I have a 24 volt electric bicycle the motor is in the front hub the battery is a lithium ion 24 volt made by Panasonic. It doesn't have a throttle, it has what is called a (PEDAL ASSISTED THROTTLE) Make a long story short, I need a controll box for it and I was wondering if anyone knows who I could call to buy something like that. Any help would be greatly appreciated. Thank you.

I would double check to make sure it is the controller. If it is, get it fixed. Or, use a different controller that is compatible.

I'm assuming you tried the manufacturer, the bike shop that sold it, google...

How do you know it's the controller? If you're sure, there should be information that designates the manufacturer. Otherwise take pictures and post on endless sphere. C58, CK, Doc Wui & 350 are astute and may be able to help if you post a picture here. Also, there may be other replacements.
