YT JEFFSY PRIMUS 24 kids mountain bike
Playful, fast, and infinitely fun, the JEFFSY PRIMUS 24 is a hard-hitting MTB for up-and-coming shredders between 135cm and 150cm tall. Wherever you ride, this bike brings the Good Times; technical descents, heavy sends, and formidable climbs, it does it all, and it’s built tough to go the distance.
The lightweight aluminum frame is ultra-durable and equipped with the same quality components found on our adult bikes, including adjustable air suspension and confidence-inspiring four-piston brakes, alongside Maxxis tires for endless traction on loose terrain. Grip it and rip it! The PRIMUS 24 features an SDG Slater cockpit with a reduced-diameter handlebar and grips to fit smaller hands and enhance control.
