We think that if our young ones are old enough to walk and scurry around they’re old enough to start balancing on a bike and that’s where the Siren 20 in Single Speed Bike comes into play. GT utilizes its LegitFit system to ensure little riders’ bikes have the specs they need to make riding easier and more fun. To start the Q-factor of the Siren 20 matches the hip widths of kids to keep feet on the pedals and more power when riding. A lower starting gear makes take-off easier by slowing down the speed to build up to where they want to be and the bottom bracket is placed in a forward position to improve pedaling. Last kids will benefit from an updated geometry that makes for comfortable standing while straddling their bikes. The result is a bike with enhanced stability and comfort to improve confidence for kids learning to ride.
