Re: Motorized Bicycle Take a Tip...Leave a Tip
i'm with aleman on this. spoked wheels work because they flex. that's why soldering or ziptie-ing the crosses doesn't work, and that's why your idea won't work.
the JB weld would more than likely break up just from the wheel's natural tendency to flex, and then your innertube would have something to rub on and go flat.
if the JB weld actually held, then you wouldn't be able to true the wheel in the future, replace any damaged spokes, or re-lace in a new hub without having to clean up the mess.
if you want a solid wheel, get a solid wheel, like a mag wheel or something.
