Hedstrom Power Ped Electro Drive

This children's bicycle has been in storage for many years. I believe it is of 1980,s vintage. It is battery powered and the right side handlebar lever controls the speed. The brake is a "suicide pedal" mounted on the left side of the central frame member. The wheels are solid rubber and the seat, the front fairing, front fender and the battery / motor housing are all flexible plastic. The battery and motor are housed within the large unit under the seat. Access to the battery is via the rectangular red snap out cover.
I have been researching this bicycle on line but have been unsuccessful thus far. It would be nice to have some history on the bike and possibly Hedstrom literature such as directions, promotional info etc.
If anyone can help steer my efforts it would be greatly appreciated.
Thanks,
Kevin
