About the VeloX

Each year, the team designs and builds a new VeloX that shaped around the athletes and incorporates the latest technological developments. By combining multiple engineering disciplines, the best result can be obtained.



Every year, the shell of the VeloX is redesigned from the ground up. Since women are generally smaller, a female athlete allows for a smaller shell, which results in less aerodynamic drag. In the latest VeloX, 80% of the airflow around the shell is laminar. One of the latest innovations that contributed to this was seamlessly integrating the backwheelfairing (the external cover at the backwheel) into the body. Furthermore, in the most recent design, there is no disturbance in the airflow on the tail, even at crosswinds. 


The structure is the skeleton of the bike. It connects everything and holds everything in place. Because of the structure, the VeloX is stiff and secure, even at high speeds. This is very important, because it will keep our athletes safe.

In the past year, a lot of improvements were made. The overall structure has been slimmed down to create a lighter and faster VeloX. The front frame was made stronger and more stable using single beams.



In order to be able to cycle over 120 km/h, a large gear ratio is needed. At these speeds, the wheels will rotate up to 14 times per pedal stroke. To realise this, a large gear ratio is necessary. This is achieved by splitting up the transmission into two steps. By increasing the gear ratio of the second smaller transmission, a smaller chainring (44 teeth vs. 100 teeth) was achieved, which makes the drivetrain more efficient.

User interface

The user interface functions as the eyes of the athlete. Because there are no windows in the VeloX, a camera is used that will show the road on two screens inside the VeloX. On these screens, the athlete also gets live feedback on speed, power output and predicted performance. The data is also sent back to the coaches, who can speak to the athlete through an integrated headset system during the race. This communication with the coach is essential for the performance of the athlete.
