The front side of the vehicle is using a mono-cycle while the rear part is using a skateboard. There is no pedal to push if you want to move forward. You have to manually push it forward like mini scooter. However, instead of front steering like mini scooter, this Sbyke is using a new rear-steering method to move around.
You can find the details with video over here.
