Speedfit is a human-powered mobile treadmill invented by Olympic medalist Alex Astilean. Much like Fred Flintstone’s old rod, it uses people power to get it moving. The only real difference is that Fred’s feet no longer have to meet the road.
The version in the video is a one or two person model, but Alex wants to create a public transportation version of the treadmobile that will allow a large crowd to power their own mass transit. Sure, it looks silly, but I’m guessing it’s a hell of a workout.
