The Ibis Oso Sport Eagle 90 Ebike is built for riders who love the trail
What Our Gearhead® Experts Are Saying:
"I reach for the Oso Sport Eagle 90 Ebike when I want a trail bike that feels truly alive. The RockShox Pike Base fork and Deluxe Select+ shock deliver a responsive, active ride, while the SRAM Maven Base brakes and Eagle 90 Transmission keep you in control. The Bosch CX Gen 5 motor with 100Nm makes longer climbs feel shorter without killing the natural trail feel."
Who It's For
Trail riders who want a capable eMTB for fast and fun everyday riding.
The Oso Sport Eagle 90 Ebike suits riders who want a responsive, capable trail bike that grows with them across all terrain.
What It's For
Local trails, flowing singletrack, and all day rides worth repeating.
Built for tight corners, punchy climbs, and flowing terrain that rewards an agile setup. The 600Wh battery keeps you out longer on the trail.
Why We Like It
Responsive suspension, reliable brakes, and a Bosch motor built for the trail.
Full carbon frame with trail focused geometry across five sizes. At 140mm front and 130mm rear, it is nimble on tight terrain and composed on longer days.
RockShox Pike Base fork and Deluxe Select+ shock deliver an active ride feel. SRAM Maven Base brakes and SRAM Eagle 90 Transmission with 10 to 52T cover everything.
Bosch CX Gen 5 puts out up to 750W and 100Nm with a natural trail feel. The 600Wh battery is PowerMore compatible for up to 850Wh total.
Heads up. We do our best to keep bike specs and images current, but occasional component changes can happen without warning and sometimes the photos might not show the exact build you'll receive. If you want to double check the details, our Gearheads are always here to help.

One Frame, Three Trail Modes

Find Your Model
OSO HD
Shuttle laps and big mountain descents
180mm front / 165mm rear travel
Gravity geometry gets riders to the top faster for another run down
OSO Trail
All-day missions and backcountry access
160mm front / 150mm rear travel
Efficient enough for long climbs, capable enough for technical descents
OSO Sport
Local trails and fast flowing singletrack
140mm front / 160mm rear travel
Less travel makes the bike more responsive and agile on tighter terrain
Inside The Oso
Quiet Motor, Real Torque
The Bosch Performance Line CX Gen 5 runs quiet on the trail. It delivers high torque with natural-feeling pedal assist that responds to input rather than fighting it
All-Day Battery, More If You Need It
The internal 600Wh battery sits low in the frame, improving balance and handling. Add the optional PowerMore 250Wh extender to reach 850Wh total for longer routes
Built To Change With Your Riding
Swap the shock and fork to convert between HD, Trail and Sport travel. Bolt-on dropouts let riders fine-tune chainstay length and switch between 29" and 27.5" rear wheels
Five Sizes, All Dialed
Every frame size gets its own geometry, so the bike fits and handles correctly for your height. A new Extra Medium sits between Medium and Large, covering the height range where 80% of Ibis riders land
Full Suspension, No Compromise
dw-link suspension manages pedaling, braking and trail input independently, so the bike stays efficient on climbs and controlled on descents

Built To Fly
Ibis Cycles started in 1981 when founder Scot Nicol opened a tiny workshop near Mendocino, California, with no big plan beyond building mountain bikes that were fun to ride and tough enough for the rough stuff. Today, from its home base in Santa Cruz, Ibis remains a small, rider-owned company focused on doing a few things really well: designing carbon and aluminum mountain bikes that climb efficiently, descend playfully, and feel lively every time you point them down the trail. With long-time owners and in-house engineering still deeply involved in the day-to-day, the brand stands for bikes that are light, durable, and above all, a blast to ride—whether you are racing, lapping local trails, or just chasing that next perfect corner.
