Steering Motor
The steering motor used is a Maxon DCX 32 L 24V.
The motor is connected to a planetary gearbox of type Maxon GPX 32 with a reduction of 111:1.
The output shaft of the motor/gearbox combination has a diameter of 10 mm. The bike stem has a diameter of 34.56 mm.
Mounting
We designed a custom mount that allows the motor and gearbox to be mounted parallel to the steering axis. The shaft of the motor and the bike stem have belt pulleys attached and they are linked with a toothed belt.
Magnets for Hall Sensor
There are five magnets equally spaced around the circumference of the rear wheel. The wheel diameter was measured to be 0.695 m.
