Riding Experience

My experience riding the BMC Kaius 01 THREE is that this gravel bike is extremely lightweight, and its geometry is excellent. My overall riding position is well-suited for standard gravel riding.

To test it out, I packed the BMC Kaius 01 THREE and headed to the gravel roads from Logan Mill to Sugarloaf to Magnolia. These roads were covered in gravel and had minimal car traffic, offering stunning views of the Rocky Mountains. I planned to complete a loop ride along the perimeter.


The climbing performance of the BMC Kaius 01 THREE is indeed excellent. The carbon fiber layup and gravel-specific geometry ensure stiffness, making my pedaling feel more direct during climbs. The bike’s robust integration provides quick-forward propulsion.

Furthermore, when the inclines become steep, the SRAM RIVAL eTap AXS 2×11-speed drivetrain, with its ample gear ratios, allows me to maintain a light and efficient pedaling feel, minimizing energy consumption.

Finally, the Pirelli Cinturato Gravel H – 40mm gravel tires used on the BMC Kaius 01 THREE offer excellent traction. Combined with efficient power transfer, climbing becomes more manageable, with no slipping, allowing for faster ascents.

In summary, the climbing performance of the BMC Kaius 01 THREE is excellent, primarily due to its lightweight design, reducing the energy expended.


The BMC Kaius 01 THREE excels in providing an outstanding descending experience. First, the carbon fiber frame and fork absorb road vibrations, reducing the bumpiness of my descent. The 700c large wheels and generously wide tires offer robust performance, reducing the risk of tire punctures. I can maintain a smoother descent, with the bike’s stability being excellent.

On the downhill curves, the SRAM Rival eTap AXS HRD hydraulic disc brakes, along with SRAM Paceline Rotors 160/160mm brake discs, provide unquestionably reliable braking. I can control my speed freely through braking. Additionally, the shorter handlebars make my handling more responsive and agile in the curves.

In conclusion, the descending performance of the BMC Kaius 01 THREE is excellent, ensuring a stable descent posture and a sufficiently high speed.


The BMC Kaius 01 THREE features an unprecedented carbon fiber frame and fork with advanced carbon fiber layup, ensuring frame rigidity. This translates to a more direct feeling of power transfer while also absorbing road vibrations for a more comfortable ride.

Additionally, there are 6 frame sizes to choose from, offering a wide range of sizing options suitable for a broad spectrum of rider heights.

The integrated full internal cable routing design enhances the bike’s aesthetics, making it appear neater. It simplifies routine cleaning and reduces air resistance for improved aerodynamics.

The SRAM RIVAL eTap AXS drivetrain and braking components offer fast and precise shifting with efficient power transfer. The reliable hydraulic disc brakes provide direct and powerful braking performance in all weather conditions.


Other Versions

The BMC Kaius 01 THREE features a lightweight carbon fiber frame and excellent geometry, making it well-equipped to handle off-road unpaved surfaces. For riders with a more generous budget, there’s a top-tier version available.

BMC Kaius 01 ONE
