Ibis

Oso GX Transmission Ebike

What Our Gearhead Experts Are Saying:

"The Oso is a dream for aggressive riders who want e-bike power without sacrificing downhill performance. The Bosch motor delivers smooth, responsive assistance without overwhelming the ride feel, and the 750Wh battery lets me push deeper into the mountains. The Fox 38 fork and dw-link suspension make rock gardens disappear, and the mixed-wheel setup keeps it nimble in tight terrain. If you want an e-MTB that truly rides like a high-performance enduro bike, this is it."

The Oso isn't just an e-MTB-it's a category-defining machine designed for riders who want to push their limits. Built around a full-carbon frame, the Oso's powerful Bosch Performance Line CX motor delivers 85Nm of torque for smooth, controlled acceleration, while the 750Wh battery (625Wh on S size) provides massive range for all-day rides. The integrated top tube controller and bar-mounted wireless remote offer intuitive control without cluttering the cockpit.

Suspension performance is dialed with a dw-link rear setup providing 155mm of travel, paired with a Fox Performance 38 fork up front for unmatched small-bump compliance and big-hit control. Ibis' progressive geometry ensures confidence on steep descents while maintaining efficiency on technical climbs. The mixed-wheel design on smaller sizes enhances maneuverability, while full 29-inch wheels on larger frames maximize speed and stability.

Drivetrain and braking components are race-ready, with a SRAM GX Eagle Transmission shifting smoothly under load and Shimano XT 4-piston brakes paired with oversized 220mm rotors for ultimate stopping power. Whether tackling steep, technical climbs or bombing high-speed descents, the Oso is built to handle anything, making it the perfect companion for aggressive e-MTB riders looking to redefine what's possible.

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.
