New bicycle made like the Flintstone's car

(Scroll down for video) Fred Flintstone is making a come back in real life with a new bike.

Several German designers have invented a bike without pedals or a seat, which requires the drivers to run in order to gain speed,
just as Fred and Barney do in the Flintstones cartoons.

"Fliz" is not a tribute to the family Stone Age cartoon. Rather, it honors the creators of the bike, Tom Hambrock and Juri Spetter, as they created a tricycle like this prior to the bike we all use today.

"The goal was to develop Fliz to bring a completely new driving experience for all," the two said on
their website.

Fliz is a reference to the German word "flitzen" which means to speed.

To drive it, users are pulled into a harness and then increase the speed by running. They cross their feet flat on the rear wheel.

The designers said Fliz should be seen as a new option to "overcrowding" in urban environments.

They have presented their invention to the annual James Dyson Award, an international student design award.
