The woom OFF 6 is a 26in kids' mountain bike that takes a teen rider from trails to technical terrain
What Our Gearhead® Experts Are Saying:
"For a parent buying a mountain bike for a 10 to 14 year old who takes trail riding seriously, the OFF 6 is worth a close look. The longer cranks, wider bars, and 11-36T cassette are all sized for what a bigger rider actually needs, and the dropper-ready frame means the bike can grow with them as the terrain gets more technical."
A carbon fork, 9-speed SRAM drivetrain, and hydraulic disc brakes in a 26" package built for riders aged 10 to 14 who are covering real terrain. The OFF 6 steps up from the OFF 5 with longer 150mm cranks proportioned for this age group, wider 665mm bars for more control at higher speeds, and an 11-36T cassette that adds range for more demanding climbs. Schwalbe Rocket Ron 26 x 2.35" tires with ADDIX SPEED compound deliver low rolling resistance on hardpack and solid grip when the surface gets loose. The dropper seatpost-ready frame gives a progressing rider the option to add one without switching bikes. Tubeless-compatible Alexrims with triple-crossed spokes, thru axles front and rear, and a flip-flop stem round out the build.
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.
