Fiido C21 E-Gravel E-Bike for Urban and Gravel Riding
Fiido C21 E-Gravel E-Bike for Urban and Gravel Riding
Lightweight assistance for city streets and gravel routes
The Fiido C21 combines a slim aluminium frame with torque-sensing pedal assistance. Its 250W rear hub motor responds to your effort, while nine-speed gearing helps you choose a comfortable cadence on urban journeys and lighter gravel routes.
At approximately 17.5kg, the C21 keeps the feel of a conventional bicycle. Hydraulic disc brakes, 700c tyres and an integrated 208.8Wh battery complete a practical package for riders who value a lighter e-bike.
Designed for everyday riding
- Responsive assistance: a torque sensor adjusts support to how firmly you pedal.
- Lighter handling: the approximately 17.5kg build is easier to manoeuvre than heavier touring models.
- Flexible gearing: nine speeds help you adapt your pedalling to climbs and flatter sections.
- Clean frame design: the integrated battery keeps the bike’s profile uncluttered.

Frequently Asked Questions
Who is the C21 best suited to?
Riders looking for a relatively light e-bike for commuting, leisure rides and lighter gravel routes. Its conventional frame and 700c wheels suit people who do not need a folding or cargo bike.
How does the assistance respond?
The torque sensor measures your pedalling effort and adjusts motor support as you ride. The nine-speed drivetrain lets you change your own gearing independently.
Is the battery integrated into the frame?
Yes. The C21 uses a 36V 5.8Ah battery integrated into the frame, with a capacity of 208.8Wh.
How can I get the most range from the C21?
Use lower assistance on easier sections, keep tyres at the correct pressure and maintain a steady pace. Hills, cold weather and heavier loads use more battery power.
