EUNORAU 2-Piston Hydraulic Disc Brake Sensor Set with 180MM Brake Rotors for BBS/ENA motor kits&eBike Upgrade

Midway down a wet, winding descent, a dependable stop matters more than horsepower.

Overview

The EUNORAU 2‑Piston Hydraulic Disc Brake Sensor Set with 180 mm rotors brings precise braking control and motor-cut safety to BBS/ENA mid-drive kits and many e‑bike upgrades. Two‑piston calipers deliver linear modulation and strong bite, while 180 mm rotors add leverage and heat capacity for longer descents and heavier loads. The integrated brake sensor ensures the motor cuts instantly when braking, improving safety in traffic and on steep trails.

Practical benefits

This kit is suited for commuter, cargo and trail e‑bikes where predictable stopping, low maintenance and straightforward installation are priorities. Sealed hydraulics resist contamination; rotor size balances power and clearance.

Highlights

• 2‑piston hydraulic calipers for consistent modulation
• 180 mm rotors for increased stopping torque and heat dissipation
• Integrated brake sensor for instant motor cut-off
• Sealed construction to reduce maintenance and improve longevity
• Bolt-on compatibility with BBS/ENA mid-drive kits for straightforward upgrades

A practical, safety-focused upgrade that gives riders confidence under load, in wet conditions, and on extended descents.
