A whole new sport demands a whole new bike. Built from the ground up to deliver a new level of smooth, fast, and durable performance, the full-carbon-fiber Oso features our first-ever upper-link suspension dw-link platform. It stacks 155mm of rear travel with 170mm up front and is powered by a Bosch Performance line CX motor.


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. And its size-spe­­cif­ic seat angles allow rid­ers of any height to bang out climbs in com­fort with­out wast­ing a watt.

Size specific chainstays and wheel configuration

Large and extra large Oso frames are built around match­ing 29-inch wheels, while small and medi­um frames get the mixed-wheel treat­ment and short­er chain­stays. That keeps the Oso from ever feel­ing unwieldy. In fact, it’s pret­ty damn wieldy.

Why Bosch?

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, a net­work of 2,400 deal­ers across the U.S., UL safe­ty-cer­ti­fied bat­ter­ies, and its car­bon-neu­tral oper­a­tions. So, in case you were won­der­ing, that’s why we went with Bosch.

Big Battery

With a deep 750wh bat­tery on sizes medi­um thru XL and a 625wh bat­tery on the small, the Oso is built to go big and still have enough juice left to go home.

Upper link suspension

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.

Lifetime Warranty

If it’s our fault, we’ll fix it. Sim­ple as that.
