Cubes are generally some of the best value Bosch bikes.
Tredz is one retailer, there are others.
They have a selection of 500wh Cubes.
You keep on asking the same question, but your requirement is power hungry and there is no magic wand for that.
For your proposed use you want a bike with the biggest 625wh battery which are less common, which equals more money, or a dual battery bike which is more common but still lots of money.
Riese and Muller offer several bikes with the option of a dual battery.
