Controller Installation

Axon Phase — Sur-Ron Ultra Bee

Complete installation guide for fitting the Axon Phase controller to the Sur-Ron Ultra Bee. Please read all sections before beginning.

Do Not Rush

Allow yourself a good amount of time. Rushing causes pinched wires and incorrect fitment — both time-consuming to diagnose.

Correct Tools

A good set of allen / hex keys is essential. We will not accept responsibility for products or bolts damaged by incorrect tooling.

Safety First

You are installing an upgrade to an electric motorcycle. If you lack the experience, please seek a professional. Motorcycles can be dangerous when incorrectly installed.
