Evil Bikes is a boutique brand with a small lineup of MTB and gravel bikes that scream innovation, performance, and a lack of regard for tradition and boundaries. 

Evil Bikes is a specialty bike manufacturer based in Seattle, Washington. The company was founded in 2009 as a direct-to-consumer business that aimed to challenge the mountain biking standards of the time.

Though Evil started out rough, with broken frames and supply chain issues, it went on to become one of the most revered brands in the MTB world.

Evil bikes live up to their name—they’re low, slack, mean, and fun machines. What makes this possible is the groundbreaking carbon frames built around the DELTA suspension system, resulting in bikes that lead the way in design, geometry, and performance trends.


The Rowdy and Uncertain Beginnings

Evil Bikes’ history is short but turbulent, checkered with massive successes and even bigger setbacks.

When Kevin Walsh, the owner and lead designer, decided to establish Evil Bikes, he envisioned a brand that would do things differently, experiment, and bring the wow factor back into mountain biking.

Evil’s journey began in 2009 in Seattle, Washington with a full-suspension bike called the Revolt. The bike was a huge success and a huge failure as it had recurring issues with cracked frames.

A few rough years down the line, Evil learned from its mistakes and struck gold with The Following 29er in 2014. This was (and continues to be) the trail bike that completely changed the MTB standards by reviving 29″ wheels and introducing the low, long, and slack geometry. Everyone who rode it loved it and many even dubbed it the Mountain Bike of the Decade.

Today, Evil Bikes continues to receive accolades that are earned on pure merits with XC, Trail, Gravel, and Enduro bikes such as the Following, Offering, Wreckoning, Chamois Hagar, and the likes.

Evil Bikes Technology

Each Evil bike is unique and has an individual list of features and characteristics. However, there are a few key technologies that are carried across the range. These are the super-lightweight carbon frames, DELTA suspension system, and the Flip Chip adjustment.

The DELTA system was conceived by Dave Weagle to produce complex leverage rate curves that can be used to adjust the suspension for different trail conditions.

The DELTA system uses compact links that produce a lot of angle and velocity change through the travel, which allows riders to fine-tune the suspension performance.

Additionally, the DELTA suspension system is equipped with the Flip Chip technology. It lets you alter the frame geometry without changing the bike’s leverage curves. By flipping the chip, you will change the head tube angle and the bottom bracket height. Therefore, it’s like having an “Evil” and “Evil-er” setting on your bike.
