GX Build KitGeometrySpecifications


The Oso does­n’t just lean into enduro ter­ri­to­ry, it drops in, elbows out and gog­gles down. The long wheel­base, roomy cock­pit, and slack 64-degree head angle are designed for opti­mal rac­ing per­for­mance. Its size-spe­­cif­ic seat angles allow rid­ers of any height to bang out climbs in com­fort with­out wast­ing a watt.

Size / Chainstay / Wheel Configuration

Large and X-Large Oso frames are built around match­ing 29-inch wheels, while Small and Medi­um frames get the mixed-wheel treat­ment and short­er chain­stays. This keeps the Oso from ever feel­ing unwieldy. In fact, it’s pret­ty damn wieldy.

Motor / Battery

The Bosch Per­for­mance line CX has a qui­et, pow­er­ful 85 NM dri­ve unit, which offers the most nat­ur­al-feel­ing accel­er­a­tion since the inven­tion of grav­i­ty. On top of that, you get Bosch’s two-year war­ran­ty, UL safe­ty-cer­ti­fied bat­ter­ies, and its car­bon-neu­tral oper­a­tions.
With a deep 750wh bat­tery on sizes Medi­um thru X-Large and a 625wh bat­tery on the Small, the Oso is built to go big and still have enough juice left to go home.


It may look a lit­tle dif­fer­ent, but the Oso’s Upper Link sus­pen­sion is still dw-link. That means it packs all the trac­tion and effi­cien­cy you’d expect from an Ibis, but with a more sup­port­ive lever­age curve to keep up with all the demands of a full-pow­ered e‑bike. The Oso has 155mm of rear travel with 170mm up front.
