What range should I actually plan around on the C3?

DYU's current UK page lists roughly 25km in pure-electric use and about 34km with pedal assistance. Those figures line up with the detailed range table and are a better planning guide than vague 'all day' marketing claims.Use less than the maximum for real journeys, particularly in cold weather, on hills, or if you rely heavily on electric power rather than adding pedal effort.

How much can I put on the C3 rear rack?

DYU lists the C3 rear shelf at up to 25kg. That does not mean you should ignore the bike's overall rider/load limit, and the rack is for luggage only, never a passenger seat.

Is the C3 genuinely portable enough for stairs and public transport?

It is compact, but not featherweight. DYU lists the C3 at about 20kg, so the folding design is most useful for reducing storage size and fitting the bike into a vehicle.For occasional stairs it may be manageable, but if you expect to carry the bike frequently, the weight should be tested against what you are comfortable lifting.

Is the DYU C3 Mini Electric Bike easy to assemble?

The DYU C3 Mini Electric Bike arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.

Is the DYU C3 Mini Electric Bike water resistant?

The DYU C3 Mini Electric Bike is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.

Description

The DYU C3 Mini Electric Bike is a compact, foldable city e-bike designed for short commutes, last-mile journeys, and easy storage. With a 250W rear motor, integrated 36V 7.5Ah battery, and ultra-compact 14" wheels, it’s ideal for riders who want a simple, go-anywhere electric bike that’s easy to lift, park, and store.

Smooth Power Delivery
The DYU C3 uses a 250W rear hub motor tuned for smooth acceleration up to 25km/h, keeping it compliant with UK/EU e-bike regulations. Two riding modes let you choose between pure electric drive for effortless cruising or pedal assist to extend your range and add a bit of exercise.

Comfort & Control
Although it’s a mini e-bike, the C3 is built for everyday comfort. The 14×2.125" city tyres provide a wider contact patch than standard mini-bike tyres, helping absorb bumps and improving grip on tarmac, paving and cycle paths. A spring suspension seat post and ergonomic saddle help take the sting out of rougher surfaces, while the low-step frame design makes mounting and dismounting easy, even in stop-start urban riding.

Smart Battery System
The frame-integrated 36V 7.5Ah lithium-ion battery is sized for short to medium city journeys. In ideal conditions, you can expect approximately 20–25km in pure electric mode and around 30–40km with pedal assist, depending on rider weight, terrain and temperature.
