I have a Giant Lite LA Free Electric Bicycle.
So where my down tube meets the bottom bracket (well what's actually the top of my engine), has snapped. Not cracked. SNAPPED. OFF. Right now I'm just dealing with getting all the plastic guards off the engine/frame, and taking the crank arm off. Afterwards, I have JB Weld epoxy putty. I don't know what the best way to use it is, or if it's the best thing to use at all. Any tips?
Also, when I actually get it permanently welded, will I have to take the whole engine off? I need help!!
