Electric bike Fiido C21 Gravel & City

Minimalist design, exceptional lightness, and complete freedom on city streets and gravel paths.


Fiido C21

Benefits icon Who is this electric bike most suitable for?

The Fiido C21 is created for modern urban cyclists and adventurers looking for a "Gravel" e-bike without compromising on weight and aesthetics. If you want a bike that doesn't even look like an electric one at first glance, but still offers you top-tier assistance in conquering hills, this is your ideal choice.

With its exceptionally low weight (only 17.5 kg) and fully integrated wiring, it is perfect for those who frequently carry their bike up stairs or store it in an apartment. Whether you are commuting to work in the city center or exploring gravel paths on the weekend, the C21 offers precise handling and superior agility.

Fiido C21

Weight icon Flawless design and featherweight

Forget about bulky and heavy electric bikes. The frame of the Fiido C21 model is made of high-quality 700C aluminum alloy, into which the battery is seamlessly integrated. This engineering achievement keeps the bike's lines clean and minimalist while ensuring the structural rigidity needed for gravel terrains.

With a total weight of only 17.5 kg (38.6 lbs), this bike sets new standards in its class. The minimalist approach continues with the wiring, which is completely hidden inside the frame, not only improving aesthetics but also simplifying maintenance and protecting the cables from external influences and damage.

Fiido C21

Motor icon Advanced Mivice drive with torque sensor

The heart of the bike is the silent Mivice M080 brushless motor with 250 W of power, which provides assistance up to 25 km/h (limited) in accordance with road regulations. A special feature of this motor is its "low-resistance" technology, meaning you can easily ride the bike entirely analog when the battery is empty or when you do not need assistance.

The biggest advantage, however, is the top-tier Mivice S200 torque sensor. Unlike cheaper cadence sensors, the torque sensor measures the actual force you apply to the pedals. The result is an extremely smooth, natural, and responsive assistance that adjusts to your riding style and terrain incline in milliseconds.

Fiido C21

Battery icon Integrated battery and optimized range

Hidden in the slim lower part of the frame is a powerful battery with DMEGC cells (208.8 Wh). Despite the smaller capacity, which contributes to the bike's low weight, the highly efficient motor and precise torque sensor ensure impressive autonomy.

When using ECO mode and under ideal conditions (75 kg rider, flat terrain, 32 °C), the bike achieves up to an incredible 100 km (62.14 miles) of assistance. There are 5 levels of assistance available: from ECO (100 km) to the most powerful Turbo+ mode, which will provide you with up to 34.5 km of range even during the most strenuous efforts. A reliable 36 V 2 A charger is included.

Fiido C21

Brakes icon Uncompromising braking power and grip

Safe stopping in all weather conditions and on all terrains is ensured by top-tier TEKTRO HD-M275 hydraulic disc brakes. They are equipped with precise levers from the same manufacturer, ensuring exceptional modulation and short braking distances with minimal effort on the lever.

Contact with the ground is provided by CST/KENDA 700*40C tires (dimension 27.6" x 1.57"). These are "knobby" tires with puncture-proof protection, offering low rolling resistance on asphalt while providing stable and reliable grip on loose gravel and forest paths.

Fiido C21

Gears icon Precise 9-speed derailleur

Because the Fiido C21 is designed for varied terrain and climbing hills, it is equipped with a reliable 9-speed L-TWOO shifting system. The L-TWOO RD-5009-M rear derailleur works in perfect harmony with the SL-5009-9S shifters, ensuring fast and quiet shifting.

The drivetrain is complemented by a large aluminum front crankset with 52 teeth (52T), a robust KMC X9 chain, and a wide-range 11-32T rear cassette. This combination of ratios allows you to maintain an optimal cadence both when riding fast on flat ground and when climbing steep gravel hills.

Fiido C21

Display icon HD color display and complete weather protection

An extremely bright 2.4-inch HD color LCD display is mounted in the center of the handlebars. Whether you are cycling under the strong summer sun or on a cloudy, rainy day, the data on speed, range, and assistance level will always be crystal clear and readable.

The entire bike boasts an IP54 protection standard. This means that all vital electronic parts (display, motor, sensors, wiring, and battery) are completely protected against dust ingress and water spray from all directions. Your bike is ready for riding through puddles and in the rain.

Fiido C21

Modes icon Ergonomics, comfort, and perfect fit

Because we know that correct geometry is key, the Fiido C21 is available in three frame sizes (M, L, and XL), covering riders from 160 cm to 205 cm in height. The frame withstands high loads with a capacity of up to 120 kg (264 lbs).

For maximum comfort on longer rides, there is a top-tier VELO vacuum full-fit anatomical saddle, mounted on an adjustable aluminum seat post (diameter 30.9 mm). The 640 mm long handlebars are equipped with 130 mm non-slip TPR grips, which reduce hand fatigue and ensure firm control over the bike.
