Apologies if this has been covered previously, but I didn't see it if it had been, and at this point I'm at a loss.
For context, the bike in question is this year's Haro Double Peak Sport 29 https://harobikes.com/products/double-peak-29-sport-2021 I have recently completed(?) a conversion to electric power utilizing a rear hub motor kit purchased from a domestic retailer. A couple of days ago while on a ride it became necessary to stop to investigate the source of a sudden and clamorous racket, and... well, I was taken aback when I discovered this:
Where once there were braze ons, now
there are just gaping holes in my seat stays(?!)
Now... I think its relevant to point out that the only weight on said rack was the weight of the UPP hailong battery (less than 9 pounds). Clearly, any rack being marketed is rated to be capable of bearing a considerable amount beyond that (the Topeak UNI SUPER TOURIST DX (DISC) being no exception to this rule, itself (per Topeak website) boasting "MAX WEIGHT CAPACITY26 kg / 57 lb," So... I guess this raises quite a few questions-- was it... erm... the additional stress caused by vibrations(?)-- that doesn't make much sense to me. Was it simply absurdly sloppy welds? I'd like to think that's not the case either, but... am I correct in assuming that these Gaping maws
In my seat stays will continue to degrade if I endeavor to engage in the very activities one might be motivated to purchase an MTB for? Does there exist some product on the market that can correct or reinforce this unlikely circumstance? I've been unable to find it if it has, and this same line of inquiry gleans as many and varied responses as the number of local industry professionals I present it to...
Weld it again?? Is a hole weldable? It certainly doesn't predispose me to await whatever other potential hoodwinks
I'm sorely vexed to scrap it (having invested no small measure of time, effort and the extent of the meager resources I had at my disposal) and replacing it is quite beyond my means. And as if to add insult to my admittedly-merely-euphemistic (at this juncture) injury, I can't petition Haro for warranty as I purchased this contraption from a private seller subsequent to she having determined after its maiden voyage that it's frame was just too large for hers.
I've quickly come to rely on cycling as legitimately the only activity that restores me to some semblance of sanity in an otherwise antagonistic and hostile personal life circumstance, so... I guess I'm hoping to hear that I'm overstating the problem(?) 'it's really not something that constitutes a catastrophic failure; just slap some X____ in there and get back to it...'
