Hello, I recently purchased form what I can tell an Electra or APC mini chopper. Has dual rear wheels and appears the 43 cc Engine. Picked up at a Garage Sale not running. Have it running and it is running well and have been able to find quite a few parts online. What I have not figured out is where the battery goes. It was hanging by the wires off the side of the bike when I purchased. Any information or leads to an assembly manual would be greatly appreciated. Already can tell this is going to be an enjoyable hobby. Thank You.
