YBike Evolve 3 in 1 Trike Meet the new YBIKE Evolve 3 in 1 Trike developmental ride on. Designed for children between the ages of 2 and 5 the Evolve focuses on the early developmental skills for easy transition to a normal pedal bicycle. Unlike most combination ride-ons the patented conversion system easily allows parents to convert the Evolve from a classic style pedal trike to a balance bike with two rear wheels and no pedals and ultimately to a more advanced running bike with one rear wheel and no pedals. All of these versions are fun to ride and are critical in a child's physical development. Adjustable seat allows the Evolve to grow with the child.
