Hi there
If it is a three wheeler and not a tadpole then it is called a delta trike.
The reason the one in the video rolls over is because the engine is high up between the driver and the front wheel both recipes for disaster in this trike.
Vigillante and Trivette (Trivette II)
This is how to do it well !
This out corners a F1 car !
Welcome to the home of the VIGILLANTE
