There are literally millions of decent analog bike frames bouncing around in various corners of <your city here>. Getting one up and running, and strapping a seat to the front and back as you have done, would be about 10% the cost of a new e-bike, and maintenance would be negligible.
Plus, you get to eat whatever you want guilt-free!
I am dismayed at how much people spend on plastic coffee pods just to avoid making a proper coffee!
Before I got an ebike, I didn't have confidence of riding on the road proper- > now I know I won't be slowing down to 5 MPH on an uphill, with someone behind me honking incessantly or overtaking dangerously.
I installed nice bright lights powered from the central battery, mirrors and a horn. This makes a world of difference.
I'd like to point out that the carbon footprint of a used bike is a negative number and the out-of-pocket cost is laughably low. I love when people can reduce their emissions by replacing a car with something with much less impact like an e-bike, but those are the exceptions statistically speaking, and it also doesn't delete that car from existence but rather brings about more demand for mining and materials. Buying used e-bikes is also a fine option.
No need for ebikes but child seats should be used on reenforced frames such as what the Dutch call "Moederfiets", you can also use a 'Transportfiets' frame.
You are adding an extra 5 Kg to your front steering tube and another 20 kilos to your back cargo loader. That is not what most frames were designed for.
Secondly things like double leg kickstands and steering stem lock are really important to load kids in and out of seats safely, which again don't exist in 'normal' bikes.
My point is you don't need an ebike but you should definitely not be using an off the shelf thin frame to carry kids around everyday.
Yes, you shouldn't use a department store bike. I (mistakenly?) assumed this is obvious to this reading crowd.
You sound like you have never worked on a bike before. It is not difficult to add different kinds of kickstands to existing frames. I believe you are quite under-informed on bicycle capacities.

Doubly so if you're doing any hills with a passenger on board.
Sweat/stink is what they're avoiding.
