Inventor Wayne Soohoo has been working years on a system that allows a tricycle to lean into turns. The leaning allows tricycles to go into turns at higher speeds with stability. Although it looks like there haven’t been many updates to his site for years, there is a treasure full of great information for anyone thinking of building their own leaning tricycle. Hopefully, someday we’ll see a mainstream leaning tricycle based on his designs. Keep up the great work Wayne!
