Orbea Onna upgrades an entry-level hardtail mountain bike for adults and children

Orbea have released the Onna hardtail mountain bike described as a fun and efficient bike to discover your passion for mountain biking or start exploring XC. Available in an affordable price range, the aim is to entice the contingent of trail-curious cyclists to finally press send on a one-track-ready vehicle on which to expand their off-road horizons. Here’s a quick overview.

Orbea Onna

2022 Orbea Onna Alloy Hardtail Mountain Bike Model 10 Blue Frame

The Orbea Onna is a 100mm-travel aluminum hardtail mountain bike designed for all genders, although the word “Onna” is one of many ways to refer to women in Japanese. For Orbea, the original “Onna” was actually a revolver that the brand made around 1840. Nomenclature aside, the Onna is now reincarnated as a different weapon, an ATV designed to deliver nothing but good times.

It enters the Orbea range as an entry-level bike, aimed at riders new to mountain biking, who may be thinking of getting off the asphalt onto trails for the very first time. It’s a modern iteration of the bike on which most of us who consider ourselves mountain bikers discovered our love for the sport. Keep this in mind when taking a look at the geometric figures below.

The Onna is by far Orbea’s most affordable mountain bike, with all models well below the price of their more aggressively-geometry Laufey. Pricing for the complete bike starts at £629 ($799 USD), pitting the Onna against the Trek competitor Marlin, a comparable entry-level hardtail mountain bike that’s common in UK trail centres.

Although the cheaper model is more expensive than the Marlin (which costs £475), it trumps in terms of frame detail with a tapered head tube, unlike the straight head tube seen on the Marlin. This limits the use of the Marlin to straight-steerer only forks, which tend to be heavier with less adjustability than forks with a tapered steerer tube. That said, you’ll have to part with £999 to get the Onna 20 before you get an air-sprung fork; the cheaper Onna 30, Onna 40 and Onna 50 all have an SR Suntour fork with a coil spring. The ability to upgrade to something higher end remains.

Orbea tells us that a tapered head tube is also stiffer, providing more control and precision when handling the bike.

The geometry and sizing recommendations for the Orbea Onna have been developed with a focus on providing a controlled, comfortable and efficient ride feel for riders somewhat unfamiliar with the bumpy and often unpredictable nature of singletrack. In terms of reach, it is significantly shorter compared to the vast majority of XC hardtails on the market, almost a size shift from what more experienced riders are familiar with.

Available in sizes XS-XL, the Onna’s reach measurement starts at 365mm and peaks at 468mm in XL. It gets a 68.5° head angle and a 74.5° seat tube angle. Wheel size depends on frame size; the XS bike comes with a 27.5-inch wheelset only, while riders suited to the smaller frame have a choice of 27.5-inch and 29-inch. The Medium to XL bikes all only work with 29 inch wheels.
