Seriously, get it to a car repair place. They’ll have welding gear, and it’s only a bit of steel pipe, effectively. They could also possibly bung a little gusset on for extra strength.
I wouldn’t buy use a previously cracked bike. Failed frames could cost lives.
Bit overdramatic, no? I’ve ridden a frame that’s bin Araldited back together for over 3 years in the carnage that is That London.
And I din’t die. 😀
Even when it did fail, the pop rivets I had bunged in as a safety measure kept it from failing catastrophically.
I’ve seen some right bodged up stuff being ridden round for years. Get it welded up. Then just spray some primer on the weld, stop it rusting. If you use it as a hack bike, it won’t matter what it looks like really.
Or give it to me if you’re that fussy. Is it a small?
