The Joy of Learning to Ride - A Simple Children's Bike
Different from the sporty NAIK series for young people, FUN 20 is simpler. Its lightweight aluminum frame is durable and the classic V brake is reliable. It does not have a complex transmission system, and beginner riders may prefer a simple bike that only requires braking.

Belt Drive - Maintenance-Free and Reliable
FUN 20 is equipped with a maintenance-free single-speed belt drive system, reducing the cost of learning to ride a bicycle for children. The 20-inch wheel size is suitable for the age range of beginner riders.
