Fahrradcomputer Union 12

The Marwi Union-12 is a wired cycle computer with an extended range of basic and additional data fields. Thanks to the wired sensor connection, the measurement is stable and consistent, making it suitable for applications where wireless systems offer insufficient flexibility in wheel configuration.

This cycle computer provides up to twelve different functions, including current speed, average speed, maximum speed, trip distance, total distance (odometer), ride time, total ride time, speed comparison, clock (12/24 hour), calorie consumption, total calorie consumption and auto scan mode.

The Union-12 can be programmed for small wheel sizes, which is useful in applications where standard cycle computers have limitations, such as roller trainers and special vehicles. We use this model ourselves in the W900.255 roller bench. Installation is done with a bracket, sensor and cable connection; no wireless transmitters are required.

The display is easy to read while riding and shows the selected data clearly. The housing is water resistant and suitable for use in light rain. A practical solution where a wired system is preferred.
