You Save 25% (
Choosing your folding electric bike is a difficult task! However, with our upgraded Fiido D21 Torque-Sensing Electric Folding Bike, you will have everything you need for a pleasant riding experience. This folding electric bike comes with a powerful 36V battery that allows for a top speed of 25 kilometers per Hour and a range of up to 100 kilometers.
Fiido's unique folding electric bike aesthetics endow D21 with the perfect balance of form and function. The 35nm 250W brushless geared motor is hidden in the 20-inch rear wheel and provides tremendous power despite its compact size and lightweight, allowing you to easily overcome rugged and steep roads while consuming very little energy. This improves the bike's handling, making it more intuitive and enjoyable to ride while also making it safer.
The compact design features an integrated seat post that houses the battery and taillight, reducing the number of components and maximizing efficiency. In addition to the use of an aerospace-grade lightweight aluminum alloy frame, the model's layout also adheres to ergonomic design specifications, providing a comfortable riding experience with a height-adjustable leather seat.
Fiido D21 250W 36V Torque-Sensing Folding Electric Bike Features:
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.
250W High-Efficiency Motor:The 35nm 250W brushless geared motor hidden in the 20-inch rear wheel provides tremendous power even in a compact size and lightweight, which is the reason why it can easily overcome rugged and steep roads with extremely low energy consumption.
Specially Design Battery:The battery is concealed in the seat tube, making it nearly tantamount to an ordinary bicycle at first glance, nevertheless, the range can still reach 100KM under the electric moped mode despite being so compact. Furthermore, the battery is removable meaning that you may get it powered anywhere at any time.
Praiseworthy Body Structure: The concise design with integrated Seatpost that contains battery and taillight, reducing the number of components and improving efficiency to the full extent. In addition to the utilization of an aerospace-grade aluminum alloy frame, the layout of the model conforms to the ergonomic design specifications, presenting a comfortable riding experience with a height-adjustable leather seat and a light self-weight of 12.9kg only.
So far I have not had problems with the bike. The battery life exceeded my expectations.
Cool bike of premium quality
- very lightweight
- very robust
- strong motor
- good gearshift
- recommendable torque sensor
The delivery was good and it was not damaged. Easy to put together though a you tube guide for the mud guards was helpful. Great fun to ride and lots of power to get up hills. Having the battery in the seat post is good because if I lock it up when I am out I remove the seat post and take it with me.
Let customers speak for us
from 423 reviews
This bike is great. I’m a first time e-bike user. From the look and design of the bike to the power and comfort, this bikes great. I took it out for 8 miles on my first day and it performs well. I have big hills where I live, so I don’t expect battery life to be as well as someone just getting around in the city on flat surfaces. I had one bar drained after my 8 mile ride, that’s good considering the hills and in sport mode. I was pedaling up the hills then using full throttle on the flat surfaces and traveling at 18 mph. I changed the parameters of the bike( which you can find out more about on YouTube) and now the bike will do 26 mph pedaling and 20 mph throttled. If you want to get a e-bike, I would recommend this one if you’re taller. This things a beast. I’m 6’0 and weigh 240 lbs.
The customer support of Zoom Electric Bikes is great too. I had a bad battery on arrival and they rushed me a new battery.
Being a more affordable electric bike I wasn’t sure what to expect. I love it!! It was easy to assemble and is a great looking bike. The battery is amazing, been on four rides and my battery is at about 80%. Extremely satisfied with my purchase.
This e-bike is powerful! When they told me "hang on" .. they weren't kidding. You can feel the power from each wheel. Each wheel has its own 1000w hub motor so this bike truly defines All Wheel Drive. And the power going uphill...I weigh 245-250 lbs and this bike has no problem carrying me around anywhere. Well done Rambo!
I bought this bike to be more green. I love the way it drives. With and without batteries. I had a minor issue but their customer service is helping every step of the way. I love this cargo bike, and for the money you can’t do better. Thanks for a cool product
I want to thank Zoom for a great bike , very easy to assemble. I find myself waiting for the next opportunity to venture out on my e bike. I’m a middle aged man so I can appreciate the ride this bike offers. A+
