Review: 2023 Ibis Oso

Feb 2023 · Mike Kazimer

As it turns out, Oso hides its dimensions very well, and there's a ton of stability thanks to the longer wheelbase, which comes in handy when you're working up through a technical section of trail.

Highs
  • Good mix of traction & pep from rear suspension

  • Big bike feel without being cumbersome

  • Bosch CX motor, 750 Wh battery, and lights allow for extra-long rides.

Lows
  • Cluttered cockpit due to wired remote and display

  • Flimsy battery cover and charging port

  • Only one model, and it's not cheap.
