VIVI Bike Derailleur Bike Rear Derailleurs

A crisp click on a steep climb tells the rider the drivetrain is in harmony — that’s the VIVI Rear Derailleur at work.

Engineered to deliver consistent, precise shifts under the higher loads of electric-assist riding, this derailleur keeps cadence smooth on steep hills and frequent stop-start city trips. Short, dependable throws minimize chain bounce while a long-cage profile manages wide-range cassettes common on e-bikes.

Features

• Compatible with most 9/10/11-speed drivetrains and wide-range cassettes.
• Long-cage design for reliable chain tension under high torque.
• Reinforced alloy body with corrosion-resistant finish for daily use.
• Precision pulley alignment for quieter, crisper gear changes.
• Bolt-on installation replaces many common rear derailleurs with minimal adjustment.

Ideal for commuters, cargo riders, and touring e-bikers who demand low-maintenance dependability, this VIVI derailleur balances performance, durability, and value for real-world electric bike use.
