TWO TINY WHEELS KEEP NEW BICYCLE UPRIGHT
A four-wheeled bicycle which recently made its appearance in Germany may be mounted easily, even by a beginner, and may be parked anywhere. Two small auxiliary wheels are attached by movable brackets to the frame of the cycle and are raised or lowered by moving a lever on the handle bar. So long as these wheels remain lowered, the cycle stands upright as shown above. When in motion, they are raised.
