20-Inch (5-8 yr. old)

The Siren Coaster 20-inch is a bike designed to make your little one feel like a big kid. A durable alloy frame and steel fork, paired with a rear coaster brake and rear V-Brake, make for years of enjoyment. Front and rear fenders and a kickstand add to the fun!

Multiple gears and front/rear hand brakes…the perfect 1st mountain bike! Kids have their own riding style, and it’s one that changes over time. GT has completely redesigned the Kids’ lineup with bikes that fit every size and type of rider. Each model has the same quality and durability you’ve come to expect with GT’s full-size rides. And by utilizing GT’s Legit Fit system across the range, these bikes are designed specifically for those growing shredders.

For little cruisers looking to pedal their way forward…and coaster brakes to make them stop! Sure, we had grunge in the 90's, but it was never this much fun. Channel your little rocker's energy into two wheels and get them gunning for a different kind of stage from an early age with a single-speed bike built just for riders who are growing up through the ranks. The LegitFit system gives them better positioning, easier pedaling, and a faster start to your next ride.
