Accurate Torque Sensor
Complementing this with a torque sensor to sense the force put into the pedals is a significant improvement, which can achieve low latency, accuracy, and maintenance-free. This improves the handling of the bike making it much more intuitive and enjoyable to ride, while also making it safer.
Removable Seatpost Battery
The D21 comes with a top-notch 36V 11.6Ah battery, which improves the overall convenience factor of this foldable electric bike by a great margin. How? It is a removable seat battery that you can charge both in-frame or externally. Also, the battery is designed to last long to offer an extensive range of up to 100km (62mi).
Top-Notch Gear Shifting System
Shimano is known industry-wide for its commendable components and vehicle parts. This is exactly why Fiido D21 has a Shimano 7-speed gear shifting system. Furthermore, this transmission mechanism allows the user to pick from 3 adjustable levels, hence making it easier for different types of riders to make their foldable electric bike conform to their riding style!
Praiseworthy Body Structure
The D21 body is made of aerospace-grade aluminum alloy, and its weight does not exceed 18kg. And its body is ergonomically designed, so it doesn’t get tired after a long ride, making the D21 as light as possible without compromising its performance and comfort.
Fiido D21 has a 250W motor, which although sounds not all that powerful, accounts for the compactness and lightweight of this foldable electric bike.
