The Ibis Oso Trail Eagle 90 Ebike goes anywhere and handles everything
What Our Gearhead® Experts Are Saying:
"I reach for the Oso Trail Eagle 90 Ebike when I want a trail bike that truly does it all. The RockShox Lyrik Base fork and Super Deluxe Select+ shock deliver a balanced, capable ride, and the Bosch CX Gen 5 motor with 100Nm keeps the climbs manageable without killing the natural trail feel. The BikeYoke dropper is a nice touch that shows Ibis thought carefully about this build."
Who It's For
Trail riders who want a do-everything eMTB for longer days and bigger terrain.
The Oso Trail Eagle 90 Ebike suits confident riders who want a bike that climbs efficiently and descends capably across a wide range of trail conditions.
What It's For
Singletrack, all day missions, and terrain that rewards balanced travel.
The Oso Trail Eagle 90 Ebike is built for riders who want to cover more ground. With 160mm up front and 150mm rear, it handles technical trail terrain while staying efficient enough for longer efforts. The 600Wh battery with PowerMore compatibility means range is rarely a concern.
Why We Like It
Balanced geometry, a thoughtful build spec, and a Bosch motor that transforms what is possible.
The Ibis Oso Trail Eagle 90 Ebike is built around a full carbon frame with trail focused geometry across five sizes. At 160mm front and 150mm rear, it sits in the sweet spot between efficiency and capability, comfortable on climbs and confident on descents.
The RockShox Lyrik Base fork and Super Deluxe Select+ shock deliver a lively, active ride feel that rewards an engaged rider. SRAM Maven Base brakes provide reliable stopping power, and the SRAM Eagle 90 Transmission with a 10 to 52 tooth cassette handles every gradient without hesitation.
Bosch CX Gen 5 puts out up to 750W and 100Nm with a natural pedal feel suited to long days on varied terrain. The 600Wh PowerTube battery is PowerMore compatible for up to 850Wh total, and the BikeYoke dropper post rounds out a build spec that is thoughtful from top to bottom.
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.
