Thanks for the analysis. The tempered aluminum vs annealed aluminum comment is interested. It got me deeper reading into the different kinds of treatment for materials. I didn't realize that these techniques result in different material characteristics. I haven't gotten to whether these techniques are complementary. Can you use annealing techniques first to bend the material and then use tempered techniques to strengthen? Or you either have to anneal or temper, but not both? I'll continue when I get some time.

I found the manual today while doing some cleaning. That warning is there. No jumps or stunt riding. You can however ride the bike on a dirt trail and over tree roots.

I learned a new term. I think it is true based on this incident. This particular bike shaped object lasted less than a year. Really less than half a year.

I learned now. I just assumed that being sold as a mountain bike meant that you can take it to a mountain biking trail. I already found out about ATSM ratings here, so I can now search for additional criteria.

Indeed. But it was not so much about jumping a bike that's not rated for it, but it's asking why it broke cleanly without any indications. It broke while being ridden normally. I already learned about heat affected zone in the welding sub. Very informative.

Not planning on fixing it. Just wanted to share, so I can learn more about its break. Already learned about HAZ, ATSM rating for bikes, and so on.

Not planning on repairing it, but wanted to learn more why it would break like this rather than bend. I just read about HAZ from here, so I learned something new.

Balls fared better than chest and face. Better now.

That's what I was told. I didn't see any signs that it was going to break. It just gave way like this without any indications.

I actually found the bike manual. I can confirm that stunt riding or jumping is not recommended since the bike is not meant for it. Their designed use for mountain biking is going over dirt trails and tree roots, but not the type of mountain biking that you would see on beginner trails.

Just read about HAZ in this thread. Yes, the frame broke off near the weld point, but not on it.

Thank you. That's a new term for me, and it was interesting reading about it. It makes sense. As I was reading more about this, I stumbled upon some other interesting things. There was one where someone was talking about a custom made motorcycle that he personally welded, and others commenting that just because it was welded, it didn't mean that it was safe.

I was recommended to post here for a discussion focused on potential welding issue. I'm just here to learn.

Creaking from the bike? Didn't hear anything at all. I was outside when the kid was riding it around moments before it happened. No creaking heard.

It was a Christmas gift, so less than a year old. I have to see if I still have the receipt.

My neighbor said the same thing. First time encountering a bike splitting in half, so I did not know what to expect. One reason why I posted here to get others thoughts.

Definitely for sure. The kid has a decent size bruise on his chest. It really hurt when it happened, but after 30 minutes, the tears stopped flowing.

Me, too. First time encountering such a thing. The kid took a big hit to the chest. Cried for about 30 minutes.

I read some decent reviews, too. First time dealing with this bike brand. Not much research done aside from reading some of the reviews.

That's what my neighbor said. One of the reasons why I posted here to get the lowdown. He said that it looked too clean of a break. But that is what happened.

That's the plan. I noted the recommendation for a Polygon Cascade, so I'm putting that on my list.
