The 2021 GT Grunge 20 is a kids bike for the up and coming rider. This model is starting to get some similar features to adult bikes, with an alloy frame designed using the LegitFit system which provides better positioning, easier pedaling, and a faster start to your next ride. While you’ll also get a range of durable alloy components, such as stem, seat post and rims. When your kids are flying around and having a great time on their bike, they’ll need to be able to stop at any moment. For this reason it is equipped with coaster brakes, for the perfect amount of braking power for the little ones, so that they can be kept safe and sound. This bike offers reliability, durability and good looks in one package, perfect for a younger rider.
