GT has developed a new line of kids’ bikes that utilize its Legit Fit system and are designed specifically for those growing shredders. The Legit Fit system enables GT to build kids’ bikes that have narrower cranks, proper gearing and improved body positioning. All with the benefit to optimize pedaling, balance and speed right from the start. And it’s a system that works for kids of all more needing to “grow into” a bike.
