Reviews

Summary

The Orbea Oiz trail bike is praised for its lightweight design, efficient pedaling, and modern geometry that enhances both climbing and descending capabilities. Its suspension performance is noted for being plush and deep-feeling, offering excellent grip and control on rough terrain. However, some reviews mention issues with internal cable routing and a firmer suspension feel on square edge hits.

Pros
  • Lightweight and efficient pedaling

  • Modern geometry for improved descending

  • Plush and deep-feeling suspension

  • Good value for money in the lineup

  • Customization options under the MyO program

Cons
  • Internal cable routing through the headset

  • Firmer suspension feel on square edge hits

  • Rear-end tends to skip under braking

  • Chain slap noise due to minimal chainstay protection

Key Quotes

First Rides! New Orbea Oiz Favors Bold Lines, Strong Legs

Jun 2026 · Tyler Benedict

The 2027 Orbea Oiz is a race bike that seems just as much at home on all-day trail rides, making it both fun and fast.

Highs
  • Balanced geometry and weight distribution enhance climbing and descending.

  • Frame is stiff and planted, inspiring confidence in rough terrain.

  • Custom MyO program offers extensive build options including suspension, tires, drivetrain, brakes, paint.

  • Fits two water bottles on all sizes.

  • Tinted clear coat shows carbon weave.

  • Easy to carry cyclocross-style.

Lows
  • Pedal-induced movement noticeable with suspension open; racers will want lockout.

  • Flight Attendant adds cost and extra batteries.

  • Squidlock remote lever position can be awkward and rub thumb.

  • Fox suspension preferred over Flight Attendant for all-day ride quality.

Orbea Oiz M21 mountain bike review

Apr 2025

The Orbea Oiz M21 might be the brand’s entry-level carbon cross-country bike, but it’s far from basic. With impressive performance and solid componentry, it’s a capable machine for riders looking to push their limits. Some quirks and areas would welcome improvements, but the Oiz M21 still delivers a fast and efficient ride, both uphill and down. Rockrider RACE 900S mountain bike review Canyon Lux Trail CFR review Trek Top Fuel 8 Gen 4 mountain bike review The Oiz lineup features 120mm of travel and comes in alloy and carbon framesets.

Orbea Oiz M-TEAM first ride review

Nov 2022 · Tom Marvin

Add extra travel to longer geometry and you've got a recipe for downhill success. Orbea has avoided compromising uphill performance, too

Highs
  • Extra travel gives you a get out of jail free card

  • Geometry is at the forefront of XC design

  • Fast, up and down

  • Customisable spec and paint are nice options to have

Lows
  • Squidlock is a little messy on the bars

  • Super-racey rubber doesn't always inspire confidence
