Fiido C21 Review - Does Not Look Like an E-bike!

Fiido C21 REVIEW: The Ultimate Lightweight Electric Gravel Bike 2025?
THIS E-BIKE IS AMAZING!!! I FELL IN LOVE!
The E-Bike For (Almost) Everyone?!
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.”
