GT has developed a new line of kids’ bikes that utilise 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 benefits of optimising pedalling, balance, and speed right from the start. Even better is that it’s a system that works for kids of all ages, no more needing to “grow into” a bike.

It came with 2 left pedals though, so my boy couldn't ride it on the first day we got it, but other than that, very happy.
