Frog 52 20w 2023 - Kids Bike
Easy to ride and lots of fun, the Frog 52 kids bike is built around a lightweight aluminium alloy frame and kids friendly components. The smooth rolling 20 inch wheels are wrapped in hybrid tyres that are ideal for cycling on mixed surfaces while the 8 speed drivetrain gives them gears for riding uphill and down.
This Frog 52 kids bike is great for boys and girls, and comes with an aluminium frame that is light, stiff and strong - for all-round riding performance. The saddle height is easily adjustable so they can grow into the frame. Strong V-brakes provide all the stopping power they will need and are easy for little hands to use.
Take the whole family for a ride on cycle paths, to the park or on forest tracks with the versatile Frog 52.
