Attention, watch out for discs!

From now on bike-crazy kids will not have to do without the stuff that makes their parents' hardtails perform so well: compact frame, super-light aluminium fork, hydraulic disc brakes with precise modulation and a 1x drivetrain. And STEVENS' engineers have done their best to keep it all under 10 kg (22 lbs).

  • Sporty compact frame w/ extra low standover height
  • Extra light due to aluminium fork and triple butted frame tubes
  • Hydraulic disc brakes w/ kid-friendly lever reach
  • Single chainring for intuitive 8-speed shifting
  • Kid-size crank arm length, suitable gear spread
