The GT Siren Kids Bike combines style, comfort and reliability to form a high-quality kids bike which is great for the developing rider. GT's LegitFit Design gives kids bikes the best fit with better positioning and easy pedalling on the lightweight alloy frame. The tough alloy frame is great for a kids bike as it is much lighter than comparable bikes with steel frames so that your kids can ride with control and learn how to handle their bike properly, without struggling to steer a heavy bike. Add to that the alloy rims, stem and seatpost which together form a durable yet lightweight bike which is tough enough to handle rough kids or a few of the bumps that come with learning to ride. The Siren rolls on 20" tyres with the ideal blend of grip and control for safe riding, while the V-Brake allows them to control their speed and ride safely. The GT Siren Kids Bike sets the bar high for kids bikes, made from reliable parts that are safe an will allow your kids to have heaps of fun on their brand new bike.

Features

  • Improved Geometry bikes with the LegitFit system feature geometry adjustments to improve ergonomics for youth statures. The result: Increased stability, comfort and confidence for a wider range of riders.
  • Easier Pedaling bikes with the LegitFit system have their pedal positions moved slightly forward. The result: Makes it easier to pedal. 
  • Better Positioning bikes with the LegitFit system have narrower crank and pedal positions that match the width of a child’s hips. The result: A stronger, more natural pedal stroke.
