Jblackbrn., thanks for the detailed response!  After a frustrating repair attempt with the shop it looks like I?ll be attempting it if I can find the wire.  If not I?ll be buying the wheel as well.  Hoping I?ll learn a bit about it it the process.  My kid is pretty rough on the bike so I?ll need to get good at it! 

Not sure if I?ve got the same motor as you since mine is the rad runner.  But I?ll have to figure that out

I?ll report back for others if I get it done!

Thanks again

Jblacburn, I need to do the same.

Where did you find the motor cable?  Curious how this repair worked out for you!

Thank you
Brad
