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.”

Great e-bike. Not unlimited range, in these hilly surroundings, where I live, but it makes up for it, being light and quite easy to use, even without power

This has been a pleasant surprise!
Easy to put together
For such a small battery this bike just goes and goes. I’m using it in Copenhagen and there are no hills but I still get up to 60-70km from it!

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 ! ‍♀️✨
