The Fiido C21 E-Gravel & City E-Bike is a lightweight electric bike designed for riders who want efficient performance across both urban roads and gravel paths. Combining a 250W rear hub motor, advanced torque-sensor pedal-assist, and a sleek aluminium frame, the C21 delivers smooth, natural assistance while maintaining the responsive feel of a traditional gravel bike.
With its slim design, integrated battery and reliable Shimano drivetrain, the C21 balances practicality with modern e-bike technology for everyday riding and longer leisure journeys.
The efficient 250W rear hub motor provides smooth pedal assistance up to 25 km/h (15.5 mph). A built-in torque sensor measures pedalling force and adjusts motor output instantly, delivering a natural riding experience and improved efficiency.
The C21 uses a lightweight 36V lithium battery integrated into the frame, offering an estimated range of up to 80 km per charge under ideal riding conditions.
Narrow gravel-style tyres provide a balance between efficiency and traction, making the C21 suitable for paved roads, cycle routes and compact gravel paths. The rigid fork design helps keep weight low and pedalling efficient.
A minimalistic display interface allows riders to view key riding information, including battery level and assist mode. Integrated lighting improves visibility for riding in low-light environments.
The bike is equipped with hydraulic disc brakes to provide reliable stopping power in varying weather conditions. The lightweight aluminium alloy frame ensures durability while maintaining responsive handling.
The Fiido C21 integrates smart control capabilities through the Fiido mobile app, allowing riders to monitor ride data and manage bike settings.
Charging time is typically 4–5 hours using the supplied charger.
