Product Description

Eunorau | Single Speed Cassette Conversion Kit

Overview

A compact conversion kit that turns a multi-gear cassette hub into a reliable single-speed drive. Designed for Eunorau fat and off-road e-bikes, it simplifies the drivetrain for hunting, trail riding, or low-maintenance use.

Benefits

  • Makes your bike easier to maintain — fewer parts to clean, adjust, or replace.
  • Improves reliability in mud, snow, and rough terrain by removing the derailleur and multiple sprockets.
  • Quieter, smoother drivetrain for a less distracting ride.
  • Quick to install so you can switch to single-speed when you need it and go back later if desired.
  • Allows you to set a consistent, purpose-built gear for hunting or off-road performance.

Features

  • Converts most multi-geared Eunorau e-bikes to a single-speed drivetrain.
  • Includes a 32T single-speed cog for a stable gear choice.
  • Comes with four spacers to adjust chainline and achieve proper alignment.
  • Includes a single-speed chain guide to keep chain retention reliable.
  • Compatible with hubs that previously ran 8, 9, 10, 11, or 12-speed cassettes.
  • Quiet, simple, and smooth operation once installed.
  • Compatible Eunorau models:
    • Specter-S
    • Defender-S
    • FAT-HS
    • Fat-HD
    • Fat-HD1.0 Pro
