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 Vélo Électrique Dyu C9 easy to assemble?

The Vélo Électrique 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 Vélo Électrique Dyu C9 water resistant?

The Vélo Électrique 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.

Description

Résumé rapide
Le DYU C9 20″ Long-Range Electric Bike est un vélo électrique pliable haut de gamme conçu pour les trajets en ville, les tournées et les aventures quotidiennes. Combinant un moteur efficace de 250 W avec une batterie amovible de grande capacité de 48V 15.6Ah, il offre une autonomie impressionnante qui peut atteindre jusqu'à 150 km sur l'assistance au pédalage et une conduite douce et réactive qui est parfaite pour les rues urbaines et les sentiers hors route légers.

Puissance souple et réactive
Le moteur sans balais de 250 W fournit une assistance au pédalage fiable jusqu'à la vitesse maximale légale de 25 km/h au Royaume-Uni et dans l'Union européenne, tandis que les pneus larges de 20″ et le cadre absorbant les chocs assurent une conduite confortable sur des surfaces allant des routes pavées aux chemins de gravier.

Performance de la batterie à longue portée
Avec sa grande batterie de 15,6 Ah, le C9 est conçu pour les longs trajets et les déplacements quotidiens sans recharge constante. Les distances réelles peuvent varier en fonction du niveau d'assistance, du terrain et du poids du cycliste, mais l'efficacité du système de batterie fait entrer ce modèle dans la catégorie des vélos électriques pliables à grande autonomie.

Confort et contrôle
Les freins à disque hydrauliques offrent une puissance de freinage forte et constante dans des conditions variées, tandis que la géométrie ergonomique du cadre et les composants de la suspension atténuent les bosses pour une conduite plus agréable. L'écran LCD permet de visualiser la vitesse, le niveau de batterie et le mode d'assistance d'un seul coup d'œil.
