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.
