I wish i could also move more people with me on the bicycle
Depending on the size of those people: bike child seat, bike trailer, or they can ride their own bicycle. Cargo bikes can easily carry two kids or one adult without even using a trailer.
It would also be great if there was some sort of heater/AC in it as well
That is called “dress for the weather”. Even snowflake pinko commies like me can do it.
