Design and Build quality
The Fiido C21 is an exciting addition to the Fiido lineup, being the first-ever Fiido E-Gravel bike. With its versatile features and reliable components, the C21 is designed to offer a smooth and enjoyable riding experience on various terrains.
One of the notable features of the C21 is its wide-range 11-32 9-speed cassette. This allows riders to easily tackle different inclines and maintain an optimal pedaling cadence. The L-Twoo 9-speed derailleur and trigger shifter ensure precise and smooth gear shifting, enabling riders to swiftly transition between gears without any hassle.
To ensure reliable and efficient braking performance, the C21 is equipped with Tektro hydraulic brakes. These brakes offer excellent stopping power and modulation, allowing riders to have full control over their speed, especially during off-road or gravel adventures.
The CST Tirent 700x40c gravel-specific tires are another standout feature of the Fiido C21. Weighing in at 510g, these tires strike a balance between durability and weight, providing a comfortable and stable ride on gravel surfaces. They offer excellent traction and grip, allowing riders to confidently navigate through loose or uneven terrain.
The C21 also comes with a range of accessories that enhance its functionality and convenience. The mudguards help protect riders from dirt and mud splashes, keeping them clean and dry even in wet conditions. The kickstand offers practicality when parking the bike, ensuring stability and ease of use. The front and rear lights are essential for safety, allowing riders to be visible in low-light or nighttime riding situations.
The Fiido C21 comes in medium (5’2″-5’7″) and large (5’6″-6’4″) sizes in terms of size selections. This range allows for a wide range of rider heights, guaranteeing a cozy and ergonomic fit for people of various heights.
The Fiido C21 comes with several innovative design elements that enhance its functionality and usability. One of these features is the clear and waterproof central display. Positioned at the center of the handlebars, this display provides riders with essential information such as speed, battery level, and distance traveled. The clear design ensures visibility even in bright sunlight, while its waterproof nature protects it from the elements, making it suitable for various weather conditions.
Another design aspect that adds to the overall aesthetic and functionality of the C21 is the hidden wiring. The wires and cables are neatly integrated into the frame, giving the bike a clean and streamlined appearance. This not only enhances the visual appeal but also reduces the risk of any wires getting snagged or damaged during rides. The hidden wiring also contributes to the bike’s durability and longevity.
Weighing in at just 18kg, the Fiido C21 is a lightweight e-gravel bike. This lightweight design makes it easy to maneuver and control, whether you’re riding on rough terrain or navigating through urban streets. The reduced weight also contributes to the bike’s efficiency and range, allowing riders to cover longer distances with less effort.
Despite its lightweight construction, the Fiido C21 has an impressive maximum load capacity of 120kg. This ensures that the bike can accommodate a wide range of riders, including those who may carry additional gear or equipment. The robust frame and components of the C21 contribute to its high load-bearing capacity, ensuring stability and reliability even with heavier riders or cargo.
Motor and Driving

The app support adds a modern touch to the riding experience and allows riders to customize their settings on the go.
The Fiido C21 features torque-sensing pedal assist, which provides a natural and intuitive riding experience. The pedal assist system detects the rider’s pedaling force and adjusts the electric assistance accordingly. This ensures a seamless transition between human power and electric assistance, making the ride feel more organic and engaging.
The smooth bearings integrated into the C21’s design contribute to its overall ride quality. These bearings reduce friction and provide a smooth rotation, resulting in a more efficient and comfortable ride. The smooth operation of the bearings enhances the bike’s performance and longevity, allowing riders to enjoy a reliable and low-maintenance experience.
The C21’s tires are designed to be large enough to absorb road surface imperfections. This feature ensures a smoother and more comfortable ride, especially when encountering uneven or rough surfaces. The tires provide improved traction and stability, allowing riders to confidently navigate through various road conditions.
The Fiido C21 takes smart riding to the next level with its intelligent proximity start feature. This innovative technology allows the bike to detect the presence of the rider and automatically activates when it senses proximity. This means that riders don’t need to manually power on the bike or press any buttons to start their journey. With the intelligent proximity start, the C21 is always ready to go whenever you are.
Fiido’s Exclusive Algorithm for Torque Sensor System is another remarkable feature of the C21. This advanced algorithm is designed to accurately measure and interpret the rider’s pedaling force and translate it into the appropriate level of electric assistance. The torque sensor system ensures a responsive and natural riding experience, providing electric assistance precisely when needed. Whether you’re cruising on flat terrain or climbing steep hills, the C21’s torque sensor system delivers the optimal amount of power to complement your cycling efforts.
