Origin

The Zircus arrived circa 2020 as NS Bikes deliberate investment in the next generation of dirt jump riders. Recognising that adult DJ bikes were too large and intimidating for younger riders, NS built a purpose-scaled platform — not a shrunken adult bike, but a properly engineered youth dirt jumper with correct geometry for smaller bodies.

Specifications

Frame: AL6061-T6 custom formed and butted tubes; tapered integrated headset (ZS44/ZS44 on 24in); one size (minimum rider height 120cm on 24in)
Weight: kg
Drivetrain: Single-speed; Samox 152mm cranks 26t (24in); PYC chain
Brakes: 24in: Alhonga v-brake front, Tektro MD-M300 Aries mechanical disc rear 160mm
Wheels: 24in aluminum NS JR 32h rims (Zircus 24); 20in (Zircus 20); single-speed rear axle

The verdict

+Strengths

Two wheel sizes (20in / 24in) provide a logical progression path within the same product family
Proper dirt jump geometry instils correct technique from the start
Competitive price for a brand-name youth DJ bike with NS build quality

−Weaknesses

Mixed braking (v-brake + mechanical disc) is inconsistent — one side is better than the other
Suntour XCM fork is adequate but not inspiring for ambitious young riders
Single-size frame limits fit range — some riders may outgrow it quickly
