To be fair i don’t own any calipers and that is part of what is getting me into trouble. But i have now bought 2-3 hub mounts/adapters and 2 motor mounts both of which had to be returned for too big and too small. I guess my downtube is smaller than 1.65 inches, and its bigger than 1 inch. Same goes for the rear hub adapter. I can get more exact pics (using the string trick) when I get home to help anyone better understand. Is there any way i can use the disc brake hub adapter to connect a sprocket? I believe it has 6 screw holes. PICTURES HERE

I bought a proper 3 arm hub mount for the sprocket but i tested the fit of the sprocket while i am waiting and i see now that when i line the wheel up to where it needs to be, the caliper arm for the brake pushes the sprocket into the spokes. Should i just remove the rear brake? Maybe get front hydraulic?? I can keep the rear disc itself as a chain stop over the sprocket maybe?

I mentioned the stretch cruiser in general in another post and someone mentioned that if i used a v-mount for those chopper bikes like this one: https://a.co/d/07yk2eS3 That i would be safer and possibly welding it if modifying the baseplate of the mount was not sufficient. I was curious though after finding this weld in the seat post if that changes things because i was going to break the engine in on the stock kit mounts at the rear triangle but thats directly over the problematic weld 🕳. Luckily the company did mistakenly send me two frames and the second one is much better. I was only concerned because of the ai response (i know next to nothing about Automotive mechanics/engineering and would like to learn) stating that vibrations are what is the key killer of these bicycle frames when doing these builds and i would be dailying this bike about 31 minutes by pedal or 5 miles there and back everyday. The second frame was going to be my gal’s for an ebike but perhaps i should swap frames/projects.

My kill switch cables are too short for my stretch cruiser frame shown in picture. I don’t know where to find a way longer one or the right stuff to extend the connections.
