1946 Socovel Electric

Here's an electric motorcycle made in Belgium during WW2. The large box contains three 12 volt batteries which supplied, according to the article in the November 1989 issue of the Classic MotorCycle, a 48 volt motor located in front of the rear wheel. Lighting came from a 6 volt tap on one of the batteries. I know, the numbers aren't adding up.

Top speed was 15-20 mph and range was a short 25-30 miles. The company apparently made at least a thousand of them, but as the war ended and as soon as gas became more plentiful, the company stopped production.
