Description
Dirt skills start with the 2026 Giant STP 20" FS boy's bike. Featuring a lightweight aluminium frame that has a low stand-over height, a 63mm suspension fork, and 20-inch wheels, the new STP 20 gives kids the confidence and manoeuvrability they need to start leaning into the turns, shifting their weight, and popping some air. It’s all the things that make riding fun, safe and rewarding.
FIT FOR YOUTH
The frame’s low stand-over height offers greater balance and stability with a lower centre of gravity that’s ideal for riders 110-130cm tall. The 20-inch wheels and shorter 105mm cranks make for easier handling and smoother pedalling.
GREATER CONTROL
Youth-specific components including a Grit Core Lite saddle, smaller diameter handlebars, and hydraulic brakes with lighter modulation give STP 20 a smooth, controlled ride, helping young riders focus on building skills and gaining confidence.
PLAYFUL AGILITY
With a lightweight, durable ALUXX aluminium frame and suspension fork, the STP 20 is easy for young riders to manoeuvre. A shorter wheelbase and chainstays add a playful feel and make it easier to lift the front wheel while riding.
Size: Suit rider height 110 - 130cm
