How portable is the C9 once it is folded?

The C9 folds to roughly 97 × 46.5 × 76cm, which is very useful for storage and can make vehicle transport much easier than a non-folding city bike.However, it weighs about 30kg. The folding mechanism reduces its size, not its weight, so this is not a bike most people will want to carry up stairs or through a station regularly.

Are the C9 brakes and suspension a meaningful upgrade for longer rides?

Yes. DYU equips the C9 with hydraulic disc brakes and a suspension system, which gives stronger braking feel and better bump control than a basic rigid compact folder on longer or rougher journeys.

Who should choose the C9 instead of the FF500 or C6 Pro?

Choose the C9 if long battery range and a folding 20-inch format are the priorities. Choose the FF500 if you specifically want wide fat tyres and a more rugged-feeling setup, or the C6 Pro for a conventional 26-inch step-through city-bike layout.The C9 is the most storage-friendly of those long-range choices, but at around 30kg it is still a substantial bike to lift.

Is the Bicicleta Eléctrica Dyu C9 easy to assemble?

The Bicicleta Eléctrica Dyu C9 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 Bicicleta Eléctrica Dyu C9 water resistant?

The Bicicleta Eléctrica Dyu C9 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.

Resumen rápido
La bicicleta eléctrica de largo alcance DYU C9 20″ es una eBike plegable premium diseñada para desplazamientos urbanos, viajes y aventuras diarias. Combinando un eficiente motor de 250 W con una batería extraíble de alta capacidad de 48V 15,6Ah, ofrece una impresionante autonomía que puede alcanzar hasta 150 km con pedaleo asistido y una conducción suave y con gran capacidad de respuesta, perfecta para calles urbanas y caminos ligeros fuera de carretera.

Potencia suave y sensible
El motor sin escobillas de 250 W proporciona una asistencia al pedaleo fiable hasta la velocidad máxima legal en el Reino Unido/UE de 25 km/h, mientras que los anchos neumáticos de 20″ y el cuadro amortiguador ofrecen una conducción cómoda en superficies que van desde carreteras asfaltadas hasta caminos de grava.

Rendimiento de la batería de largo alcance
Con su gran pack de baterías de 15,6 Ah, la C9 está pensada para viajes largos y desplazamientos diarios sin recargas constantes. Las distancias reales pueden variar en función del nivel de asistencia, el terreno y el peso del ciclista, pero el eficiente sistema de la batería sitúa a este modelo en la categoría de eBikes plegables de larga autonomía.

Confort y control
Los frenos de disco hidráulicos proporcionan una potencia de frenado fuerte y consistente en condiciones variadas, mientras que la geometría ergonómica del cuadro y los componentes de la suspensión suavizan los baches para una conducción más agradable. La pantalla LCD ofrece una visibilidad clara de la velocidad, el nivel de batería y el modo de asistencia de un vistazo.
