Electric bikes (e-bikes) are gaining traction across the UK as a practical, eco-friendly solution for commuting, staying active, or enjoying the countryside.
The Fiido E-Gravel C21 Electric Bike stands out as an affordable, lightweight option that doesn’t compromise on style or performance. Priced at £1,090.00, this e-bike is designed for urban riders, fitness enthusiasts, and those who enjoy a bit of light off-road exploration. In this review, we’ll dive into its key features, performance on British roads, and whether it’s worth your money.
Introduction
Picture a bike that’s light enough to carry up a flight of stairs, zips through busy streets in cities like London or Bristol, and handles wet weather or gravel paths with confidence—all for just £1,090.00. The Fiido E-Gravel C21 makes this a reality. Weighing only 17.5 kg (38.5 lbs), it’s one of the lightest e-bikes in its category, offering electric assistance without the heft. With a 250W motor, a 374Wh battery, and a clever torque sensor, it’s built to tackle the UK’s varied terrain, from rainy commutes to weekend rides along country lanes.

Key Features
The Fiido E-Gravel C21 packs a punch with features tailored to UK riders. Here’s what you get:
- Lightweight Frame: At 17.5 kg (38.5 lbs), it’s a breeze to lift or manoeuvre—perfect for flats with no lift or popping it onto a train.
- 250W Motor: The quiet Mivice hub motor delivers smooth assistance up to 25 km/h (15.5 mph), staying within UK e-bike laws. It switches off seamlessly when unassisted, feeling like a regular bike.
- 374Wh Battery: Offers up to 80 km (50 miles) of range, ideal for daily commutes or longer jaunts. It charges on the bike in 4-6 hours.
- Torque Sensor: This smart system adjusts power based on how hard you pedal, making hills and stop-start traffic feel effortless.
- 9-Speed Gears & Hydraulic Brakes: A 9-speed L-Twoo system ensures smooth shifting, while Tektro hydraulic disc brakes provide reliable stopping power in the rain.
- Gravel-Ready Tyres: The 700C, 40mm-wide CST tyres grip well on wet roads and light off-road paths like canal towpaths.
- Integrated Display: A clear handlebar display shows speed, battery, and assist levels, with an optional app for ride tracking.
- Extras: Full-length mudguards, a kickstand, and a front LED light come standard—vital for UK weather and visibility. Optional rear rack and range extender available.
Performance
The C21 shines across typical UK riding scenarios:
- Speed & Power: Capped at 25 km/h (15.5 mph), it’s perfect for city commuting or leisurely rides. The torque sensor makes assistance feel natural, whether climbing a hill or weaving through traffic.
- Range: Expect 48-80 km (30-50 miles) per charge, depending on conditions. That’s plenty for a week of commutes or a day out in the countryside.
- Handling: Its sporty yet comfy frame and grippy tyres make it agile on busy streets or light gravel. The saddle suits longer rides too.
- Braking: Hydraulic disc brakes stop confidently, even in drizzle—a big plus for UK conditions. The front light boosts visibility, though the rear light needs separate charging.
- Off-Road: It’s great for light gravel or towpaths but not rugged trails, lacking suspension for rougher terrain.

Pros and Cons
Here’s the rundown:
Pros
- Great Value: At £1,090.00, it’s a steal for its tech and build.
- Light & Portable: Easy to carry or store in tight spaces.
- Smooth Ride: The torque sensor gives a natural, responsive feel.
- Versatile: Handles urban streets and light off-road equally well.
- Battery Life: Solid range for daily use.
- Looks: Sleek design with hidden wiring—doesn’t scream “e-bike.”
Cons
- Fixed Battery: Non-removable, so charging needs a nearby plug.
- Light Off-Road Only: Not built for tough trails.
- Big Chainwheel: The 52-tooth chainwheel might challenge some on steep climbs (replaceable).
- No Throttle: Pedal-assist only, per UK norms.
- Assembly: Mudguards and display take time to fit.

Conclusion
The Fiido E-Gravel C21 is a brilliant choice for UK riders seeking an affordable, lightweight e-bike. For £1,090.00, you get a versatile machine that excels in urban settings and light off-road jaunts, with a natural ride feel thanks to its torque sensor. It’s not perfect—the fixed battery and limited off-road chops might irk some—but these are small gripes for the price.
If you want a stylish, practical e-bike for commuting through rainy cities or cruising British paths, the C21 delivers. It’s ideal for first-timers or anyone after a lightweight option that doesn’t cost the earth.
Verdict: A top pick for UK commuters and casual riders. Look elsewhere if you need rugged off-road power or a throttle.
