📐 Fitment & Installation Notes
⚠️ Important Fitment Notice:
This battery is designed primarily for small and medium sized bicycle frames. It can also be fitted to larger frames if required, but customers must ensure the battery base is mounted securely and safely.
The battery is removable, but it requires six bolts to be undone in order to remove it from the base.
This battery can also be installed inside a suitable triangle battery bag if preferred.
Securing the battery base correctly is crucial. Most pedal bikes only have two bottle cage mounting holes, however this battery base requires stronger support than standard bottle cage mounts.
We recommend using at least four mounting points where possible. If your frame does not have enough mounting holes, heavy-duty jubilee style clamps or equivalent secure mounting hardware should be used.
The battery base must be properly secured to ensure the battery remains safely attached to the bike during use.
