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.”

So far a great bike and good experience.

As a bike that is my daily commuter I am really happy with the bike, its operation, build and feel. Meets my 14 mile commute perfectly. Delivery times where not honest in the website saying it was in stock and having to wait for shipping for bike and accessories coming from china, some taking 7weeks. Only other minor comment is it would be good to see more sustainable information on the bike, including repairability spares and recycled materials. Overall though really happy.

Authentic Fiido review C21 Step over.

I ordered my E-Bike and recieved it 9 days later. After completing construction I have had no issues whatsoever. The only thing I will say is I have struggled to reach the desired distance specified. However I have comfortably done 41km and 39km after 1 Charge. Arrived with full charge, most appreciated. 10 days later my accessories arrived. Rear rack, rack bag and mobile phone attachment. All as expected and without any faults at all. I can honestly say I have nothing but positivity towards Fiido in every aspect of my purchases. All I would say is be patient, jumping all over customer services isn't necessary for a few days delay. It puts unnecessary strain on them and causes you anxiety which I believe reflects the bad reviews prior to delivery. Stay safe and enjoy your new product.

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

Hello!

Thank you so much for being a member of the FIIDO! Hope you are enjoying the ride. Our team will really appreciate your kind words. Please feel free to let us know if you have any further questions. Happy Riding!

All the best,

Fiido C21 Review (Edinburgh): Riding Like a Dream for Four Months

The purchase of the Fiido C21 was the beginning of an extraordinary cycling experience. For four months, this bicycle was my daily means of transport in the city of Edinburgh, and its performance was exceptional, meeting the quality and ride one should expect from an e-bike.

Reliability: The Clear Winner

The most important thing I learned from my experience with the C21 is the bike's incredible reliability. The bike performed faultlessly for the entire four months I owned it. There were no mechanical setbacks, no surprise failures, and no work beyond routine maintenance on the bike, and the C21 exceeded expectations for a commuting bike.

Performance & Commuting

The C21 performed well in the challenging environment that Edinburgh presents. It started with quality wheels and a well-balanced weight, which worked well in its favour for stability and manoeuvrability. The C21 offers the right amount of power and stability to take on the hills and to be in control while descending. The C21 has the robust, well-crafted feel of a bicycle designed to take on the challenging urban ride, performing well on Edinburgh's diverse terrain. Rides with the C21 are a delight, making commuting a pleasure to look forward to.

Battery System: Integrated Design and Essential Range

"The power system is a characteristic element of the C21. It has a cleverly designed internal battery, mounted inside the frame, adding to the sleek and light design of the bike—it is quite comforting to know that the basic source of the bike’s power is contained within."

Having said that, if one intends to take the e-bike out for a commute or to ride through the hills of Edinburgh, the Extended Range Battery will be a handy addition to the equation. Though the internal battery capacity of approximately 208Wh is quite a good base for the e-bike, the presence of the external extender will make long-distance travel much more straightforward and remove any thoughts of range anxiety altogether.

Final Thoughts (Before the Theft) The only thing keeping this review from being longer is the unfortunate events: the bicycle was stolen after four months of perfect performance. Though sad, the fact that my experience was cut short by bicycle theft, not by any issues with the bike itself, clearly indicates how much I liked the product. I wholeheartedly recommend the C21 to anyone looking for a reliable mid-range e-bike for city riding.

Excellent build quality and value

The C21 arrived promptly, was easy to assemble and I have to say, I am really pleased with the build quality. I have only used it a couple of times so far but I am impressed with the way it performs, it is great, very responsive. Probably because it is very light for an electric bike.
So far so good, smooth and feels very good 👍 👍
