Description
TRAILS ALL DAY
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.
The Ibis Oso TR is the do-it-all trail e-bike built for riders who want one machine that can handle everything from after-work laps to full-day backcountry missions. Blending balanced geometry, efficient suspension, and Bosch’s latest drive system, the Oso TR delivers confident climbing, playful handling, and impressive descending capability in one refined package.
With 150mm of rear travel paired to a 160mm fork, the Oso TR hits the sweet spot between efficiency and aggression. It pedals crisply on long climbs yet stays composed and planted when trails turn steep, rough, or fast. Ibis’ proven dw-link suspension platform delivers excellent traction and support while maintaining the lively ride feel that makes technical terrain fun instead of overwhelming.
Power comes from the Bosch Performance Line CX Gen 5 motor, offering up to 120Nm of torque with smooth, natural-feeling assist that responds intuitively on technical climbs and changing terrain. A 600Wh internal battery provides plenty of range for most rides while keeping overall system weight lower for better handling. For bigger adventures, the frame is fully compatible with Bosch’s 250Wh PowerMore range extender, bringing total capacity up to 850Wh.
The Oso TR is designed around adaptability. Smaller sizes use a mixed-wheel setup for agility and fit optimization, while larger sizes roll on dual 29” wheels for stability and speed. Thanks to the modular dropout system, riders can fine-tune wheel configuration and chainstay length to suit their riding style or terrain.
Everything about the chassis is purpose-built for modern trail riding. Progressive geometry, size-specific kinematics, long dropper compatibility, generous tire clearance, and integrated frame protection all work together to create a bike that feels balanced, capable, and ready for anything.
