On this page, you will find specification sheets for previous Omnium models and iterations.
Before the introduction of the WiFi and Classic models, there was no standardisation across frames, and each production batch could include small, undocumented changes. As a result, some batches may not be shown in these charts. If your bike does not fall into any of the categories listed below, please get in touch and we will do our best to locate the relevant frame specifications for you.
Please note that the reference names used here are simply nicknames from our workshop, created to help identify these early generations. They are not official designations, and not all variations are represented.

The rack for the V3.1 Mini does not have the same mounting interface and will not be able to attach to the Mini V3 or other older Minis.
