Can this be safely welded up? If so who would you get to do it in or near Nottingham?
I'm tempted to get this for my son who is rapidly outgrowing his 20 inch wheel bike.
Good idea/ bad idea?
Is the chainstay steel?
And the seat stay allo?
Either way seems like a lot for a completely broken frame.
Suitable for the skip only!
100% it will be aluminium so no chance of welding. And even it it were steal that break is far from clean.
Totally fixable but not worth it unless you know a fabrication place well enough to be paying under mate's rates.
No. Waste of money, will need more time and expertise than it's worth. Probably 6000 series heat treated and will need post weld heat treatment.
Or, bodge it with adhesive and carbon fibre wrap at home and keep an eye on it (I wouldn't ... )
Children grow so quickly (especially in your case!) it’s sometimes better to get a good quality new bike?
Saracen and Ridgeback have some excellent models, I wouldn’t bother with the extra weight and servicing complications of suspension yet.
That appears to be advertised as a working rear shock and front triangle "if required". Maybe a rear triangle could be obtained elsewhere (?).
Your son. No way.
Somebody else's son. Yeah absolutely!
I wouldn't attempt to repair that and I've been a welder since I left school (just over 30 years ago). Its definitely possible to but controlling the distortion and shrinkage will be extremely difficult without a proper jig to keep everything in place while its cooling down afterwards. Aluminium frame would also require heat treatment as the area around the welds ( heat affected zone) will be weaker than the rest of the frame and likely to crack
Oh well thanks for the advice. I'll give up on it 🥺

Yes exactly.

I did think about that, but had decided against it.

Thanks for the experienced answer.
