Aggressor 20" Complete Kids' Bike - 2015

The GT Aggressor 20in Boy's Bike is that perfect step between training wheels and his first big kid (or small adult) bike. A great selection of parts, a very manageable size, and low weight make it a fantastic first two-wheeled machine.

The Aggressor's frame is a big deal here, and by big we mean just right size-wise. Two significant details make it seriously great for small riders. First is the geometry of it, that's shaped precisely to accommodate growing young cyclists without intimidating them. Little riders will immediately feel comfortably in control of the bike, thanks to a very low standover height (so they don't have to stand on their toes to stabilize the bike when not rolling) and a low head tube. The second big factor is GT's use of super light and super strong 6061-T6 aluminum alloy. It's the same top-notch stuff used on high-end adult road and mountain bikes. It's true that it might be a bit overkill for a kid's machine, but developing riders will surely appreciate the fact that the thing is so light, maneuverable, and tough.

The Aggressor's parts are also great for budding cyclists. A 7-speed drivetrain is controlled by a grip-style shifter up front that's quick and easy to master. Linear-pull brakes are easily powerful enough to quickly shed speed, but they're easy to modulate and not grabby. Down below, a durable combination of tough wheels and puncture-resistant tires keeps them rolling without worry.

The GT Aggressor 20in Boy's Bike comes in only one size, and in the colors Gloss Black or Gloss Red. The bike is sized for kids between the approximate heights of 4'0" (122cm) and 4'7" (140cm). Please note that the bike comes almost fully built but needs some minor assembly and tuning out of the box, so we strongly recommend visiting a trusted local bike shop to give it a once-over before riding.
