>From previous letters we traced the origin of the 2-wheeler
to Jack Halpern. He picked up the idea from somebody else
(anybody knows who) built a 2-wheeler and mastered it.
The Kick-up mount was thought up by the same Jack
Halpern, who had problems with it. He discussed it with
Daniel Dumeng who was able to do it with minor adjustments.
Jack then mastered it the same date.
Hopping on wheel was usually entered from the floor or by
jumping from the pedals while turning the unicycle 90
degrees. Before UNICON IV, Javier & Ernesto Ruiz developped
a new entry. When they jumped from the pedals they turned
the unicycle 270 degrees on the ending on hopping on the
wheel. They showed that trick on tandem on their pair
routines. Javier & Ernesto were then 14 & 15 years old
respectively .
