The FIT multifunction mount is designed to offer great flexibility in the use of your e-bike. It allows you to plan your routes on different types of devices – whether it's a smartphone, a Garmin, Sigma, or Wahoo on-board computer – which can then be securely mounted on the bike.

Installation is simple: simply remove the display from the e-bike and position the FIT Multi-Adapter in the FIT System's universal mount. Once attached, the device is held securely and all essential data remains perfectly readable at a glance while riding. The Multi-Adapter comes with several compatible inserts to ensure the attachment of different electronic devices.

Compatibility and technical requirements

Please note that the FIT e-bike system requires a compatible display to function. This can be either a FIT Display or a smartphone used as a display via the Drive Screen app . The lack of a display makes it impossible to use the system; a simple bike computer is no substitute for a FIT display.

When using a smartphone, it is imperative to use an SP Connect compatible mount or case to ensure secure installation on the multi-adapter.

Mounting details

The FIT Multi-Adapter mount attaches directly to standard FIT display mounts. A retaining screw, integrated into the multi-adapter, prevents the attached device from accidentally falling out. Installation is quick: simply place the display in place and insert the FIT Multi-Adapter into the bike's original mount.

The pack includes four adapter inserts , compatible with the following devices:

• SP Connect

• Wahoo

• Sigma GPS

• Sigma TL2450 WO
