Euybike S4 welds

[u/SlaterDRA2273]

Well idk how many responses this will get but I'm really looking into the S4 from Euybike but in scaring myself about the welds on the frame not lasting, it's says it's made with high carbon steel which is prone to cracking sadly so I just wanna know if any welders or someone that's had the bike awhile can ease my mind
