The Liv STP 20 FS Kids Mountain Bike is a lightweight and confidence-building 20-inch bike designed for young riders discovering off-road riding, pump tracks, dirt trails, and everyday adventures. Its ALUXX-grade aluminium frame combines low weight with durable construction, while the low standover height and youth-focused geometry help younger riders feel balanced and in control.
A 63 mm SR Suntour XCT Jr. suspension fork helps absorb bumps and rough terrain, giving young riders added comfort and traction as their skills develop. The MicroSHIFT Acolyte 1 x 8-speed drivetrain provides simple, intuitive shifting with a useful 11-38T gear range, while short 105 mm cranks are designed specifically around smaller riders.
Tektro hydraulic disc brakes provide smooth and predictable stopping power, while 20-inch Giant TRA 2 alloy wheels and wide Kenda Amrak 20 x 2.2-inch tyres deliver grip and stability on mixed terrain. Finished in Hot Pink, the STP 20 FS combines proper mountain-bike components with kid-specific sizing for riders ready to progress beyond basic recreational cycling.
