The kit that lets you fit the Sur-Ron Ultra Bee front brake system to a Light Bee X, Light Bee L1e or 79BIKE Falcon Pro. It contains a CNC adapter in aerospace 7075 aluminium and a 240 mm disc, 3.3 mm thick.
Said plainly: this is the mechanical part of the conversion — mounting and disc. The master cylinder, caliper with pads and line are in the complete Ultra Bee front brake. Without them this kit will not stop the machine. Do the front first — under braking the front wheel carries most of the load.
What to order
| What you have | What you order | Why |
|---|---|---|
| Light Bee X / L1e or 79BIKE Falcon Pro | This kit + complete Ultra Bee front brake | The kit gives mounting and the 240 mm disc. The hydraulics come with the brake assembly. |
| You already removed a front system from an Ultra Bee | This kit alone | What you are missing is exactly the adapter and the disc for Light Bee geometry. |
| You are doing both axles | This kit + rear conversion + both brake assemblies | Four items, one result: the full Ultra Bee brake system on a Light Bee. |
The most common mistake: ordering the conversion kit alone expecting a working brake. This is not a brake — it is adapter and disc. The hydraulics are linked in the tile below.

- A disc guard is not part of this kit.
Frequently asked questions
Is this a complete brake?
No. It is adapter and disc — the mechanical part of the conversion. Master cylinder, caliper and line are in the complete Ultra Bee front brake.
Front or rear first?
Front. Under braking the front wheel carries most of the load, so the gain is immediate.
Will the 240 mm disc work with the stock Light Bee caliper?
No. The larger disc needs this adapter and an Ultra Bee caliper.
Is a disc guard included?
No. The manufacturer does not include one in the front conversion. The rear version does include a guard.
Does it fit the 79BIKE Falcon Pro?
Yes — the manufacturer lists that model alongside Light Bee X and L1e.
Without this the conversion does not work
Not sure whether you also need the brake assembly?
Tell us what you already have stripped down. We will say exactly what is missing for a working system.
