does anyone know where i can just buy a giant ebike frame from 2019 i have a hybrid and homistly want bigger tires i just want the frame so i can swap my electronics
I do not think Gaint will sell only a frame, but my best guess would be to ask a dealer directly. It seems at least possible, that a dealer, could sell a frame as a spare part.
With the current shortage of spares however, I doubt seriously you will have much luck.
