Fiido C21 Review - Does Not Look Like an E-bike!

The E-Bike For (Almost) Everyone?!
Fiido C21 REVIEW: The Ultimate Lightweight Electric Gravel Bike 2025?
Fiido C21 & Fiido C11 Pro E-Bike Review | Tested in Amsterdam, the Bike Capital!
From Request to Reality
Fiido’s CTO Keven was flooded with requests for a 700C e-bike. Riders wanted gravel-ready performance—without the bulk or high price. In response, the team created the C21: lightweight, affordable, and built for urban exploration.

With smart features and sleek design, the C21 made an instant impact. Forbes praised it as one of the best gravel e-bikes for its “exquisite craftsmanship, beautiful appearance, and precise riding experience.”

An item/a part is missing from my order — what should I do?

📌 Reason: Small parts may get stuck in the packaging or the package may be opened during transit.

Please keep the original packaging and all components for at least 30 days after delivery. This helps with any necessary repairs or returns.

A VERY Frustrating Purchase

I ordered a C21 L and a C21 M on June 6, 2025. The day after placing my order, I was notified that the C21 M was not in stock, but I could wait until July 30th for it to ship (when it was scheduled to be back in stock), or they could ship a 2nd C21 L in its place. I was not willing to wait two months for a bicycle I had already paid for, so I opted for the 2nd C21 L. Just explaining THAT to customer service took several emails/days. The first C21 I received was great - a lovely bike! My only complaint is that the pedals were extremely difficult to screw into the crank arms. When my 2nd C21 arrived, it was obvious that the bicycle had either been a display model, or had been returned. In fact, it was not even the updated model, but an earlier model of the bicycle. I contacted customer service on June 15 to inform them of the situation, and requested either a refund or updated parts for the bicycle. They said they would send updated parts (the multi-function switch and the saddle). Three emails and two months later I still have not received the updated parts for the 2nd, older C21 I was shipped. This whole process has been very frustrating, and I feel like I paid for a second-hand product.

Dear Rider,

Hello! Thank you very much for taking the time to share your detailed experience with us. We completely understand that the waiting and back-and-forth communication must have been very frustrating, and we sincerely apologize for the inconvenience caused.

We are delighted to hear that you enjoy your first C21, and at the same time, we are truly sorry that the second C21 did not meet your expectations. Please rest assured that Fiido does not sell any second-hand or returned products. The difference between the two bicycles may be due to variations in different production batches.

We take your case very seriously, and we have already arranged to send you the missing updated parts (the multifunction switch and the saddle). These parts are currently being processed, and we will ship them to you as soon as possible. Once the logistics information is available, we will share it with you immediately.

Your trust means a great deal to us, and we sincerely hope that by resolving this matter properly, you can once again enjoy a pleasant riding experience with your C21. Thank you again for your patience and understanding. Should you have any questions or need further assistance, please feel free to reach out to us at any time.

Wishing you all the best,
The Fiido Team
