Fiido D21 Folding Electric Bike

ACCURATE TORQUE SENSOR

The newly added torque sensor assesses the force put into the pedals, creating a significant improvement that achieves low latency, accuracy, and low maintenance. This addition improves the handling of the bike, making it much more intuitive and enjoyable to ride, while also making it safer.

250W HIGH-EFFICIENCY MOTOR

The 35nm 250W brushless geared motor tucked away in the 20-inch rear wheel provides incredible power even with its compact size and light weight, which is why it can easily overcome rugged and steep roads with extremely low energy consumption.

SPECIALLY DESIGNED BATTERY

The innovative battery is concealed in the seat tube, making the D21 nearly indistinguishable from an ordinary bicycle at first glance. Despite being so compact, the range can still reach 100KM under the electric moped mode. Furthermore, the battery is removable, meaning you can get it charged anywhere at any time.

PRAISEWORTHY BODY STRUCTURE

The innovative design of the integrated seatpost containing the battery and taillight reduces the number of components, improving efficiency to the full extent. In addition to the utilization of the aerospace-grade aluminum alloy frame, the model layout conforms to ergonomic design specifications, providing a comfortable riding experience with a height-adjustable leather seat. Furthermore, the self-weight of the D21 comes to a mere 12.9KG.
