NS Bikes Zircus 26-Inch 2025 Bike

The Zircus is the perfect tool for mastering pump track skills: bunnyhops, manuals, 180s and all the other moves in the ABC of mountain biking. It uses the same light, strong aluminium frame as NS's Movement range, built up with affordable but high-quality parts. Perfect for playing in the city, off-road or on pump tracks. The compact single-speed drivetrain saves weight and gives it that pro look. An optional derailleur hanger lets you convert it to gears if needed.
