GT's Aggressor 24 has the same features as adult mountain bikes, scaled down for kids. This pint-size rig is loaded with GT's great-handling 6061-aluminum frame, a bump-absorbing suspension fork, a quick-shifting 21-speed drivetrain and light aluminum 24-inch wheels with knobby tires. Now that they have all the tools necessary to tame terrain on and off road, they might just be faster than you.
