Combining the front end of a mountain bike with the back end of a kick scooter makes a high performance scooter that is easy to ride.
The high wheel shape (aka penny farthing) hearkens back to the 1880s when big wheels ruled the roads. They too were pursuing greater comfort and more speed.

Lessons learned: next time I will try to curve the down-tube closer to the wheel to try to bring the scooter body further forward. that has the effect of reducing the reach forward, distributing more weight onto the big front wheel and reducing the vehicle length by about 2-3".
