A bike they can grow with, the Line 24 is a junior version of our do-anything hardtail mountain bike. Equipped to handle the abuse of real mountain bike trails and daily use around the neighborhood, it's made from the same aluminum alloy as our full-size bikes, so it's practically indestructible. An SR Suntour fork performs like the big people's bikes, giving your ripper-to-be 80mm of front suspension travel. The 24-inch wheels are stiff and stable, shod with aggressive 2.25-inch wide Vee Rubber tires, perfect for tearing up the woods. Disc brakes and a wide-range SRAM 1x8 drivetrain are real performance features, underscoring that the Line 24 is a legit mountain bike—only smaller. This model fits riders 53"-62" tall, aged approximately 8-12 years old.

- Tektro Aries mechanical disc brakes with 160mm rotors has adjustable-reach levers, perfect for fast-growing hands
- SR Suntour XCT suspension fork with 80mm of travel takes them over roots and rocks with ease
- SRAM 8-speed drivetrain provides ample gears for hills and rolling descents without the fuss of a front derailleur
