Zircus Black 2025

Perfect for playing in the city, off-road and on pumptracks. Our fun machines are built with the same DNA as our dirt and mountain bikes and come in multi-functional, budget friendly packages that riders of all levels will love. The Zircus is the perfect tool for mastering pumptrack skills, learning bunnyhops, manuals, 180’s and other fun stuff you can do just about anywhere. It’s important to keep in mind that all those skills are the ABC of riding mountain bikes, and you will also need them on your your 6000€ carbon full suspension bike!

The Zircus has the same lightweight and strong aluminum frame set that is used in the Movement range and is built using affordable but good quality parts making this bike perfect for playing in the city, off-road or on pumptracks. The bike has a compact drivetrain that saves weight and gives it tha ‘pro’ look. An optional derailleur hanger is available so you can convert this bike from single speed to gears if needed.
