Ibis Oso

The Ibis Oso uses a 'mullet' setup for Small and Medium frames, pairing a 29-inch front wheel with a 27.5-inch rear wheel. This configuration provides the rollover capability of a larger front wheel while keeping the rear end nimble and easier to maneuver through tight, technical sections.

Yes, the bike comes pre-wired with a 900-lumen front light and an integrated taillight powered directly by the main battery. It is a robust, clean solution that eliminates the need to charge separate lights or manage external cables.

With 170mm of travel up front and 155mm in the rear, the Oso is designed for demanding terrain. The dual-link suspension system is tuned to provide a supportive platform for climbing while remaining plush and controlled during high-speed, technical descents.

While range varies significantly based on rider weight, terrain, and assist mode, the 750Wh battery is one of the largest available, comfortably supporting long days on the trail. You can expect to tackle substantial elevation gain, though using the highest assist modes will naturally deplete the charge faster.

The SRAM GX Eagle Transmission is highly durable and requires less maintenance than traditional cable-actuated systems because there are no cables to stretch or housing to clog. You will simply need to ensure the derailleur battery is charged periodically, which is easily monitored via the SRAM AXS app.

By housing the controller in the top tube, Ibis has created a significantly cleaner cockpit with fewer cables running to the handlebars. This design not only looks streamlined but also reduces the risk of snagging cables on trailside obstacles.
