Any electrically assisted bike gives you the feeling of having borrowed a professional cyclist's legs. It does not, however, do all the work for you. It is an assistance only. You still get a work out as myself and many here will attest, especially when hill climbing is invovled.
Adding a kit to a bike will inevitably increase the weight. My own avatar bike weighs in at atound 27/8Kg. Yet I cycle the hills of West Wales in my 70's. I do cycle without power - downhill or with the wind on my back on the flat. But I know that when I turn the power off It feels like cycling through treacle, it's not an enjoyable experience.
I feel you need to adjust your expectations before you spend hard earned money to do something that doesn't work for you.
I would not worry about the extra weight of a kit, it's assistance will overcome that extra. Having an assisted bike is not 'cheating', you will still be working and arrive at your destination with less emissions than the car driver who accuses you of such, but less sweaty!.
In order to get you and your kids up a steep hill without bursting your lungs or legs, you need a high torque motor backed by a quality battery.
Just one other thing. Check the Spanish regulations. We know, from a previous forum member, that Spanish police are strict. I know that means:
No throttle
No assitance above 27kph
When pedals stop turning assist must stop.
There may be other subleties I'm not aware of.
