SCOTT Scale 400 – 24″ Kids/Youth Alloy Hardtail
Give young riders the confidence to explore trails, parks and neighbourhood rides with the SCOTT Scale 400 — a purpose-built 24″ wheel alloy hardtail designed for beginning riders who demand durability, simplicity and fun.
Built for younger riders who want to ride more
At around 9.8 kg the Scale 400 offers a lightweight, manageable ride for smaller frames, with a size-specific cockpit featuring a 560mm width riser bar, 50mm stem and Syncros Kids III saddle for easy control.
The alloy 6061 custom-tube frame and rigid aluminium fork keep things low-maintenance while still offering reliable performance off-road and on everyday adventures.
With 24” wheels, hydraulic disc brakes front and rear (Tektro HD-M276 with 160 mm rotors), and an 8-speed Shimano Tourney drivetrain (11-34T cassette), the bike gives young riders climbing ability, confident stopping and real trail capability.
The Kenda K1227 Booster 24×2.2″ tyres provide a stable footprint across tarmac and gravel, making the Scale 400 a versatile machine for after-school rides, weekend trail loops or exploring local singletrack.
Why parents and riders love it
-
Kid-specific geometry: fit for riders from approx. 125 cm height, delivering better handling and control.
-
Solid component build: hydraulic disc brakes and an 11-34T cassette give more capability than many entry-level kids bikes.
-
Light enough to carry and manoeuvre: ~9.8 kg means young riders won’t feel weighed down.
-
Built to go off-road: rigid fork teaches line-choice and handling, while the frame has the durability to handle bumps, roots and the occasional tumble.
Ideal for
Young riders stepping up from stabilisers or smaller bikes, who want a machine that can handle both the neighbourhood and the trail. If you’re looking for one bike to cover after-school rides, pump-track fun and first proper outings off-road — the Scale 400 delivers.
