Are SAVA / SAVADECK bikes reliable?

Discussion on r/whichbike and r/cycling characterizes SAVA frames as structurally fine and the 15-year frame warranty as legitimate, but flags that some buyers gradually replace contact points (bars, saddle, wheels). bikelabhq.com's long-form review reached a similar conclusion: strong spec sheet for the price, with minor quality-control issues. Buying assembled by a local shop is widely recommended.
