Lately I’ve been planning the battery boxes (cardboard mockups) and the motor adapter plate, so that I could get them manufactured as soon as possible. It seems that I can fit the batteries pretty tight inside. The larger of the two boxes will be just as wide as the gas tank. While fitting, only some small adjustments came into mind, including beveled edges to the rear corners of the larger battery box, so that the corners won’t hit my knees. By shuffling couple of the cells around it was easy to accomplish.
The whole engine compartment (except the motor) will be hidden behind fiberglass fairings, so the ugly boxes won’t be visible after the bike is finished.
