Fiido C21 Review - Does Not Look Like an E-bike!
La meilleure option sans aucun doute est de l'utiliser pour aller au travail.
THIS E-BIKE IS AMAZING!!! I FELL IN LOVE!
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.”

Fun bike

Super fun bike. It is fast and agile due to its light weight. It was easy to assembly except for the fenders, that took me more time to put them on than the bike itself.
I totally recommend it!

Lars Ringgaard Sørensen
Great bike at a reasonable price

I am happy with my purchase. But a relatively small battery, lack of range compared to range stated by Fiido, and a non removable battery pack only leads to 4 stars.

Carlos De Madrid Balbuena
Increible!!

I bought it from a dealer in Barcelona (Spain) and I'm delighted with the C21. It's impressive for the price. I've had several MTB e-bikes with powerful batteries and motors, but if you have legs and know how to manage the battery, this one is great.
Congratulations!!

Ma commande est arrivée assez rapidement. Le vélo était bien emballé. Tout était fait pour un montage simple et assez rapide. Seule, la batterie de secours est arrivée avec du retard, mais rien de dérangeant, le suivi a été sérieux.!

Bonjour ! Merci beaucoup pour votre retour 😊 Nous sommes ravis que l’emballage et le montage aient été simples et rapides ! Merci aussi pour votre compréhension concernant le léger retard de la batterie de secours, nous continuerons à assurer un suivi sérieux. Nous vous souhaitons de belles balades, et n’hésitez pas à nous contacter si besoin ! ‍♀️✨

Das sollte natürlich nicht passieren, und ich verstehe deinen Frust. Wir möchten dir helfen, eine Lösung zu finden. Bitte versuche, den Kundensupport erneut zu kontaktieren unter support@fiido.com oder schreibe uns direkt hier, damit wir sicherstellen können, dass dein Anliegen schnell bearbeitet wird. ✨

Zrobione już ponad 500 km i klocki z przodu przy hamowaniu dalej wydają dziwny metaliczny odgłos

Dzięki za info i gratulacje za już ponad 500 km! 💪‍♂️
Jeśli przednie klocki nadal wydają metaliczny dźwięk, może to być kwestia zużycia, ustawienia albo drobinek metalu na tarczy.
