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-on the patented conversion system easily allows a parent 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.
