Surron Ultra Bee big brake kit, stainless wave rotor, dual NIBBI calipers and black anodized mounting bracket

FactoryZ | Ultra Bee Brakes

We were tired of mountain bike brakes. We ran every caliper, master cylinder and rotor on the market trying to find a setup that could take our bikes past their limits. None of it held up, so we built our own.

FactoryZ Ultra Bee brake kits put the Ultra Bee caliper, a real dirt bike brake, on the Surron Light Bee, Talaria X3 / MX3 / MX4, Eride Pro SS and more. Since we released them in early 2025, we’ve sold over 3,000 pairs.

We test them where most parts never go: a full bike submerged in a pond to prove they hold under water, and 60 MPH power wheelies on the track. Ultra Bee brake kits are built past what E-moto sized bikes were ever meant to handle.

Based in Wisconsin. Every order ships from our 6,500 sq ft USA warehouse.
