Most commuter e-bikes are built for one type of riding and slightly awkward at everything else. The Fiido C21 is different — and at just 17.5 kg, it's the sort of bike that shifts seamlessly between a Monday morning commute through city traffic and a Saturday afternoon exploring a gravel path or canal towpath without feeling like it's compromising on either.

The Mivice torque sensor is what makes the ride quality stand out. It reads how hard you're pedalling and adjusts assistance accordingly — smoothly and proportionately. Whether you're pushing into a headwind, sprinting between lights, or climbing a steady hill, the C21 responds naturally. The 250W motor and up to 100 km of assisted range give you the freedom to go further on a daily commute or push for a longer weekend route without obsessing over battery percentage.

Light, agile, and easy to handle

17.5 kg is meaningfully lighter than most mid-range commuter e-bikes — and you feel it. The C21 moves through traffic with real agility, picks up speed without effort, and doesn't feel sluggish when you're weaving through a busy cycle path or making tight turns. The centred display keeps your ride data clearly visible without needing to look down at an awkward angle.

Ready for mixed surfaces — not just smooth roads

The CST/KENDA 27.6 × 1.57 tyres and hydraulic disc brakes keep the ride stable and controlled across city streets, light gravel paths, and mixed-surface routes — exactly the kind of variety a UK commuter encounters between home and office. IP54 water protection means you're not watching the weather forecast before leaving the house. Riders from 5'3" to 6'9" are well accommodated with the adjustable seat.

If you want a lightweight commuter e-bike that's equally at home on a weekday commute and a weekend adventure — the Fiido C21 is one of the most versatile options at this price point.

Key Features

17.5 kg Lightweight Build — Agile, Easy to Handle Every Day
Noticeably lighter than most mid-range commuter e-bikes. Responsive through traffic, easy to manoeuvre in tight spaces, and light enough to lift or carry without it being an ordeal.

Mivice Torque Sensor — Smooth, Adaptive Assistance
Reads your pedal effort and responds proportionately — natural and intuitive rather than mechanical. Makes the whole riding experience feel closer to a great conventional bike than a motorised one.

Up to 100 km Assisted Range — Freedom to Ride Further
Covers commutes, errands, and longer weekend rides without constant recharging. More than enough for most UK riders' weekly routines.

Hydraulic Disc Brakes — Confident Control on City and Gravel
Progressive, consistent stopping power across city streets, gravel paths, and mixed-surface routes. Reliable in wet and dry conditions.

CST/KENDA 27.6 × 1.57 Tyres — Stable Across Mixed Terrain
Smooth and composed on tarmac; capable and controlled on light gravel and mixed paths. A versatile choice for riders whose routes aren't always predictable.

IP54 Weather Protection — Year-Round UK Commuting Confidence
Rides in rain without hesitation. Built for the British climate, not just dry-weather use.
