The BMC Blast is an innovative cross country bike built specifically for developing riders. This lightweight wonder, engineered for safety and control, grows with the novice rider allowing extensive exploration of the trails with comfort and confidence. This custom-made ride showcases state-of-the-art geometry with tailored ergonomics and provides an intuitive and reliable performance. Crafted from an Al-13 double-butted, smooth-welded aluminum tubing, the SDG cockpit and saddle ensures this XC bike will empower all riders. 

This 20" design, engineered for ages 5-8 years, is a game-changer for beginners. The SRAM 1x8 drivetrain provides a wide range of gear travel while the Tektro hydraulic brakes and 140mm rotors with Kenda Booster low rolling resistant tires promise formidable stopping on any terrain. For long-lasting performance, a durable powder-coated finish provides protection against rust and corrosion. Blast Sticker kits are included to give this bike a personality that reflects the rider.
