Designed for Young Riders Who Want to Progress
The STP 24 FS is built for more than simple neighborhood transportation. Its geometry and equipment are intended for young riders who want to develop skills on dirt, street, pump tracks, and bike parks.
The 24-inch wheels keep the bike compact and maneuverable, while the suspension fork provides additional control when riding across uneven surfaces.
The result is a youth bike that can accommodate a wide variety of riding styles as a young cyclist develops confidence and technique.
Lightweight ALUXX Aluminum Frame
The frame is constructed from ALUXX-grade aluminum, giving the bike a useful balance of strength, stiffness, and weight.
Giant uses 6061 alloy tubing with single-butted construction on the STP 24 FS. The frame is specifically proportioned for its 24-inch wheels rather than simply scaling down an adult mountain bike.
This helps provide a manageable riding position and predictable handling for younger cyclists.
SR Suntour XCT L24 Suspension Fork
At the front of the bike is an SR Suntour XCT L24 coil-spring suspension fork.
The fork offers 80mm of travel, helping absorb impacts from bumps, roots, rough dirt, and other trail irregularities.
A lockout function allows the fork to be firmed up when suspension movement is not necessary, such as when riding on smoother paved surfaces.
The combination of suspension and a rigid rear frame gives the bike additional comfort and control without the complexity of a full-suspension system.
24-Inch Wheelset
The STP 24 FS uses 24-inch wheels, providing a practical balance between stability and maneuverability for younger riders.
The Giant alloy rims have a 28mm internal width, providing a suitable platform for the bike's 2.2-inch tires.
The wheelset uses disc-specific hubs with quick-release axles and 28 spokes.
Kenda Karma 24 x 2.2 Tires
The bike comes equipped with Kenda Karma 24 x 2.2-inch tires.
Their relatively wide profile provides a stable contact patch and helps give young riders additional traction on dirt and uneven surfaces.
The tires are suitable for the STP's intended mix of:
Dirt trails
Pump tracks
Gravel paths
Bike parks
Paved streets
Neighborhood riding
MicroSHIFT Acolyte 1x8 Drivetrain
The STP 24 FS uses a MicroSHIFT Acolyte 1x8-speed drivetrain.
A single-chainring setup eliminates the need for a front derailleur, simplifying gear changes for young riders. The rider only needs to operate the rear shifter to select the appropriate gear.
The drivetrain combines a 30T front chainring with a 12-42T cassette, providing a wide range of gears for climbing and faster sections.
Drivetrain Components
MicroSHIFT Acolyte 1x8 shifter
MicroSHIFT Acolyte rear derailleur
Forged alloy 30T crankset
140mm crank length
MicroSHIFT Advent 12-42T cassette
KMC Z8.3 chain
Cartridge bottom bracket
The wide-range cassette provides a relatively easy climbing gear while keeping the drivetrain straightforward to operate.
Tektro Hydraulic Disc Brakes
The bike uses Tektro HD-J285 hydraulic disc brakes with 160mm rotors front and rear.
Hydraulic disc brakes provide smooth lever modulation and predictable stopping power. This is useful for young riders who are beginning to tackle steeper paths, faster descents, and more technical terrain.
Because the brakes operate through dedicated rotors, braking performance is independent of the wheel rims and remains compatible with the bike's wide tires.
Youth-Specific Cockpit
The STP 24 FS uses a Giant Sport alloy handlebar with a 31.8mm clamp diameter.
The handlebar is paired with Giant Junior grips and a forged alloy stem with a 0-degree rise.
This setup creates a direct, easy-to-control steering position that suits the bike's compact frame and intended riding style.
Seatpost and Saddle
A 30.9 x 300mm alloy two-bolt seatpost supports the rider's position.
The bike uses a Giant Jr. Sport saddle, designed around the proportions of younger riders.
Platform pedals are supplied, providing a simple interface suitable for everyday riding.
Youth-Specific Geometry
The STP 24 FS uses a one-size frame developed around its 24-inch wheels.
Its geometry is intended to keep the bike compact and responsive while providing enough stability for trail and park riding.
| Geometry | Specification |
|---|---|
| Top Tube Length | 495mm |
| Head Tube Length | 105mm |
| Head Tube Angle | 69° |
| Seat Tube Angle | 73° |
| Wheelbase | 978mm |
| Chainstay Length | 410mm |
| Stack | 524mm |
| Reach | 335mm |
| Standover Height | 603.2mm |
| Crank Length | 140mm |
The 69-degree head angle provides a more trail-oriented setup than many basic children's bikes, helping give the STP 24 FS a stable feel when riding over uneven ground.
Ideal Uses
Trail Riding
The suspension fork, wide tires, and hydraulic disc brakes make the STP 24 FS capable of handling recreational trails and uneven dirt surfaces.
Pump Tracks
Its compact geometry and responsive 24-inch wheels make it suitable for young riders developing cornering, pumping, and bike-control skills.
Bike Parks
The bike's suspension and hydraulic braking system give it additional capability for appropriate youth-oriented bike-park terrain.
Dirt Riding
The 2.2-inch tires and 80mm fork provide useful traction and impact absorption on packed dirt and mild off-road routes.
Street Riding
The STP can also be used for neighborhood and paved-path riding. The fork lockout can help create a firmer feel when suspension movement is unnecessary.
