Rear child seat on an alu. frame

Hi all

I have a rear child seat:
https://www.bellelli.com/index.cfm?me...d=35&classe=13
https://www.nolimitbike.hu/img/kieges...OX%20LEVER.jpg

My current bike is an old broken piece of junk and i want to buy a new one.
Now i have found steel and alu framed bikes (probably the steel ones use low grade steel).
Regarding fixing this seat on the frame, steel has no problem.
The part of the frame where the seat mount goes is mostly stressed in compression and adding a little bending does not matter.
But what about aluminum ? Won't it break or fissure or something ? Maybe not immediately but in the medium/long run.
My godfather says he doesn't trust aluminum in this role. Is he right ?

The thing is, the bike i like best is alu frame.

PS
The bike tracks around here are in pretty bad shape (holes & co) so this might count somewhat.

I have put 100s of miles over the last 3 years on a 10+ year old aluminum mountain bike with a child seat. The bike was also my primary mtb for a couple of years. Sometimes I even ride single track with the kid. Your father is a steel loving dinosaur, there are plenty of them around, and some will probably chime in on this thread, but don't let them worry you.

Bring your child seat with you to the bike shop, and see what they have on offer..

step thru frame, is easier to mount once there is a kid back there..

Aluminum frames will be fine for the short period of time the kid rides the seat,
then take the seat off, removing that strain. Main bike shop brands the quality is fine..

people like lighter bikes, aluminum frames offer lower weight, at reasonable prices.

they do grow fast, children..

The aluminum will be fine. I rode my daughter around in a child seat on mine with no issues and I was weighing in @ 270ish at the time. When she outgrew the seat, I attached a trail-a-bike to the aluminum seat post and never had any issues.

That aluminum frame is still one of my favorite bikes. I trust it just as much as any of my other bikes.

Find a better seat that doesn't clamp onto the frame. Those Bell seats are notorious for slipping.

Hahaha! Very sage statement, fietsbob!

No, the child seat/aluminum thing should not be a factor in the "Which bike?" decision at all. Any frame can handle riding around a kid for 4 years or so. Like fietsbob said, choose based on other factors, like ease of use, accoutrements, and of course, color!

Thanks all for your feedback.
My intuition was that aluminum would be just fine.
The choice of bikes is limited for me especially since cost and type of bike is an issue.
After i've mounted the seat on the current bike i realized i actually need a lady bike ... go figure
I ain't that tall/long to get my leg over the seat+child.
So i'm basically down to one steel vs. one aluminum.
The steel one i don't like and it's pricier and the aluminum one is on my taste and it's lighter on my hands and on my pocket.

Allrighty then, it seems we have a winner.

Happy riding folks.

J.Do, you may be aware of, or have considered, alternatives to a rear mounted seat, but it sounds like you're really not too keen on a "woman's frame" or Mixte type bike, so I'd point out there are front mounted seats like the iBert (https://www.cambriabike.com/shopexd.a...FeUBQAod7FamDA) and mid-mounts like the Wee Ride Kangaroo (https://www.weeride.com/Kangaroo-Cent...icycle-Carrier) that may be of interest to you.
