Frog Road 58 TdF 2023 - Kids Bike
For 2020 we have teamed up with A.S.O, organisers of the Tour de France™, to bring a splash of yellow to our range. This special edition Tour de France™, official licensed product has the same great features as the Frog main range, with the addition of the striking Tour de France™ yellow with black logos.
Frog Bikes were the obvious choice for a collaboration to develop a range of Tour de France™ kids’ bikes. We were impressed with the research and attention to detail that has gone into the lightweight bikes.
Frog Bikes also shares our values regarding our commitment to the future of cycling, children and the planet. We are looking forward to seeing lots of children riding around on the new range. Clément Monteil, A.S.O. Licensing
This 20-inch kids' Road Bike is best suited for children aged between 6 and 7 years old with an average inside leg of 58cm.
The smallest of our Road Bike range, with 20-inch wheels, the Frog Road 58 is perfect for younger children looking to experience a different style of riding. The frame has clearance to fit both slick road tyres and cyclocross tyres with more grip making it the bike of choice for young, multi-discipline racers!
Wheel Size: 20 inch
