SUNPEED HERO Kids Mountain Bike
Whether it’s their first trail ride or a confident cruise through the neighborhood, the SUNPEED HERO is built to keep up. Available in 20″ and 24″ sizes, it features a lightweight 6061-T6 aluminum frame, a smooth suspension fork, and real trail-ready components.

Equipped with a Shimano Altus 9-speed drivetrain and hydraulic disc brakes, the HERO offers precision, power, and control – just like a full-size mountain bike. With grippy CST 2.125″ tyres, sealed cartridge bearings, it’s designed for kids who ride like pros. 

Small frame. Big attitude. SUNPEED HERO delivers.
Every SUNPEED kids bike currently includes a FREE Mavic Junior Helmet worth £35. Available while promotional stock lasts.

How long does delivery take, and how much does shipping cost?
