E-Motorcycle Brake Upgrade Guide
Choose by your bike and by wheel position. Front and rear rotors use different mounting patterns on the Sur-Ron Light Bee, so plan each end on its own.
Parts by Bike and Wheel
This table only lists fitment our product data states. If your bike is not here, ask us before you order.
| Part | Fit stated in our specs |
|---|---|
| EP8-II brake | Surron Light Bee |

EP8-II for the Light Bee
Our EP8-II has eight pistons, four 14mm and four 17mm, and runs on DOT 5.1 from a large reservoir. It is CNC cut from 7075-T6 aluminum with independent cooling fins.
It comes with the adapter and rotor guard for the Light Bee. Fitting it is a setup job rather than a simple swap, so read the product page first.
EP6-II for EMTB and E-Moto
Our EP6-II has six pistons, four 14mm and two 17mm, and also runs on DOT 5.1. It is tailored for EMTB and electric off-road motorcycles and is specified for 2.3mm to 3.0mm rotors.
The PM-PM+20 adapter is built in. Lever reach and leverage ratio are both adjustable.
Front Rotors Use 44mm BCD
Match both the size and the thickness to your brake and pads. HD-E is another 44mm option for e-moto front wheels.
| Rotor | Sizes | Build |
|---|---|---|
| Heavy duty front | 203 x 2.3mm, 223 x 2.3mm, 223 x 3.0mm | One-piece 420 stainless steel |
| X-Power front | 200, 203, 220 x 2.3mm | Floating, aluminum center |
Rear Rotors Use 54mm BCD
These two are for the rear wheel of the Sur-Ron Light Bee. Both have 3.0mm options.
| Rotor | Sizes | Build |
|---|---|---|
| Heavy duty rear | 203 x 2.3mm, 223 x 2.3mm, 220 x 3.0mm, 223 x 3.0mm | One-piece 420 stainless steel |
| X-Power rear | 223 x 2.3mm, 223 x 3.0mm | Floating, aluminum center |
Match Pads to the Rotor
On EP6+ brakes the pad size follows rotor thickness, so order them together. The brake pad guide has the full picture.
Adapter, Guard and Handguards
Our adapter and rotor guard is CNC cut from 7075 aluminum for fitting the EP8+ rear brake on the Surron Light Bee. If you ride a Talaria, ask us before you order, because coverage depends on the model. It comes in silver and black.
Prosafe handguards are made for mountain bikes, dirt bikes and e-bikes, with a 7075 aluminum clamp and a composite guard. A set weighs 108g.
