KEY PERFORMANCE FACTORS

Here's a ticket to hit the trail. Giant calls the XtC Jr 24 the perfect way to introduce young riders to off-road riding.

Lightweight frame

ALUXX-grade aluminium frame provides a lightweight, purpose-built chassis for aspiring young off-road riders. Giant describes ALUXX as 6061 alloy with single-butted tubes.

Confidence and control

Size-specific 24-inch wheels and front suspension give young riders the performance they need for true off-road riding. The fork has 50mm of travel.

Kid-friendly features

Youth-specific performance components help young riders improve their off-road skills, including Giant Junior grips, a Giant Jr. Sports saddle and junior MTB brake levers.

Twist shifting with a wider gear range

Shimano REVOSHIFT is a twist shifter: kids change gear by twisting the grip with thumb and index finger, without taking their hands off the bar. The 14-34T cassette gives an easier climbing gear than the 14-28T on the XTC JR 20.

Who is it for?

Good fit: Kids 130–150 cm tall who want to try slopes and gravel paths beyond flat ground, and kids who are growing out of the 20-inch height range.

Less suitable: Kids under 130 cm should look at the 20-inch Giant XTC JR 20 (Giant recommends 120–140 cm). For mostly flat riding without suspension, see the Giant XTC JR Lite 24; for a disc-brake version, see the Giant XTC JR 24 inch Disc.

FAQ

What height is the Giant XTC JR 24 for?

Giant recommends it for riders 130–150 cm tall. The stand-over height is 616 mm, so you can measure your child's inseam to compare.

Should I choose a 20-inch or 24-inch kids' bike?

Go by height. Giant recommends the XTC JR 20 for 120–140 cm and the XTC JR 24 for 130–150 cm; kids who are 130–140 cm fall in both ranges, so inseam and riding experience decide it, and you can contact us before ordering. See the comparison table above for details.
