OSO TR

Powered by a Bosch CX Gen 5 motor, the Oso TR is a do-everything trail companion, efficient enough for all-day missions, yet lively and capable on the descents. From after-work laps to full-blown backcountry adventures, the TR delivers a balanced ride that goes anywhere and everywhere.

OSO TR Features

Modular Chassis

Swap the shock, clevis, and fork to make any of the three travel lengths
29” and 27.5” compatible

Modular Dropout System

Bolt-on dropouts and brake mounts allow riders to fine-tune chainstay length and wheel size configuration.

27.5” rear wheel: The Oso HD ships with the 440mm dropout on SM/MD and 455mm dropout on the XM.
Both 27.5 dropout sizes (440mm and 455mm) will be available aftermarket.

Both 29” dropout sizes (455mm and 465mm) will be available aftermarket.

Bosch Performance Line CX Drive Unit

Bosch’s Gen5 motor features quiet, powerful, natural-feeling pedal assist and refined torque delivery for technical terrain. Gen 5 with [Top Secret] Nm torque, and power multiplier. Supported by the trusted Bosch service network.

Kiox 400c Display

Included as standard, providing best-in-class user interface and ride metrics.

Size Specific Everything

Ensures consistent handling and ride feel across all frame sizes (SM-XL) by customizing geometry, chainstay lengths, bottom bracket heights, and suspension kinematics for every bike.

DW Link Supension

The Oso is built around the highly regarded dw-link suspension platform, known for its efficient climbing and confident descending performance. Evolving from race-proven design principles, it features a more progressive shock rate and a shorter clevis for compatibility with a wide range of coil shocks.

Size-specific kinematics ensure each frame pedals efficiently while maintaining composure, traction, and quiet performance across technical terrain.

Uninterrupted seat tube design maximizes insertion depths, allowing for the use of long-travel dropper posts across the entire size range.

600Wh internal battery and optional PowerMore 250Wh range extender compatible (sold separately), delivering a total capacity of 850Wh.

Low and centered battery placement improves balance and handling.
600Wh provides sufficient range for the majority of rides and a lighter system weight. Adding the PowerMore opens up longer routes and all-day epics.
A thoughtfully positioned charge port allows for use of the shortest PowerMore cable for fuss-free integration.

Fits most 2.5 tires.

If it's our fault, we'll fix it. Simple as that.
Lifetime frame warranty.
Lifetime bushing warranty.
Two year Bosch warranty.
