Fiido E-Gravel C21 Electric Bike
The Fiido E-Gravel C21 is designed to deliver the perfect balance between performance, style, and comfort for modern city commuters and adventure seekers. Crafted with a sleek 700C aluminum alloy integrated battery urban gravel frame, this e-bike stands out for its lightweight build, exceptional strength, and seamless design integration. Weighing just 38.6 lbs (17.5 kg), it offers the nimbleness of a traditional bicycle with the powerful assistance of an advanced electric system, making it ideal for daily rides, fitness journeys, and weekend explorations.
Powerful and Efficient Electric System
At the heart of the C21 lies the Mivice M080 250W drive unit, engineered to deliver smooth and efficient power output. Paired with the DMEGC 208.8Wh battery, it offers reliable pedal assistance for long-distance urban commuting or light trail rides. The integrated design keeps the battery well-protected while maintaining a clean and minimal aesthetic. The 36V2A charger ensures quick and efficient recharging, minimizing downtime between rides. Riders can easily monitor their performance and system status via a 2.4-inch LCD display, providing real-time information such as speed, distance, and battery level.
Precision Drivetrain and Smooth Control
The Fiido C21 features a 9-speed L-TWOO drivetrain for precise and responsive shifting. The L-TWOO RD-5009-M rear derailleur and SL-5009-9S shifters ensure quick gear transitions, allowing riders to adapt effortlessly to varying terrains and riding conditions. The KMC X9 chain and aluminum alloy 52T crank enhance durability and provide efficient power transfer with every pedal stroke. Complementing this setup, the L-TWOO 9S (11–32T) rear cogs allow for versatile gearing options, making climbs easier and descents smoother. The Mivice S200 torque sensor ensures that power delivery feels natural, matching motor assistance to the rider’s pedaling effort.
Superior Braking and Safety
Safety is paramount in the C21’s design. The TEKTRO HD-M275 hydraulic disc brakes offer excellent stopping power and control in all weather conditions. Paired with TEKTRO HD-M275 brake levers, riders can expect smooth and consistent braking performance on both urban roads and gravel paths. Whether navigating through city traffic or descending steep slopes, the C21 ensures reliable control and confidence.
Durable Wheels and Reliable Tires
Built for stability and comfort, the Fiido C21 rides on aluminum alloy double-layer rims laced with stainless steel spokes and brass nipples, ensuring strength and durability even on rough surfaces. The aluminum alloy double-bearing barrel axle hub (15mm barrel diameter) enhances rotational smoothness and structural rigidity. Fitted with CST/KENDA 27.6×1.57 tires, the bike delivers excellent grip and low rolling resistance, making it equally suitable for paved roads and light off-road tracks.
Comfort-Oriented Design and Components
Every component of the Fiido C21 is designed for rider comfort and ergonomics. The aluminum alloy handlebar (640mm length, 31.8mm max diameter) provides stability and control, while the aluminum alloy stem ensures a secure connection to the front end. TPR non-slip grips (130mm length) offer excellent tactile comfort during long rides. The VELO vacuum full-fit saddle is designed to support the rider’s posture and absorb shocks for enhanced comfort. The aluminum alloy clamp head seatpost (M-300mm/L-350mm, 30.9mm diameter) allows for easy height adjustment and sturdy seating.
Stylish, Lightweight, and Practical
The Fiido E-Gravel C21 embodies the perfect blend of urban style and practical performance. With a payload capacity of 264.6 lbs (120 kg), it accommodates riders and cargo effortlessly. Its lightweight yet durable construction makes it easy to carry upstairs or load into a car rack. The integration of advanced technology, premium materials, and refined geometry ensures a superior riding experience that caters to both daily commuters and weekend adventurers.
