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!

Ottima bici

Ottima bici! A causa del limite di legge alla velocità e quindi di un blocco al motore ho sentito poca differenza fra le varie modalità: solo nell'assistenza immediata, dopo i 25kmh faccio comunque tutto io. Per questo dovrò modificare la trasmissione per permettermi uno sforzo inferiore nella spinta. Unica pecca è, appunto, il sistema di trasmissione: una più performante permetterebbe delle prestazioni migliori. In ogni caso è una bici ben fatta e performante. Le ruote grandi aiutano con le vibrazioni. Una forcella ammortizzata aiuterebbe anche per le grandi imperfezioni del terreno, ma per un uso cittadino è veramente ottima. Ho fatto anche viaggi di più di 60 km e in modalità Eco la bici arriva a destinazione e lo sforzo rimane poco. Ripeto che la trasmissione aiuterebbe molto.
La comodità della postura è ben diversa da una fat bike o da una bici da città: perciò le vibrazioni sulle spalle e sui polsi sono molti: un tipo differente di grip e di manubrio potrebbe aiutare a rilassare le spalle. Assieme ad una forcella ammortizzata, un manubrio più ergonomico e una buona trasmissione diventa una bici perfetta. Per come esce dalla fabbrica è veramente la miglior bici qualità-prezzo che c'è sul mercato delle e-bike legali.
