The ultralight Author Record 20 kids bike is suitable for children aged around 4–6 years and 115–135 cm tall. Its design focused entirely on reducing weight while keeping a reasonable price. All key components such as the frame, fork, handlebars and seatpost are made of lightweight aluminium. Exceptional in this bike category are the folding Kevlar Kenda tyres, which contribute to the excellent low overall weight. Add to that a 7-speed Shimano rear derailleur with RevoShift twist shifting. The specs of this bike make it suitable even for those who want to experience the atmosphere of increasingly popular kids races. As usual, there are 2 colour variants for girls and boys. If you have a small ambitious racer at home who dreams of one day becoming a world champion or Olympic winner, this bike will be great for the start of a stellar career.
