A Japanese hobbyist has built a robot cyclist. The video is quite amazing to watch.
The robot is much smaller than human size and this will account in part for the sometimes erratic and wobbly ride. But it's an impressive achievement. It's not the first time a robotic cyclist has been built, but as far as I know this is the smallest.
One day, no model railway will be complete with tiny robotic pedestrians, cyclists and road vehicles moving around the tiny landscape. Now there's a thought!
