Volare Gradient 20 inch children’s bicycle 6 speed. The Volare Gradient children’s bicycle range is of superior quality. The frame of this bike is made of ultra light aluminum. Also parts like the handlebars are made of aluminum. The different colored rims give the sleek design a special touch. In addition, the bike has an aluminum smart control system, which ensures that the handlebars are limited (not adjustable in height) and to reduce speed the bike has two handbrakes (one front and one rear brake). The handles are made of Kraton, a wonderfully soft rubber, which makes them more comfortable. For safety, the bike has reflectors on the front and back and with the bike bell you can let everyone know that you are coming around the corner. The 20 inch pneumatic tires make this bike suitable for boys between 6 and 8 years old with clothing size 116-122.
