The Yuma is a juvenile gravity bike, which is especially tailored to the characteristics and needs of riders with a body height taller than 1.30m and the respective low body weight. Delivered with 24″ wheels, the Yuma can be converted to 26″ wheels using the “Grown Up” kit, which is available separately.
The frame size is an essential part of the bike performance and above all of the riding fun. Select your required frame size from the table. If you stand between two sizes, then you only have to decide whether you like it playful or smooth running. For smooth running choose the larger frame size, for playful the smaller.
