Stronger brakes for a SurRon Light Bee X that has gained power or rides steep trails. Choose a bigger 250 mm disc with its own caliper adapter for the stock brakes, or a complete Magura four-piston kit: MT5, MT5 eSTOP, MT5e HIGO or MT7 PRO, with Magura rotors, the QM 46 adapter and 8.R race pads to match.

Bigger discs for the stock brakes
The quickest gain is rotor size. The 250 mm front disc and 250 mm rear disc are larger than the factory discs and come with a caliper adapter and bolts, so the stock calipers stay and no frame or fork work is needed. Pads worn down? The OEM brake pads fit the factory calipers front and rear.
Magura brake kits
- Magura MT5: four-piston caliper and radial master cylinder with a 2-finger lever.
- MT5 eSTOP: the MT5 tuned for electric bikes, supplied with 8.S Sport pads.
- MT5e HIGO: a brake switch built into the lever that can cut motor power when you brake, if your controller supports it.
- MT7 PRO: the top of Magura's four-piston range, with a one-finger HC lever.
Each Magura kit covers one wheel, so order two for front and rear. Rotors and mounting adapters are sold separately: use a 203 mm or 220 mm Magura rotor, and the QM 46 adapter moves a 203 mm post mount caliper to a 220 mm rotor. The kits run on Magura mineral oil, never DOT fluid. For more bite later, the 8.R race pads fit MT5 and MT7 calipers.
Check before you order
The right mounting adapter depends on your fork and frame. If you are unsure, send a photo of the fork lowers and the rear brake mount to info@fabiride.com. Our Sur-Ron service centre in Kaunas also bleeds and services hydraulic brakes. In stock brake parts reach the carrier within 1 to 3 business days.
Frequently asked questions
Do Magura brakes fit the Sur-Ron Light Bee X?
Yes. The Magura MT5, MT5 eSTOP, MT5e and MT7 PRO are used as brake upgrades on the Light Bee. You need the right mounting adapter for your fork or frame and a 203 or 220 mm rotor, both sold separately.
Is one Magura kit enough for both wheels?
No. Each kit has one lever, one caliper and one hose, so a front and rear conversion needs two kits.
Which pads fit the stock Light Bee X brakes?
The OEM Sur-Ron brake pads. One set holds two pads for one caliper, and the same shape fits the front and rear factory calipers.
What does the HIGO switch on the MT5e do?
It closes a circuit when you pull the lever. That signal can cut motor power or switch on a brake light, as long as your controller supports it. Check your controller wiring before you order.
Which brake fluid do Magura brakes use?
Magura Royal Blood mineral oil. Never fill a Magura system with DOT fluid.
