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.”

WOW what a bike.

Took delivery yesterday afternoon and within 2 hours I was on the road. The assembly was so easy and all went together superbly. The only fiddly bit was the fenders as no assembly instructions were supplied for them. Thoroughly recommend this gravel electric bike

The seat could be a bit softer. Perhaps a thicker cushion. Otherwise I would have given it 5 stars.

Dear Customer,

Thank you very much for choosing the Fiido C21 E-Bike and for taking the time to provide your valuable feedback. We fully understand your concerns regarding riding comfort. Every rider has different body types, riding habits, and riding durations, so their comfort needs may vary.

To accommodate most users, we have designed the saddle to be compatible with a variety of options. You can easily replace it with a seat that better suits your personal preferences and riding habits. For example, you can choose a softer city-style seat or an ergonomic seat more suitable for long-distance riding. This can improve riding comfort and make every ride more enjoyable.

Once again, thank you for your purchase and valuable feedback. We wish you enjoyable rides!

Best regards,
Fiido Team

Bike is fantastic for a first e bike. Bike is really good, brakes stop on point when I sqeeze really hard. Tires are good especially the road I take for work, even on the shortcut roads that are gravel. The speed could be a bit better can only go up to 16 with the pedal assistance after that it gets harder to pedal which I understand the safety, but another e bike I borrowed would go up to 22 before it stop the pedal assistance. The only issue i mainly have is the handle bars. For medium size it is low, wish it was a bit higher, but I am 5'7" that is the only big issue that I have. Overall really good first e bike, will probably get the battery in the future.

Good, but not great, for the money

The bike was great out of the box, as I was moving from a 100lb fat tire ebike (cadence sensor) to this lightweight beauty.
With the torque sensor, I felt like I was riding a bike again instead of an electric motorcycle. Responsive, smooth, and could easily take up any stairs I encountered.
Smooth shifting, but disappointed that this is only a class 2 ebike, with a top assisted speed of 20. My bad for missing that in my comparison before I purchased.
Range is as-expected. 20-25 miles on Turbo+ with some hills thrown in. I've got my big bruiser for going further, so I've gladly traded range/speed for lightness.
Things that could be better:
- Fenders were a pain to adjust. Took me longer to put the fenders on than assembling all the rest of the bike.
- Rear rack is awkward for most panniers that clip on. Tried three and the best one still doesn't give me confidence if I have a heavy load.
- Rear light is silly. At this price point, most lightweight bikes don't have a wired rear light, but the one they include could have a larger battery. Lasts maybe 3 rides of 15 minutes each.
- Pedals are worthless. Again, not uncommon at this price point, but plastic pedals with no grip should be outlawed.
If I had to do it again, I'd spend another $300-400 and get a class 3 lightweight bike.

Dear Rider,

Hello! Thank you very much for sharing your detailed experience with the C21. We can truly understand that moving from a heavy fat-tire e-bike to the lightweight C21, you were expecting a smoother and more effortless ride. We’re very glad to hear that you enjoyed its lightness and the natural riding feel brought by the torque sensor.

Regarding the points you mentioned, we fully understand:

Top assisted speed: The C21 is factory-set with a pedal-assist limit of 25km/h (around 20mph), which is designed according to regulations in most markets and for safety considerations. We understand your wish for higher speed, and we’ll keep this valuable feedback in mind when planning future products.

Fenders: Installing the fenders can indeed be a bit tricky. We provide an official installation video as guidance, and we’re happy to see that you managed it successfully—your patience and hands-on ability are impressive.

Rear light: The C21 was designed as a sleek and lightweight city e-bike, so it does not come with a wired taillight. Instead, we include a detachable one as a complimentary accessory. Under normal conditions, it lasts about 2 hours of continuous use. We understand your need for longer endurance, and we’ll take this suggestion into account for future improvements.

Rear rack compatibility: The rear rack is designed with lightness in mind, which may cause compatibility issues with certain panniers. Your feedback is very helpful, and we will consider ways to improve compatibility in future designs.

Pedals: The stock pedals are lightweight standard components, but we understand that some riders prefer sturdier pedals with more grip. That’s why the C21 is designed to use widely compatible standard parts, making it easy for riders to upgrade and customize according to their preferences.

We truly understand that when your expectations differ from the actual experience, it can feel disappointing. At the same time, we are grateful for your honest feedback, as it helps us recognize both the strengths of the product and the areas where we can do better. Your experience matters a lot to us, and we sincerely hope to make every ride enjoyable for you.

Thank you once again for your patience, understanding, and support. We wish you safe and joyful rides ahead!

Best regards,
The Fiido Team
