FAQ

Which lever comes with the kit?
The stock Ultra Bee lever. The upgraded lever is a shorter, premium CNC metal lever with a laser-engraved Forged logo. It changes how the Ultra Bee brake feels, gives you more grip, and looks cleaner. The shorter style is better for wheelies and dirt riding.

How long does install take?
Most riders finish in 30–60 minutes. The brake comes pre-bled, so there's no bleeding.

Will Ultra Bee brakes fit my Talaria XXX?
Yes, with this kit. Choose the Talaria XXX / MX4 / MX3 option and it includes the mount and rotor the conversion needs.

Will it fit a Sur-Ron Light Bee X or E-Ride Pro?
Yes. Choose the Surron LBX / ERIDE / Segway option.

Do I need to bleed the brake?
No. The brake comes pre-bled.

Is this the front or rear brake?
This kit is a rear brake upgrade.

Installation is at your own risk.
