2. Method
The hardware used consists of four devices:
1. Inertial sensors to measure the vibrations.
2. Mounting brackets to attach these sensors to the bike
3. A GPS receiver
4. The bike
The inertial sensors were the ProMove2 wireless nodes from Inertia Technology [4]. These sensors
feature 8 degrees of freedom of motion information, a dedicated microcontroller and a separate System-
on-Chip (SoC) solution for low-power wireless networking. The network of sensor nodes is connected to
a notebook by the FastGateway. On the notebook the ProMove GUI software displays and logs all
acquired data for future processing.
The GPS receiver is a Garmin Edge 705. The receiver is configured to store all received data every
second. Automatic pausing is turned off, so the files are continuous in time.
The primary bike during testing was a Sensa Lombardia road bike. The secondary bike used during
the tests is a Simplon Gravity mountainbike. The major specifications of these bikes are printed in table 1.
