Oso 1.1 Complete E-Bike - 2025

Highlights

Description

CLEAN INTERFACE
They 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
Ibis has listened to your preferences, and it's even easier to choose if you want a full time front light or not. They 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
They 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 backs their system with a two-year warranty and excellent customer service. They have also expanded their 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
