THE NEW IBIS OSO 1.1

February 18, 2025

The Oso is our powerful, adventure-ready e-bike, now updated for even more fun. It keeps everything you love, with a few new features that make an impactful difference to your ride experience. After continued feedback, testing, and improvements, we bring you a revised version of the perfect companion for any riding adventure.

Streamlined controls create a sleek, clutter-free cockpit, and the optional headlight is yours to install or leave off. The Oso also features an updated carbon fiber layup for a ride that feels more tailored to the demands of a long-travel e-bike—ensuring every ride feels like it’s downhill both ways.

DON’T JUST TAKE OUR WORD FOR IT.

“Pros: most fun bike I’ve ever ridden.
Cons: You won’t ride any other bike you have.
You may as well sell everything else.”
–Clark (Oso Owner | Bellingham, WA)

CLEAN INTERFACE

We removed the Kiox display and front light for an elegant and clutter-free handlebar set up. The Oso controller is now an integrated part of the frame and sits flush in the top tube. Paired with a wireless mini-remote on the bars, this brings a sleeker look and simpler interface, with no extra wires going between the frame and handlebar.

LIGHTS WHEN YOU NEED THEM

We’ve listened to your preferences, and it’s even easier to choose if you want a full time front light or not. We pre-wired the bike so you can add the included Lupine SL F Nano 900 lumen headlamp making it ride ready for dawn patrol or when you’re racing the sunset home.

The Oso comes with a Lupine C14 taillight (seat collar + rear tail light combo). This 45 lumen taillight is bright enough to be seen in traffic or to help guide your friends home after dark. The Lupine C14 taillight can also be removed and replaced with your seat collar of choice.

PRECISION LAYUP

With increased stiffness throughout the frame, the Oso delivers a more precise and confident ride. The updated carbon fiber layup is optimized for torsional stiffness while retaining a compliant rear end.

UPGRADED MOTOR GUARD AND DOWNTUBE PROTECTION

We beefed up the downtube and motor guards, with double the thickness and a toughened material. Stronger protection for more peace of mind.

TRIED AND TRUE BOSCH PERFORMANCE

The updated Oso 1.1 utilizes the vetted Generation 4 Bosch Performance Line CX motor, giving you smooth, responsive power with 85 Nm of torque. It’s paired with a UL-certified 750 Wh battery (or 625 Wh on the small size). Bosch back their system with a two-year warranty and excellent customer service. We have also expanded our Bosch service to international customers with a dedicated Ibis expert.

SUSPENSION

The Oso’s dw-link suspension delivers an effortless, no-bob feel, with efficient power transfer, whether you’re charging uphill or down. With 155mm of rear travel that can be converted to 170mm, the bike, the bike soaks up rough terrain and handles in a smooth, playful, and engaging manner.
