The design is similar to those children 3 wheel sliding scooters that you need to wiggle to move forward.
The thing I don't like about this design is that you cannot change your stance.
It would be very tiring to stand in the same position for a long period of time.
On a regular 2 wheel stand up scooter you can switch positions from time to time and swap the foot that is in front.
