mph all the time (although it’s way better than the former 650-700W peak power.) I think 1200-1300W is what up I would need to realistically cruise at 28mph in most conditions.
Where did you get the information about reaching the cruising speed of 28mph with Bosch Performance Speed?
With just 350W the Bosch Motor reaches 28mph.
