The woom OFF AIR 6 is the most capable bike in the OFF line, with 90mm of tunable suspension

What Our Gearhead® Experts Are Saying:


"The step up to 90mm of travel with the F1RST fork is meaningful for a rider in the 10 to 14 range tackling real singletrack. Combined with the dropper-ready frame, 11-36T cassette, and 150mm cranks proportioned for this age group, the OFF AIR 6 is built for a teen who is treating trail riding seriously and needs a bike that can keep pace with where their skills are heading."


The OFF AIR 6's 6061-T6 aluminum frame uses the same butted and hydroformed construction as the OFF 6, with a dropper seatpost-ready seat tube and a low top tube for easy dismounts on more technical terrain. The F1RST hydraulic air suspension fork runs 90mm of travel on a pressure-adjustable air spring, with independent compression and rebound damping controls and a lockout for smooth surfaces. That level of adjustability matters at this size because a fork tuned to a teen rider's actual weight and riding style delivers meaningfully different trail feel than one left at a factory default. SRAM X5 trigger shifters index through 9 speeds backed by an 11-36T cassette and 28T narrow-wide chainring, the widest range in the OFF line. Promax hydraulic disc brakes run 160mm rotors front and rear with child-tuned lever reach. Schwalbe Rocket Ron 26 x 2.35" tires with ADDIX SPEED compound balance rolling efficiency with grip on loose terrain. The tubeless-compatible Alexrims wheelset runs 28 G14 triple-crossed spokes with aluminum nipples and thru axles front and rear. The 150mm child-specific cranks maintain a narrow Q-factor for the 10 to 14 age range, and the flip-flop stem adjusts handlebar height without additional hardware.


Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
