A new Fiberglass Battery Box is planned for the Type Eleven. The LED Lights on the Type Ten are a complete success, and the bike received many thumbs up and compliments at the Car Show last Thursday night.
The location of the new battery box is shown in the embedded video (above). This should be an ideal location on account the center of gravity will be kept low.

Has anyone installed a battery box in this location before? It will be mounted on a fiberglass keel hanging from the downtube.

I will keep you all posted .
