IBX is Icebear's off-road division, built for trails, tracks, and backyard riding. The lineup runs from the 70cc GRZ70, sized for young riders who've graduated from training wheels, up to the 150cc GRZ150 for adult-sized riders who want real off-road capability.
The AX series (AX90, AX125, AX140) and the Roost series (Fully Auto and Semi Auto 125cc versions) are pit bike specialists, with race-inspired geometry and four-stroke engines built for repeated abuse. The GRZ family (70, 125, 125-D, 125UT-D, 150) splits the difference between pit bike and full dirt bike. The Whip 125cc rounds out the catalog with a recreational rider in mind.
All IBX models ship with EPA and CPSC certification. Icebear has been building affordable off-road bikes since 2006 and distributes through 300+ U.S. dealers, so parts and service are never far from where you ride. Pick a model below to see specs and find your nearest dealer.
Common Questions About IBX Offroad Bikes
What's the difference between a pit bike and a dirt bike?
Pit bikes are smaller, lower to the ground, and built for tight tracks, backyards, and learning. Dirt bikes are larger, with longer suspension travel, designed for trails and bigger jumps. The AX and Roost series in our IBX lineup are pit bikes; the GRZ series spans both categories depending on size.
What age is the GRZ70 designed for?
The GRZ70 is sized for young riders who've outgrown training wheels but aren't ready for a full-size off-road bike. The exact age depends on the rider's height and confidence, but most owners pair it with riders age 7 to 12. Adult supervision and protective gear are always recommended.
Are IBX off-road bikes street-legal?
No. The IBX lineup is built strictly for off-road use. They aren't fitted with DOT-compliant lighting, mirrors, or signaling, and they aren't designed to be registered for street riding. Use them on private property, designated off-road parks, or trails where off-road vehicles are permitted.
What's the difference between the AX and GRZ series?
AX bikes are pure pit-bike geometry with shorter wheelbases and lower seat heights, designed for tracks and tight technical riding. GRZ bikes have longer travel, taller seat heights, and a more trail-oriented stance. Riders who race or ride pit bike tracks usually pick AX. Riders who want a general trail bike pick GRZ.
Where can I get parts for my IBX bike?
Parts diagrams for every IBX model are available on our Parts page. Authorized Icebear dealers stock the most common service parts, and any dealer can order what's not on hand. Our 300+ dealer network means service support is rarely far from where you ride.
