Minimalist elegance – you can’t tell it’s an e-bike.

The Story of the Fiido C21

Keven, the CTO at Fiido, found his inbox flooded with requests for 700c electric bikes. Customers loved their ability to handle gravel roads, but most models on the market were heavy and expensive. Driven by this feedback, Keven and his team created the C21, an affordable, lightweight 700c ebike. Designed with urban cyclists in mind, the bike features advanced smart technology and a striking urban aesthetic. The C21 made an immediate impact upon release, with Forbes praising it as one of the best gravel e-bikes, highlighting its "exquisite craftsmanship, beautiful appearance, and precise riding experience."
