The Ibis Oso eMTB Gets a Makeover - One Frame, Three Travel Options

Why It Matters

The redesign addresses early criticism while delivering a versatile platform that can serve trail, enduro and all‑mountain riders, strengthening Ibis’s position in the fast‑growing e‑mountain‑bike market.

Key Takeaways

• New Oso uses real rear triangle, dropping the controversial girder swingarm
• Offers three travel options on same carbon frame, from 130 mm to 165 mm
• Bosch Gen 5 CX motor with 600 Wh removable battery starts at $7,999
• Modular drop‑outs allow MX or 29″ wheels and adjustable chainstays
• Lifetime frame and bushing warranty included, frame‑only price $6,599

Pulse Analysis

Ibis’s overhaul of the Oso arrives at a pivotal moment for electric mountain bikes, as consumers demand both performance and adaptability. By abandoning the split‑beam swingarm that sparked debate in 2023, the new Oso adopts a more conventional rear‑triangle design that improves rear‑wheel traction and simplifies maintenance. The modular drop‑out system lets riders switch between MX and 29″ wheels and fine‑tune chainstay length, effectively turning a single frame into three distinct bike categories—S, TR and HD—without sacrificing structural integrity.

Technically, the Oso is anchored by Bosch’s Gen 5 CX motor, delivering up to 100 Nm of torque and paired with a 600 Wh removable battery that sits lower in the frame for better balance. The motor’s 750 W peak power, combined with a 64° head angle on the TR model and adjustable rear‑center ranging from 440 mm to 465 mm, offers a blend of climbing efficiency and descending stability. Weight claims of 50.2 lb (22.77 kg) in the XM size represent a modest reduction over the 2023 version, largely due to the smaller battery, while still providing a robust suspension platform with a Dave Weagle twin‑link system.

Pricing reflects Ibis’s strategy to capture both entry‑level and premium segments. A frame‑only kit at $6,599 invites custom builds, whereas fully‑kitted models range from $7,999 to $9,699, positioning the Oso competitively against rivals like Specialized’s Turbo Levo and Trek’s Powerfly. The lifetime frame and bushing warranty underscores confidence in durability, a key selling point for riders wary of early‑generation e‑bike reliability. As e‑MTBs continue to gain market share, Ibis’s versatile, warranty‑backed Oso could become a benchmark for modular design in the industry.
