Front Brake Assembly Surron Ultra Bee (Complete) – OEM Quality

Complete front brake kit for the Sur-Ron Ultra Bee, OEM quality. The front caliper, brake line and pump are not factory-connected — connect, fill and bleed them after purchase.

Attention: Unlike the rear brake kit, which comes as a ready, pre-connected set, this one is not factory-assembled. After purchase the user must connect the front caliper to the brake line and the front brake pump themselves.

SUR-RON ULTRA BEE

Ultra Bee front brake — complete assembly, OEM quality

Master cylinder, caliper with pads, line and fork adapter. The components are not factory-connected; after purchase they must be connected, filled with brake fluid and bled.

A complete front brake system for the Sur-Ron Ultra Bee in OEM class. This is not a factory-connected unit: after purchase you must connect the front caliper to the brake line and front brake pump, then fill the system with brake fluid and bleed it before fitting.

The front is what actually stops you — under braking it carries most of the load. That is why the same assembly is a common upgrade for the Sur-Ron Light Bee: the stock front brake fades on long descents and after a controller upgrade. For a Light Bee you need two items though — this one and the front conversion kit. The table below says exactly what to order.

What to order for your machine

Your machine	What you order	Why
Sur-Ron Ultra Bee	This assembly alone	The caliper adapter for the Ultra Bee fork leg is included. Bolt-on, no modification.
Sur-Ron Light Bee X / L1e	This assembly + front conversion kit	The conversion adds a CNC 7075 adapter and a 240 mm (3.3 mm) disc matched to Light Bee geometry.
79BIKE Falcon Pro	This assembly + front conversion kit	The conversion kit manufacturer lists the Falcon Pro as compatible.
You only need a disc or pads	Separate items in the shop	This assembly is the hydraulics: master cylinder, caliper, line, adapter. No disc inside.

The most common ordering mistake: a Light Bee owner buys this assembly on its own and then finds there is no way to mount the disc. A Light Bee X / L1e build needs two items — this one and the conversion kit (linked below).

What is in the box

Master cylinder

With an ergonomic handlebar lever, right-hand side. Ready to fit.

Caliper with pads

Pads are already installed — nothing extra to buy to get rolling.

Brake line

Correct length, increased pressure resistance.

Caliper adapter

Dedicated to the Sur-Ron Ultra Bee fork leg.

What is not included

Brake disc and disc guard. On an Ultra Bee you keep the factory ones. For a Light Bee conversion the 240 mm disc comes with the conversion kit — linked in the section below.

Before you order

On an Ultra Bee this is a direct fit — you need nothing else.
For a Light Bee X / L1e add the front conversion kit, otherwise the disc cannot be mounted.
The brake disc is not part of this set.
Doing both axles? The rear assembly is a separate item — linked below.

Frequently asked questions

Does it fit the Sur-Ron Light Bee?

Not directly. The adapter here is cut for the Ultra Bee fork leg. For a Light Bee X / L1e you add the front conversion kit — CNC 7075 adapter and a 240 mm disc, 3.3 mm thick. Only together do they make a working system.

Do I have to bleed it after fitting?

Yes. The kit is not factory-connected or filled. Connect the caliper to the line and pump, fill with brake fluid, bleed the system and check lever travel.

Is the disc included?

No. On an Ultra Bee the factory disc stays. For a Light Bee conversion the 240 mm disc comes with the conversion kit.

Front or rear first?

Front. Under braking the front wheel carries most of the load, so you feel the gain immediately. Add the rear as step two — it is the same type of assembly.

Can I get fitment confirmed before buying?

Yes. Send us your model and year and we will tell you exactly what to order.
