Bicycles intended for teenagers with 24” wheels have all the characteristics of an adult bicycle - the design is no longer so childish, it has internal or external gear switching mechanisms, and there is no longer the possibility to add support wheels. So it’s a great option when the existing bicycle is already too small, but the adult bicycle is still too big to ride comfortably. Most suitable for height between 125 and 150 cm. The teen bicycle manufacturers that we offer are Unibicycle, Merida, and Romet.
