Bike accessory saddle mount system

This versatile accessory mounting system lets you securely attach a range of essentials to your bike saddle, including rear lights, CO₂ canisters and inflators, and action cameras.

 

The mount clamps neatly to the rear of the saddle rails, ensuring it won’t interfere with saddle positioning or adjustment and is compatible with dropper posts.

 

A wide selection of add-on mounts allows you to customise the setup to suit your exact needs. All connections use a standard M5 screw and retained nut, with the option to use a GoPro-style screw for quick, tool-free adjustments and easy swapping between mount types.

 

The system has mounts for any rear lights that use the Garmin mini type connector, commonly found on Magicshine and Rockbross lights, amongst others.

For each light mount, there are two variants denoted as either H (horizontal) or V (vertical).  Please choose the correct variant for you light. As per the image below, the horizontal version suits lights where the tabs run horizontally when installed like the light on the left, and the vertical version suits lights where the tabs run vertically when installed like the light on the right.

To complete assembly, you will require standard M5 nuts and M5 x 20mm screws, for the CO2 canister and light mount, there is some super-glue required as this is a two-part assembly.  A gopro screw can be used an an option for mounting the adaptors to the main clamp.
 

All of these mounts have been real world tested using PETG.  PETG is recommended as a minimum, or use another engineering filament.  PLA is not recommended as the brittle nature may result in failure on bumps or rough terrain.

For the action camera mount, I would always recommend using a secondary tether to the seat rails, just in case.
