Today i have ridden about 20 minutes. I have learned a few new things. first of all I can get about 2 full revs in going backwards at a slow rate of speed. second I learned to mount by starting on the side and wrapping my leg around the front and to the other pedal. third I can Jump mount indefinately, with or with out hands. I have not landed a single unispin today. I also hopped up a mini set of brick stairs. each stair is about 2" higher than the last. one by one, or the whole stair case, all togather its about 6-8" high in total.
