Kona Unit

The Kona Unit is a versatile mountain bike that has captured the attention of riders since its introduction in 2008. Positioned as a single-speed mountain bike in Kona’s lineup, the Unit is known for its simplicity and durability. Unlike many modern mountain bikes that feature complex suspension systems and a myriad of gears, the Unit embraces a straightforward design ethos. This makes it particularly appealing to purists who appreciate the raw and unfettered connection between rider and trail. Over the years, the Unit has maintained its core design but has seen updates in materials and geometry to keep it relevant in the ever-evolving mountain biking scene.

Riding the Kona Unit on UK trails is a unique experience. Its single-speed setup demands a higher level of fitness and offers a more engaging ride, particularly on varied terrain. The lack of suspension requires riders to be more attentive and skilful in navigating rough trails. However, the steel frame, which is a staple of the Unit, provides a forgiving ride that smooths out the chatter without the need for rear suspension. This bike excels on the kind of undulating singletrack found in the forests of Wales or the South Downs. It’s not the bike for those seeking gnarly downhill runs, but for those who relish the challenge of technical climbs and descents, the Unit is a rewarding companion.

When compared to its rivals, the Kona Unit stands out for its unique blend of simplicity and solidness. Bikes like the Surly Karate Monkey or the Salsa Timberjack offer similar experiences but often come at a higher price point or with a different focus on versatility. The Unit’s standout feature is its commitment to the single-speed ethos, which sets it apart in a market saturated with multi-gear, full-suspension options. This doesn’t mean the Unit doesn’t have its limitations. It’s not as fast on the flats as a geared bike, nor as forgiving as a full-suspension model on the descents.

The used market for the Kona Unit is quite healthy, thanks to its cult following. Prices vary depending on the year and condition, with older models typically fetching between £300 and £600. The post-2015 models, which feature updated geometry and tubeless-ready rims, are particularly sought after and can command prices closer to £800. Buyers will find the best value in models from around 2015 to 2019, where the balance of modern updates and price is most favourable.

Potential buyers should be aware of a few quirks. The steel frame, while durable, is heavier than aluminium counterparts, and rust can be an issue if the bike is not properly maintained. Additionally, the single-speed setup means there’s no hiding from climbs, so it’s important to ensure the gearing suits your local terrain. Check for signs of wear on the chain and cog, as they take more stress compared to multi-speed setups.

What it's like to ride

Riding the Kona Unit on UK trails is a refreshing change from the norm. The single-speed setup requires physical commitment and adds a layer of challenge to your rides, especially on the rolling hills and wooded paths common across the country. The steel frame absorbs much of the trail's chatter, offering a surprisingly smooth ride despite the lack of suspension. It's a bike that encourages skill development, as you'll need to pick your lines carefully and maintain momentum on climbs.

Who it's for

The Kona Unit is perfect for mountain bikers who appreciate simplicity and a direct connection to the trail. It suits riders who enjoy a challenge and those looking to improve their skills without the distraction of modern drivetrain complexities.

Models from 2015 to 2019 provide the best value, offering modern geometry improvements and tubeless-ready rims at a reasonable price.
