TAIYO YUDEN’s Unique
Next-generation
Regenerative Electric
Assist System
FEREMO™*

When braking or coasting, the front wheel motor generates electricity while smoothly controlling the speed. This means efficiently recovering and reusing kinetic energy.
This groundbreaking system allows you to enjoy worry-free rides for expended periods without the need for frequent battery recharges.

System Features

The benefits of electric bicycles equipped with FEREMO™
include the following.

Energy is not wasted,
but used to charge
the
battery instead.

When you brake or stop pedaling, the motor generates electricity and charges the battery. The multifunctional indicator shows the amount of electricity generated. You will feel good riding the bicycle while knowing that you are helping the planet.

Circulating energy
to keep on moving.

Using the charged electricity, the system provides powerful assistance when pedaling uphill. It is fun to look at the multifunctional indicator that shows the amount of electricity generated and calories burned.

Anyone can ride long
distances
for many hours
safely and securely.

Frequent power generation allows you to ride for long distances without worrying about remaining battery life.
Also, the motor works like an engine brake while generating power on downhill, providing greater safety.

Reducing troublesome
charging of heavy battery

The system charges the battery while riding, which reduces battery consumption and leads to less charging frequency. It reduces the stress of charging the battery and the burden of detaching a big, heavy battery and bringing it home.

Equipment and
Functions

FEREMO™ is a system that saves energy and is friendly to the riders’ health.
Its equipment and functions include the following.

  • Multifunctional indicator

    The indicator on the handlebar shows not only remaining battery life, speed, and distance traveled, but also the amount of electricity generated and calories burned. It allows you see your contribution to the environment and health, improving the user experience.

  • Highly efficient
    regenerative motor

    The front drive hub motor allows highly efficient regeneration (energy reuse).

  • Energy-saving controller

    The controller efficiently controls the motor, as well as charge and discharge, for further energy saving.

  • High-performance battery

    Together with the controller, the high-performance lithium-ion battery allows energy saving.

  • Rapid charger for FEREMO™​

    Designed specifically for lithium-ion batteries, the charger supports rapid charging.
